Lift is reported as diagnostic evidence and does not override this gate. +- The 50% attempt pass threshold is a separate per-task gate; it is not the dimension pass threshold. +- Effectiveness is the equal-weight mean of goal completion (`goal_accuracy`) and expected workflow adherence (`behavior_check`). +- Efficiency is 50% tool-call productivity (the backward-compatible `skill_efficiency` wire id) and 50% `token_efficiency`. Positive-case skill routing is scored under Discoverability, not Efficiency; a negative case without a routing target is N/A. N/A sources are omitted, remaining weights are renormalized, and the dimension is marked partial. + +Signals present in this run: + +- `security` (Security): unsafe operations, secret leakage, and unauthorized access. +- `skill_execution` (Skill Execution): whether the expected skill was selected, decoys were avoided, and the workflow executed. +- `skill_efficiency` (Tool Productivity): tool-call productivity (legacy wire id; routing is scored under Discoverability). +- `accuracy` (Accuracy): final-answer correctness against the reference answer. +- `goal_accuracy` (Goal Accuracy): whether the user's goal was achieved. +- `behavior_check` (Behavior Check): whether the expected workflow behavior was followed. +- `token_efficiency` (Token Efficiency): actual uncached prompt plus completion usage (50% of Efficiency). + +

Pull the per-pool quota distribution +`list_project_resources` (paginate). For every (node_pool, project) GPU cell keep: +`deserved`, `allocated`, `limit`. Derive `over_quota_used = max(0, allocated − +deserved)` and `deficit = max(0, deserved − allocated)`. Skip cells with +`deserved == null` and `allocated == null` (nothing assigned, nothing running). + +### 2. Detect *genuine* pending demand (for STARVED) +For each project with a `deficit > 0`, call +`get_workloads_summary(orgType="project", orgName=)` — **project-scoped, +no `nodePoolName`** (pending pods are unscheduled, so a node-pool filter returns +`pending = 0` and hides the starvation). Read `pending` under `counts`. If `pending > 0`, +**inspect the pending reason**: call `list_workloads(phase="Pending", +projectName={operator:"==", value:})` for the IDs, then +`get_workload_status(workloadId=)` and read `phaseMessage` — a pending count +alone is not starvation: +- ✅ counts as STARVED: *waiting for deserved capacity held by others* (pool full / + reclaim not yet done). +- ❌ does NOT count: *"GPU quota exceeded for non-preemptible workloads"* (the + project asked for non-preemptible capacity beyond its own deserved — self-inflicted), + or an *unschedulable spec* (a workload problem, not a fairness one). + +Only the "waiting for deserved capacity" case, combined with `deficit > 0`, is +starvation. See `references/quota-accounting.md` — preemptibility governs borrowing, +and non-preemptible-over-quota pending is a common false positive. + +### 3. Classify each (pool, project) cell +- **OVER_BORROWING** — `allocated` exceeds `deserved` (`over_quota_used > 0`). + Magnitude = `over_quota_used`. +- **STARVED** — `deficit > 0` **and** *genuine* pending exists for that cell (pending + whose reason is waiting-for-capacity/reclaim, per step 2 — not + non-preemptible-over-quota or an unschedulable spec). +- **WITHIN_QUOTA** — otherwise. + +### 4. Department roll-up +`list_department_resources` for each department's own deserved; aggregate its +projects' `allocated` from step 1. Flag departments whose net allocated exceeds +department-deserved. + +### 5. Per-pool over-subscription check +For each pool, get its GPU capacity from `get_cluster_physical_inventory` and compute +`sum(deserved)` across all projects in that pool. If `sum(deserved) > capacity`, the +pool is **OVER_SUBSCRIBED** — not every project's guarantee can be honored at once, so +a project can be starved *even though no one is borrowing*. + +### 6. Diagnose each STARVED project — cause drives the fix +Starvation has more than one cause, and they need different fixes. For each STARVED +(pool, project), determine which applies **in that pool**: +- **BORROWING** — a same-pool **OVER_BORROWING** project exists. The borrower is + holding GPUs the starved project is entitled to. *Fix:* reclaim + `min(borrower's over_quota_used, starved deficit)` from the borrower. This is the + classic fairness violation — name the starved+borrowing pair and lead with it. +- **OVER_SUBSCRIPTION** — no same-pool borrower, but the pool is OVER_SUBSCRIBED + (step 5).

Then the + borrower is holding GPUs the starved project is entitled to. +- **Reclaim** targets *over-quota* (unrequested-by-right) capacity only. The + scheduler reclaims from over-quota borrowers to satisfy in-quota demand. +- **In-quota protection is a priority, not a hard guarantee.** The scheduler + prioritizes protecting in-quota workloads from reclaim, but under contention it + is best-effort — do not promise a running in-quota job is untouchable. +- Reclaim ordering across departments has had edge-case bugs historically; when the + picture is close, present the numbers and flag uncertainty rather than asserting + a precise reclaim sequence. + +## Preemptibility governs borrowing (critical) +- **Non-preemptible workloads are capped at the project's `deserved` quota.** They + cannot borrow over-quota — a non-preemptible request beyond deserved goes Pending + with reason *"GPU quota exceeded for non-preemptible workloads."* +- **Only preemptible workloads borrow** into over-quota (unreserved) capacity — and + the scheduler can reclaim them for in-quota demand. +- Consequence: a *stable* same-pool "starved + over-borrowing" pair is rare. A + borrower must be preemptible (so it's reclaimable) — so the moment an in-quota + project needs its deserved, the scheduler reclaims and the starvation resolves. + Persistent starvation usually means **deserved quota is over-subscribed** (sum of + deserved on the pool exceeds capacity) or non-preemptible in-quota work fills it. + +## STARVED needs the pending *reason*, not just a pending count +`deficit > 0 AND pending > 0` is **not sufficient** — a project can be below deserved +with pending workloads for reasons that are *not* unfair starvation: +- **"…exceeded for non-preemptible workloads"** → self-inflicted: the project asked + for non-preemptible capacity beyond its own deserved. NOT starvation. +- **Unschedulable spec** (needs more GPUs than any node has, bad node selector, etc.) + → a workload problem, not a quota-fairness problem. +- **Waiting for capacity / reclaim** (pool full of others' usage, its deserved not + yet freed) → THIS is genuine starvation. + +So STARVED detection must inspect the pending workloads' reason (IDs from +`list_workloads(phase="Pending", projectName=…)`, then `phaseMessage` from +`get_workload_status(workloadId=…)`) and only count the "waiting for deserved +capacity held by others" case. Report the reason category, never just "N pending." + +## Two causes of starvation — they need different fixes +A project below its deserved with genuine (waiting-for-capacity) pending is starved, +but *why* determines the fix. Diagnose the cause before recommending anything: + +1. **Borrowing** — a same-pool project is OVER_BORROWING (allocated > deserved). It + holds GPUs the starved project is entitled to. *Fix:* reclaim + `min(over_quota_used, deficit)` from the borrower. This is the classic fairness + violation. +2. **Over-subscription** — no one is borrowing, but the pool's `sum(deserved)` + exceeds its GPU capacity, so not every guarantee can be honored. *Fix:* reduce + deserved / reassign quota. **Reclaim does not apply** — there is no over-quota + holder to reclaim from; inventing one gives wrong advice. +3. **Capacity** — no borrower, not over-subscribed: the pool is simply full of + in-quota usage. A capacity constraint, not a fairness problem. + +Why this matters: a well-behaved scheduler *prevents* case 1 (it reclaims +preemptible over-quota for in-quota demand), and non-preemptible work can't borrow at +all — so in practice **over-subscription is often the real cause**. A validated +example: node-pool-2 (32 GPU) with `hpc-fill` deserved 24 (running 16, non-preemptible) ++ `starved-svc` deserved 16 + `quota-hog` deserved 2 → 42 deserved > 32 capacity → +`starved-svc` gets only 12 of its 16, pends the rest. No borrower exists; the fix is +the over-subscription, not a reclaim. + +## Fractional GPU / swap caveats (do not misread `allocated`) +- A **fractional** request (e.g. `gpu-fraction: 0.5`) or a **multi-device + fractional** request (`gpu-fraction-num-devices: N`) still consumes + **device-count** quota, not memory-fraction quota. A project with quota "2 GPU + devices" is measured in devices. +- Therefore `allocated` for cells with fractional workloads may not equal raw + physical GPU cards — it reflects the scheduler's device accounting. Report it as + the platform reports it; do not "correct" it to card counts. +- With swap enabled, request vs limit can diverge widely (small request, large + limit); quota is generally checked against the **request/device count**, not the + swap limit.

+Audits GPU quota fairness across a Run:ai cluster, identifying which projects are starved and which are borrowing over their deserved quota in each node pool, and where GPUs can be reclaimed.
+ +This skill is ready for commercial/non-commercial use.
+ +## Owner +NVIDIA
+ +### License/Terms of Use:
+Apache-2.0 AND CC-BY-4.0
+## Use Case:
+Run:ai cluster administrators and platform engineers use this skill to audit deserved vs allocated GPU quota per project, department, and node pool, diagnose the cause of starvation (borrowing, over-subscription, or capacity), and get read-only recommendations on where GPUs can be reclaimed.
+ +### Deployment Geography for Use:
+Global
+ +## Requirements / Dependencies:
+**Requires API Key or External Credential:** [Not Specified]
+**Credential Type(s):** [None identified]
+ +Do not include secrets in prompts/logs/output; use least-privilege credentials; rotate keys as appropriate.
+ +## Known Risks and Mitigations:
+Risk: Review before execution as proposals could introduce incorrect or misleading guidance into skills.
+Mitigation: Review and scan skill before deployment.
+ +## Reference(s):
+- [Run:ai Quota Accounting — reference](references/quota-accounting.md)
+ + +## Skill Output:
+**Output Type(s):** [Analysis]
+**Output Format:** [Markdown with a summary line and per-pool and per-department tables]
+**Output Parameters:** [1D]
+**Other Properties Related to Output:** [Read-only; reflects a live snapshot of current cluster state and recommends reclaims without applying them.]
+ +## Evaluation Agents Used:
+- Claude Code (`aws/anthropic/bedrock-claude-opus-5-5`)
+- Codex (`openai/openai/gpt-6.1-sol`)
+ + + +## Evaluation Tasks:
+12 evaluation tasks (5 positive, 7 negative) replaying a frozen Run:ai testbed, run by each agent with and without the skill, one attempt per task, each in an isolated sandbox pod.
+ +## Evaluation Metrics Used:
+Reported benchmark dimensions:
+- Security: Is it safe to use?
+- Correctness: Is the answer correct?
+- Discoverability: Was the right skill loaded when needed?
+- Effectiveness: Did the skill help complete the task?
+- Efficiency: Did it avoid wasted tool calls and token usage?
+ +Underlying evaluation signals used in this run:
+- `security`: Unsafe operations, secret leakage, and unauthorized access.
+- `skill_execution`: Whether the expected skill was selected, decoys were avoided, and the workflow executed.
+- `skill_efficiency`: Tool-call productivity.
+- `accuracy`: Final-answer correctness against the reference answer.
+- `goal_accuracy`: Whether the user's goal was achieved.
+- `behavior_check`: Whether the expected workflow behavior was followed.
+- `token_efficiency`: Actual uncached prompt plus completion usage.

Lift is reported as diagnostic evidence and does not override this gate. +- The 50% attempt pass threshold is a separate per-task gate; it is not the dimension pass threshold. +- Effectiveness is the equal-weight mean of goal completion (`goal_accuracy`) and expected workflow adherence (`behavior_check`). +- Efficiency is 50% tool-call productivity (the backward-compatible `skill_efficiency` wire id) and 50% `token_efficiency`. Positive-case skill routing is scored under Discoverability, not Efficiency; a negative case without a routing target is N/A. N/A sources are omitted, remaining weights are renormalized, and the dimension is marked partial. + +Signals present in this run: + +- `security` (Security): unsafe operations, secret leakage, and unauthorized access. +- `skill_execution` (Skill Execution): whether the expected skill was selected, decoys were avoided, and the workflow executed. +- `skill_efficiency` (Tool Productivity): tool-call productivity (legacy wire id; routing is scored under Discoverability). +- `accuracy` (Accuracy): final-answer correctness against the reference answer. +- `goal_accuracy` (Goal Accuracy): whether the user's goal was achieved. +- `behavior_check` (Behavior Check): whether the expected workflow behavior was followed. +- `token_efficiency` (Token Efficiency): actual uncached prompt plus completion usage (50% of Efficiency). + +

Our licenses are + irrevocable. Licensors should read and understand the terms + and conditions of the license they choose before applying it. + Licensors should also secure all rights necessary before + applying our licenses so that the public can reuse the + material as expected.

If + the licensor's permission is not necessary for any reason--for + example, because of any applicable exception or limitation to + copyright--then that use is not regulated by the license.

A licensor may make special requests, + such as asking that all changes be marked or described. + Although not required by our licenses, you are encouraged to + respect those requests where reasonable. More considerations + for the public: + wiki.creativecommons.org/Considerations_for_licensees + +======================================================================= + +Creative Commons Attribution 4.0 International Public License + +By exercising the Licensed Rights (defined below), You accept and agree +to be bound by the terms and conditions of this Creative Commons +Attribution 4.0 International Public License ("Public License"). To the +extent this Public License may be interpreted as a contract, You are +granted the Licensed Rights in consideration of Your acceptance of +these terms and conditions, and the Licensor grants You such rights in +consideration of benefits the Licensor receives from making the +Licensed Material available under these terms and conditions. + + +Section 1 -- Definitions. + + a. Adapted Material means material subject to Copyright and Similar + Rights that is derived from or based upon the Licensed Material + and in which the Licensed Material is translated, altered, + arranged, transformed, or otherwise modified in a manner requiring + permission under the Copyright and Similar Rights held by the + Licensor. For purposes of this Public License, where the Licensed + Material is a musical work, performance, or sound recording, + Adapted Material is always produced where the Licensed Material is + synched in timed relation with a moving image. + + b. Adapter's License means the license You apply to Your Copyright + and Similar Rights in Your contributions to Adapted Material in + accordance with the terms and conditions of this Public License. + + c. Copyright and Similar Rights means copyright and/or similar rights + closely related to copyright including, without limitation, + performance, broadcast, sound recording, and Sui Generis Database + Rights, without regard to how the rights are labeled or + categorized. For purposes of this Public License, the rights + specified in Section 2(b)(1)-(2) are not Copyright and Similar + Rights. + + d.

Share means to provide material to the public by any means or + process that requires permission under the Licensed Rights, such + as reproduction, public display, public performance, distribution, + dissemination, communication, or importation, and to make material + available to the public including in ways that members of the + public may access the material from a place and at a time + individually chosen by them. + + j. Sui Generis Database Rights means rights other than copyright + resulting from Directive 96/9/EC of the European Parliament and of + the Council of 11 March 1996 on the legal protection of databases, + as amended and/or succeeded, as well as other essentially + equivalent rights anywhere in the world. + + k.

The + Licensor authorizes You to exercise the Licensed Rights in + all media and formats whether now known or hereafter created, + and to make technical modifications necessary to do so. The + Licensor waives and/or agrees not to assert any right or + authority to forbid You from making technical modifications + necessary to exercise the Licensed Rights, including + technical modifications necessary to circumvent Effective + Technological Measures.

Offer from the Licensor -- Licensed Material. Every + recipient of the Licensed Material automatically + receives an offer from the Licensor to exercise the + Licensed Rights under the terms and conditions of this + Public License. + + b. No downstream restrictions.

Moral rights, such as the right of integrity, are not + licensed under this Public License, nor are publicity, + privacy, and/or other similar personality rights; however, to + the extent possible, the Licensor waives and/or agrees not to + assert any such rights held by the Licensor to the limited + extent necessary to allow You to exercise the Licensed + Rights, but not otherwise. + + 2. Patent and trademark rights are not licensed under this + Public License. + + 3. To the extent possible, the Licensor waives any right to + collect royalties from You for the exercise of the Licensed + Rights, whether directly or through a collecting society + under any voluntary or waivable statutory or compulsory + licensing scheme. In all other cases the Licensor expressly + reserves any right to collect such royalties. + + +Section 3 -- License Conditions. + +Your exercise of the Licensed Rights is expressly made subject to the +following conditions. + + a. Attribution. + + 1. If You Share the Licensed Material (including in modified + form), You must: + + a. retain the following if it is supplied by the Licensor + with the Licensed Material: + + i. identification of the creator(s) of the Licensed + Material and any others designated to receive + attribution, in any reasonable manner requested by + the Licensor (including by pseudonym if + designated); + + ii. a copyright notice; + + iii. a notice that refers to this Public License; + + iv. a notice that refers to the disclaimer of + warranties; + + v. a URI or hyperlink to the Licensed Material to the + extent reasonably practicable; + + b. indicate if You modified the Licensed Material and + retain an indication of any previous modifications; and + + c. indicate the Licensed Material is licensed under this + Public License, and include the text of, or the URI or + hyperlink to, this Public License. + + 2. You may satisfy the conditions in Section 3(a)(1) in any + reasonable manner based on the medium, means, and context in + which You Share the Licensed Material. For example, it may be + reasonable to satisfy the conditions by providing a URI or + hyperlink to a resource that includes the required + information. + + 3.

This is the entry point for an admin's triage; it +names the next skill instead of diagnosing a single workload or node. + +**Read-only:** inspect and report only.

If it is not installed, +give a short read-only answer to the narrow question from the MCP tools that +answer it directly (usually one or two calls), and say which skill would give +the full answer. Write requests are the exception: make zero MCP calls. + +- Quota fairness, starved vs over-borrowing projects, reclaim → + `runai-audit-assigned-quota`. +- Which teams or projects hold GPUs without using them → + `runai-get-utilization-overview`. +- One workload's health, a filtered workload list, or "several workloads + failed — is this a node issue?" → `runai-get-workload-health-summary`. +- Why one workload failed → `runai-diagnose-failed-workload`; why one workload + is pending → `runai-diagnose-pending-workload` when available. +- GPU errors, XID, thermal, or NVLink problems on a specific node → + `runai-diagnose-node-health` when available. +- History or trends ("GPU failures last week") → say the health verdict is + point-in-time and failure history is not available. Offer + `get_cluster_metrics` with `window="last_7d"` (`totalGpu`, `allocatedGpu`, + `gpuUtilization`) as a capacity trend, and never invent failure counts. +- Cordon, drain, restart, delete, or rebalance requests → make zero MCP calls + and run no commands. State: "No action will be taken without explicit + confirmation in a separate write-capable workflow." If the request rests on + an unverified premise, such as cordoning the only GPU node in a pool, point + out the impact first. + +## Prerequisites + +- **Run:ai MCP server, required**, with read access to node pools, node health, + cluster inventory, cluster metrics, workload counts, workload lists, + workload status, workload specs, and workload history. +- **No Kubernetes access is used.** The skill is MCP-only by design. If the MCP + is unavailable, say so and stop; do not fall back to `kubectl` and do not + estimate numbers. + +## Parameters + +| Input | Required | Default | Notes | +| --- | --- | --- | --- | +| `cluster_id` | Yes | — | Cluster UUID. See Stage 1 to resolve it. | +| `node_pool` | No | all pools | Scope the health and inventory calls to one pool (Stage 2). | +| `pending_threshold` | No | `15m` | A pending workload counts only after this wait. | +| `pending_sample` | No | `5` | Oldest pending workloads to inspect. | + +## Tools + +| Tool | Use | +| --- | --- | +| `list_node_pools` | Pool identity, default pool, and `phase`. Without `clusterId` it lists pools across clusters — use it to resolve the cluster. | +| `get_cluster_infrastructure_health` | NotReady/Unknown nodes, their conditions, taints, GPU counts, `gpusUnschedulable` per pool. | +| `get_cluster_physical_inventory` | Per pool: `gpusTotal`, `gpusAllocatable` (on Ready nodes), `gpusAllocated`, `gpusFree`. | +| `get_workloads_summary` | Cluster-wide phase counts: `pending`, `failed`, `running`. | +| `get_cluster_metrics` | Cluster-wide GPU utilization and allocation series for the last hour. Never pass `nodePoolName`. | +| `list_workloads` | The oldest pending workloads, with requested pools and GPUs. | +| `get_workload_status` | `phaseMessage`, `phaseReason`, conditions, and events for one pending workload. | +| `get_workload_spec` | Placement of a pending workload (`nodeType`, affinity, pools) when its request fits the free GPUs. | +| `get_workload_history` | Older events of that workload, to prove a placement mismatch the newest events no longer show. | + +## Instructions — workflow + +### Stage 1 — Preflight gates + +Apply in order. A stop means no further MCP calls. + +1. **Route out** anything in "When not to use", as that section describes. Do + not load or run the other skill in the same turn. +2. **Resolve the cluster.** If the user gives a cluster UUID, use it. If not, + call `list_node_pools` without `clusterId` and read the distinct + `clusterId` values: exactly one → use it and say so; more than one → list + them and ask which cluster, then stop. + +### Stage 2 — Collect the snapshot + +Call these four in parallel with `clusterId`. When the user named a pool, also +pass `nodePoolName`, but only to `get_cluster_infrastructure_health` and +`get_cluster_physical_inventory`; `list_node_pools` rejects it: + +1. `list_node_pools` — pool `phase` and which pool `isDefault`. +2. `get_cluster_infrastructure_health` — unhealthy nodes per pool. +3. `get_cluster_physical_inventory` — GPU capacity and allocation per pool. +4. `get_workloads_summary` — **cluster-scoped only, never `nodePoolName`**: + pending workloads have no pool assignment yet, so a pool filter hides them. + +Then call `get_cluster_metrics` once with `window="last_1h"`, +`metricTypes=["gpuUtilization","allocatedGpu","totalGpu"]`, and +`numberOfSamples=12`. Never pass `nodePoolName`: the current server returns +cluster-wide allocation and utilization for every pool. When the user asks +for utilization per pool, give allocation per pool from the inventory and the +cluster-wide utilization, and name `runai-get-utilization-overview` for +utilization per pool. If the user asks for a metric +this list omits (for example `avgWorkloadWaitTime`), request it too. If +`partialData` is true or a series is missing, name each missing metric as +unavailable. Never compute or estimate a missing series, and never invent +scheduling wait times. + +Use the `asOf` value of the health response as **now** for every duration. + +### Stage 3 — Sample the pending backlog + +Skip this stage when the summary reports zero pending workloads. + +1. Call `list_workloads(clusterId, phase="Pending", + sortBy="totalPendingTimeSeconds", sortOrder="desc", limit=pending_sample, + includeDetails=true)`. One page only; this is a sample, not an inventory. + Older MCP servers reject `includeDetails`; if so, call it again without + that argument and attribute each row to the pool named in its status + message, or else the default pool, and say so. +2. For each row, `wait = now − phaseUpdatedAt`. Ignore rows with + `wait < pending_threshold`. +3. Attribute each row to its `requestedNodePools`; with none, use the default + pool. +4. Call `get_workload_status` for each remaining row and classify it: + +| Class | Rule | Effect | +| --- | --- | --- | +| `SPEC` | `phaseMessage`, `phaseReason`, a condition, or **any** event (not only the newest) names a workload-side block: node selector or affinity with no match, quota exceeded for non-preemptible work, image, volume, policy. | Not a cluster fault. Report it and route (Hand-off). | +| `CAPACITY` | Not `SPEC`, and every requested pool has `gpusFree < requestedGpu`; or a not-enough-resources reason is reported. | Pool is full. Not a fault. | +| `SCHEDULER_SUSPECT` | Not `SPEC`, no reason reported, and a requested pool has `gpusFree >= requestedGpu` (or `gpusFree > 0` when `requestedGpu` is null). | Free GPUs are not being scheduled. | +| `UNCLASSIFIED` | None of the above, for example `requestedGpu` is null, the requested pools have no free GPUs, and no reason is reported. | GPU demand unknown. Report it with its wait; no verdict effect. | + +Read every returned event with its timestamp, not only the newest: + +- A node selector or affinity mismatch in any event makes the workload `SPEC`, + even when newer events name only missing GPUs. Once the pool is full, the + scheduler reports the GPU shortage first and stops naming the mismatch. +- An admission, device, or webhook error older than the workload's newest + scheduling event is history, for example from a node or control-plane + restart. It never makes the workload `SPEC`, even when it names a quota or + policy. Never report it as a current GPU or scheduler fault; if you mention + it, call it an earlier event. + +When a not-enough-resources reason appears although a requested pool has +`gpusFree >= requestedGpu`, call `get_workload_spec` for that workload first. +If its spec pins placement (`nodeType`, `nodeAffinityRequired`, or +`podAffinity`), look for proof that the pin matches no node: an event saying a +node selector or affinity did not match. The newest events often name only the +GPU shortage, so when the status events do not show it, call +`get_workload_history` for that workload with `limit=50` and read its older +events. A retrying scheduler logs a shortage event on every retry, so if no +mismatch event appears and the response has `next`, follow it, up to 3 pages. + +- A mismatch event found → class it `SPEC` and name the pin. +- No mismatch event → keep `CAPACITY`, and name the pin as a possible cause the + tools cannot confirm: node labels are not exposed, and the pinned nodes may + simply be full. + +Without a pin, keep `CAPACITY` and name the possible cause from the +evidence, never as fact: + +- More than one GPU node in the pool (`gpuNodes > 1`): free GPUs can be split + across nodes, so a multi-GPU request may not fit on any one node. +- One GPU node: GPUs can be held outside Run:ai accounting, for example by + fractional or non-Run:ai pods. Point to it when the latest GPU utilization + times `gpusTotal` is higher than `gpusAllocated`. + +Always state "sampled N of M pending", where M is the cluster-wide pending +count from `get_workloads_summary`. + +### Stage 4 — Verdict per pool + +The worst matching row sets the pool verdict. The cluster verdict is the worst +pool verdict. + +| Verdict | Any one of these in the pool | +| --- | --- | +| `STUCK` | 1+ `SCHEDULER_SUSPECT` workload; or `phase` is `Unschedulable`; or GPU nodes exist (`gpusTotal > 0`) but `gpusAllocatable == 0`. | +| `DEGRADED` | `gpusUnschedulable > 0`; or 1+ `CAPACITY` workload; or `phase` is `Creating`, `Updating`, or `Deleting`. | +| `HEALTHY` | None of the above. | + +Notes that never change a verdict: + +- A NotReady node **without GPUs** is a note on its pool. +- A pool with `phase` `Empty` has no nodes; it is a note, not a fault. +- `SPEC` pending is a workload problem, not a pool problem. +- `UNCLASSIFIED` pending is reported with its wait but never sets a verdict. +- Utilization and failed-workload counts are context. +- A taint such as `runai=drain` or a cordon condition on an unhealthy node + means the outage can be intentional maintenance; say so. + +### Stage 5 — Compose the answer + +Keep it to one screen. When the question is narrow (only nodes, one pool, only +utilization), answer that first, then give the verdict line; omit sections the +question does not need, except Failures and Next. + +1. **Line 1:** `: ` with `asOf`, then the dominant blocker in + one sentence (the worst pool's reason). +2. **Pool table:** pool, verdict, unhealthy nodes, GPUs + `allocated/allocatable/total`, `gpusFree`, sampled pending by class, and + the blocker. +3. **Scheduler:** for each pool with pending demand, say `STUCK` (free GPUs + not scheduled) or full (`CAPACITY`) — never call a full pool stuck. +4. **Nodes:** each unhealthy node with status, condition reason, GPUs, and pool. +5. **Utilization:** cluster GPU allocation and 1-hour average GPU utilization, + or "unavailable" with the reason. +6. **Failures:** the cluster `failed` count; if non-zero, route node + correlation to `runai-get-workload-health-summary`. Keep this line in + pool-scoped answers too. +7. **Next:** the specific hand-off for each blocker, naming **every** + `SCHEDULER_SUSPECT` workload ID. + +These statements are mandatory when they apply: + +- The user asks about saturation, capacity, free GPUs, or utilization: also + give the pending backlog (count and sampled classes). A pool with blocked + pending work is not "not saturated", whatever its utilization. +- The user refers to a past event or asks whether something recovered: say the + verdict is a point-in-time snapshot and the skill cannot tell when nodes + failed or recovered. +- The user asks whether GPUs are failing or healthy: say that MCP node health + cannot see a failing GPU on a Ready node, route GPU-level checks to + `runai-diagnose-node-health`, and never state that the GPUs are healthy. + +## Hand-off + +- `SCHEDULER_SUSPECT` workload → `runai-diagnose-pending-workload` with its ID + when available; otherwise give the workload ID and say the scheduler logs + are the next evidence. +- `SPEC` or `UNCLASSIFIED` workload → `runai-diagnose-pending-workload`; quota + reasons → `runai-audit-assigned-quota`. +- Unhealthy GPU node, or a suspected bad GPU on a Ready node → + `runai-diagnose-node-health` when available. +- Failed workloads near an unhealthy node → `runai-get-workload-health-summary`. +- Full pools and over-quota borrowing → `runai-audit-assigned-quota`. + +`HEALTHY` is a complete answer. Do not hand off when nothing is wrong. + +## Examples + +These use invented names; they are not taken from any test data. + +### Stuck cluster + +```text +: STUCK (as of 09:10Z) — pool-c has 6 free GPUs but 1 workload has waited 52m with no reason. + +| Pool | Verdict | Unhealthy nodes | GPUs alloc/allocatable/total | Free | Pending (sampled) | Blocker | +| ------ | -------- | --------------- | ---------------------------- | ---- | ------------------- | --------------------------- | +| pool-c | STUCK | 0 | 2/8/8 | 6 | 1 SCHEDULER_SUSPECT | free GPUs not scheduled | +| pool-a | DEGRADED | 1 (NotReady) | 12/12/16 | 0 | 2 CAPACITY | 4 GPUs lost; pool full | +| pool-b | HEALTHY | 0 | 3/8/8 | 5 | — | — | + +Scheduler: pool-c STUCK; pool-a is full, not stuck.

+Point-in-time Run:ai cluster and node-health check that returns a HEALTHY, DEGRADED, or STUCK verdict per node pool with the dominant blocker (NotReady nodes, offline or failing GPU capacity, GPU counts, allocation vs utilization, the pending backlog, and a stuck scheduler vs a full pool), using read-only Run:ai MCP tools.
+ +This skill is ready for commercial/non-commercial use.
+ +## Owner +NVIDIA
+ +### License/Terms of Use:
+Apache 2.0 AND CC-BY-4.0
+## Use Case:
+Run:ai cluster administrators and platform engineers use this skill to triage whether a cluster is healthy and what blocks each node pool right now, separating a stuck scheduler from a full pool and naming the next skill to hand off to, without making any changes to the cluster.
+ +### Deployment Geography for Use:
+Global
+ +## Requirements / Dependencies:
+**Requires API Key or External Credential:** [Yes]
+**Credential Type(s):** [OAuth Token]
+ +Do not include secrets in prompts/logs/output; use least-privilege credentials; rotate keys as appropriate.
+ +## Known Risks and Mitigations:
+Risk: Review before execution as proposals could introduce incorrect or misleading guidance into skills.
+Mitigation: Review and scan skill before deployment.
+ +## Reference(s):
+ + +## Skill Output:
+**Output Type(s):** [Analysis, API Calls]
+**Output Format:** [Markdown with a verdict line, a per-pool table, and short Scheduler, Nodes, Utilization, Failures, and Next sections]
+**Output Parameters:** [1D]
+**Other Properties Related to Output:** [Read-only; kept to one screen; point-in-time snapshot anchored to the health response asOf timestamp; pending backlog is sampled (default 5 oldest workloads) and the sample size is stated]
+ +## Evaluation Agents Used:
+- Claude Code (`aws/anthropic/bedrock-claude-opus-5-5`)
+- Codex (`openai/openai/gpt-6.1-sol`)
+ + + +## Evaluation Tasks:
+22 evaluation tasks (15 positive, 7 negative), one attempt per task, each run with and without the skill in an isolated sandbox pod against replayed Run:ai MCP responses (one live-recorded healthy cluster and one synthetic cluster with one fault per node pool).
+ +## Evaluation Metrics Used:
+Reported benchmark dimensions:
+- Security: Is it safe to use? Checks for unsafe operations, secret leakage, and unauthorized access.
+- Correctness: Is the answer correct? Final-answer correctness against the reference answer.
+- Discoverability: Was the right skill loaded when needed?
+- Effectiveness: Did the skill help complete the task? Equal-weight mean of goal completion and expected workflow adherence.
+- Efficiency: Did it avoid wasted tool calls and token usage? Equal-weight mean of tool-call productivity and token efficiency.
+ +Underlying evaluation signals used in this run:
+- `security`: Unsafe operations, secret leakage, and unauthorized access.
+- `skill_execution`: Whether the expected skill was selected, decoys were avoided, and the workflow executed.
+- `skill_efficiency`: Tool-call productivity.
+- `accuracy`: Final-answer correctness against the reference answer.
+- `goal_accuracy`: Whether the user's goal was achieved.
+- `behavior_check`: Whether the expected workflow behavior was followed.
+- `token_efficiency`: Actual uncached prompt plus completion token usage.

three-tier evaluation checks whether the skill: + +- is safe to use; +- produces correct answers; +- is discovered and activated when needed; +- helps the agent complete the user's goal and expected workflow; and +- avoids wasted skill and tool usage. + +## Results at a Glance + +| Measure | Claude Code (Baseline → Skill Uplift) | Codex (Baseline → Skill Uplift) | +|---|---:|---:| +| Overall |

Efficiency | 94.8% — baseline ran, but no comparable score was available; uplift unavailable | 62.2% — baseline ran, but no comparable score was available; uplift unavailable | + +**How to read this table:** baseline is the same task attempted without the target skill. Scores are rounded to one decimal; threshold-adjacent values use additional precision so their displayed band matches the verdict. Uplift is derived from those displayed scores and shown in percentage points. + +Example: `47.0% → 92.0% (+45.0 points)` means the skill-assisted run scored 92.0%, 45.0 percentage points above its 47.0% no-skill baseline. + +A partial dimension was calculated from only the available configured signals; review the detailed report before relying on it. + +## Token Usage + +Actual Tier 3 execution usage is reported for every observed agent/case pair and both conditions. + +| Agent | Dataset case | With skill | Without skill | Delta | Change | Coverage | +|---|---|---:|---:|---:|---:|---| +| claude-code | All cases | 4,549,377 | 3,294,332 | +1,255,045 | +38.10% | skill 22/22;

Lift is reported as diagnostic evidence and does not override this gate. +- The 50% attempt pass threshold is a separate per-task gate; it is not the dimension pass threshold. +- Effectiveness is the equal-weight mean of goal completion (`goal_accuracy`) and expected workflow adherence (`behavior_check`). +- Efficiency is 50% tool-call productivity (the backward-compatible `skill_efficiency` wire id) and 50% `token_efficiency`. Positive-case skill routing is scored under Discoverability, not Efficiency; a negative case without a routing target is N/A. N/A sources are omitted, remaining weights are renormalized, and the dimension is marked partial. + +Signals present in this run: + +- `security` (Security): unsafe operations, secret leakage, and unauthorized access. +- `skill_execution` (Skill Execution): whether the expected skill was selected, decoys were avoided, and the workflow executed. +- `skill_efficiency` (Tool Productivity): tool-call productivity (legacy wire id; routing is scored under Discoverability). +- `accuracy` (Accuracy): final-answer correctness against the reference answer. +- `goal_accuracy` (Goal Accuracy): whether the user's goal was achieved. +- `behavior_check` (Behavior Check): whether the expected workflow behavior was followed. +- `token_efficiency` (Token Efficiency): actual uncached prompt plus completion usage (50% of Efficiency). + +
+ +## Freshness + +Regenerate this benchmark when the skill, evaluation dataset, target agent/model, evaluator version, environment, or scoring policy changes. diff --git a/skills/runai-get-utilization-overview/LICENSE b/skills/runai-get-utilization-overview/LICENSE new file mode 100644 index 000000000..bed931aa2 --- /dev/null +++ b/skills/runai-get-utilization-overview/LICENSE @@ -0,0 +1,624 @@ +Run:ai GPU Utilization Overview Skill — Dual License +SPDX-License-Identifier: Apache-2.0 AND CC-BY-4.0 + +This skill directory is dual-licensed: + + * Source code — everything under a skill's scripts/ directory (and any other + executable code) — is licensed under the Apache License, Version 2.0. + * Documentation — SKILL.md, references/, and other prose — is licensed under + the Creative Commons Attribution 4.0 International License (CC-BY-4.0). + +Each source file may carry an SPDX-License-Identifier header naming the license +that applies to it.

Licensors should read and understand the terms + and conditions of the license they choose before applying it. + Licensors should also secure all rights necessary before + applying our licenses so that the public can reuse the + material as expected.

To the +extent this Public License may be interpreted as a contract, You are +granted the Licensed Rights in consideration of Your acceptance of +these terms and conditions, and the Licensor grants You such rights in +consideration of benefits the Licensor receives from making the +Licensed Material available under these terms and conditions. + + +Section 1 -- Definitions. + + a. Adapted Material means material subject to Copyright and Similar + Rights that is derived from or based upon the Licensed Material + and in which the Licensed Material is translated, altered, + arranged, transformed, or otherwise modified in a manner requiring + permission under the Copyright and Similar Rights held by the + Licensor. For purposes of this Public License, where the Licensed + Material is a musical work, performance, or sound recording, + Adapted Material is always produced where the Licensed Material is + synched in timed relation with a moving image. + + b.

Copyright and Similar Rights means copyright and/or similar rights + closely related to copyright including, without limitation, + performance, broadcast, sound recording, and Sui Generis Database + Rights, without regard to how the rights are labeled or + categorized. For purposes of this Public License, the rights + specified in Section 2(b)(1)-(2) are not Copyright and Similar + Rights. + + d.

You may satisfy the conditions in Section 3(a)(1) in any + reasonable manner based on the medium, means, and context in + which You Share the Licensed Material. For example, it may be + reasonable to satisfy the conditions by providing a URI or + hyperlink to a resource that includes the required + information. + + 3. If requested by the Licensor, You must remove any of the + information required by Section 3(a)(1)(A) to the extent + reasonably practicable. + + 4. If You Share Adapted Material You produce, the Adapter's + License You apply must not prevent recipients of the Adapted + Material from complying with this Public License. + + +Section 4 -- Sui Generis Database Rights. + +Where the Licensed Rights include Sui Generis Database Rights that +apply to Your use of the Licensed Material: + + a. for the avoidance of doubt, Section 2(a)(1) grants You the right + to extract, reuse, reproduce, and Share all or a substantial + portion of the contents of the database; + + b. if You include all or a substantial portion of the database + contents in a database in which You have Sui Generis Database + Rights, then the database in which You have Sui Generis Database + Rights (but not its individual contents) is Adapted Material; and + + c. You must comply with the conditions in Section 3(a) if You Share + all or a substantial portion of the contents of the database. + +For the avoidance of doubt, this Section 4 supplements and does not +replace Your obligations under this Public License where the Licensed +Rights include other Copyright and Similar Rights. + + +Section 5 -- Disclaimer of Warranties and Limitation of Liability. + + a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE + EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS + AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF + ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, + IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, + WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR + PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, + ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT + KNOWN OR DISCOVERABLE.

WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR + IN PART, THIS LIMITATION MAY NOT APPLY TO YOU. + + c. The disclaimer of warranties and limitation of liability provided + above shall be interpreted in a manner that, to the extent + possible, most closely approximates an absolute disclaimer and + waiver of all liability. + + +Section 6 -- Term and Termination. + + a. This Public License applies for the term of the Copyright and + Similar Rights licensed here. However, if You fail to comply with + this Public License, then Your rights under this Public License + terminate automatically. + + b. Where Your right to use the Licensed Material has terminated under + Section 6(a), it reinstates: + + 1. automatically as of the date the violation is cured, provided + it is cured within 30 days of Your discovery of the + violation; or + + 2. upon express reinstatement by the Licensor. + + For the avoidance of doubt, this Section 6(b) does not affect any + right the Licensor may have to seek remedies for Your violations + of this Public License. + + c. For the avoidance of doubt, the Licensor may also offer the + Licensed Material under separate terms or conditions or stop + distributing the Licensed Material at any time; however, doing so + will not terminate this Public License. + + d. Sections 1, 5, 6, 7, and 8 survive termination of this Public + License. + + +Section 7 -- Other Terms and Conditions. + + a. The Licensor shall not be bound by any additional or different + terms or conditions communicated by You unless expressly agreed. + + b. Any arrangements, understandings, or agreements regarding the + Licensed Material not stated herein are separate from and + independent of the terms and conditions of this Public License. + + +Section 8 -- Interpretation. + + a. For the avoidance of doubt, this Public License does not, and + shall not be interpreted to, reduce, limit, restrict, or impose + conditions on any use of the Licensed Material that could lawfully + be made without permission under this Public License. + + b. To the extent possible, if any provision of this Public License is + deemed unenforceable, it shall be automatically reformed to the + minimum extent necessary to make it enforceable. If the provision + cannot be reformed, it shall be severed from this Public License + without affecting the enforceability of the remaining terms and + conditions. + + c. No term or condition of this Public License will be waived and no + failure to comply consented to unless expressly agreed to by the + Licensor. + + d. Nothing in this Public License constitutes or may be interpreted + as a limitation upon, or waiver of, any privileges and immunities + that apply to the Licensor or You, including from the legal + processes of any jurisdiction or authority. + + +======================================================================= + +Creative Commons is not a party to its public +licenses.

A pure write request gets zero MCP calls and + this sentence: "No action will be taken without explicit confirmation in a + separate write-capable workflow." A request that also asks a read question + ("find the idle notebooks and stop them") gets the read part from this + workflow, then the same sentence for the write part. + +## Prerequisites + +- **Run:ai MCP server, required**, with read access to node pools, project + resources, departments, cluster inventory, org-unit metrics, cluster + metrics, workload lists, and workload metrics. +- **The cluster must collect GPU metrics.** When a utilization series is + missing, the holder is `UNKNOWN`; the skill never estimates it. + +## Parameters + +| Input | Required | Default | Notes | +| --- | --- | --- | --- | +| `cluster_id` | Yes | — | Cluster UUID. See Stage 1 to resolve it. | +| `scope` | No | `project` | `project`, `department`, or `node_pool`. A named project or department is checked on its own. | +| `window` | No | `last_7d` | `last_1h`, `last_24h`, `last_7d`, `last_30d`, or an explicit `start`/`end` range. | +| `well_utilized_threshold` | No | `50` | Average utilization (%) at or above which a holder is `WELL_UTILIZED`. | +| `idle_threshold` | No | `5` | Average utilization (%) below which a holder is `IDLE`. | +| `max_entities` | No | `10` | Holders checked, largest current allocation first. | +| `drill_limit` | No | `10` | Idle workloads listed per drilled project. | + +## Tools + +| Tool | Use | +| --- | --- | +| `list_node_pools` | Resolve the cluster. Without `clusterId` it lists pools across clusters. | +| `list_project_resources` | Current GPU allocation per project per pool: the candidate set. | +| `list_departments` | Current GPU allocation per department: the department candidate set. | +| `get_cluster_physical_inventory` | GPUs per node pool now: which pools have GPUs and how many. | +| `get_org_unit_metrics` | Allocation and utilization series for one project or department, optionally in one pool. | +| `get_cluster_metrics` | Whole-cluster allocation, capacity, and utilization series. Never pass `nodePoolName` (see Stage 3). | +| `list_workloads` | Workloads with idle allocated GPUs right now (`gpuIdleOnly`). | +| `get_workload_metrics` | One workload's utilization series, for named workloads or per-workload history. | + +## Instructions — workflow + +### Stage 1 — Preflight gates + +Apply in order. A stop means no further MCP calls. + +1. **Route out** anything in "When not to use", as that section describes. Do + not load or run the other skill in the same turn. +2. **Resolve the cluster.** If the user gives a cluster UUID, use it. If not, + call `list_node_pools` without `clusterId` and read the distinct + `clusterId` values: exactly one → use it and say so; more than one → list + them and ask which cluster, then stop. +3. **Resolve the scope.** "Projects" and "teams" mean projects; "departments" + or "business units" mean departments; "which pool" means node pools. +4. **Resolve the window.** "Right now" or "last hour" → `last_1h`; "today" or + "last 24 hours" → `last_24h`; no window → `last_7d`; "this month" or "last + 30 days" → `last_30d`. Longer than 30 days ("last quarter") → pass + `start` and `end` (RFC3339) for that period instead of `window`; how far + back data goes depends on the cluster's metrics retention, so report the + coverage. Pick the sample count from this table: + + | Window | `numberOfSamples` (S) | Step | + | --- | --- | --- | + | `last_1h` | 12 | 5 min | + | `last_24h` | 24 | 1 h | + | `last_7d` | 28 | 6 h | + | `last_30d` | 30 | 24 h | + | `start`/`end` beyond 30 days | 30 | range / 30 (about 3 days for a quarter) | + +### Stage 2 — Candidates + +Follow `nextOffset` while `hasMore` on every list call in this stage. + +- **Projects:** call `list_project_resources` with `clusterId` (and + `nodePoolName` when the user named a pool). Sum each cell's allocated GPUs (`allocated` under `gpu`) per + project across pools; cells with `allocated` null or 0 (quota only) do not + count. Before any metric call, write the candidate list sorted by allocated + GPUs, largest first, as `name (GPUs)`. M is the length of that list, + including holders that later turn out `UNKNOWN`. Check the first + `max_entities` (N) in that order; the rest are the unchecked holders. +- **Departments:** call `list_departments` with `clusterId`; candidates have + allocated GPUs (`gpu` under `allocated`) above 0. +- **Node pools:** call `get_cluster_physical_inventory` with `clusterId`; GPU + pools have `gpusTotal` above 0. Call `list_project_resources` with + `clusterId` and group the cells with allocated GPUs by pool and by + `departmentId`. Each (department, pool) pair is one candidate; a project + without a department is its own candidate. +- **A named project or department** is checked even when it holds no GPUs + now; it may have held GPUs earlier in the window. + +### Stage 3 — Series + +Call these in parallel, one per candidate, with +`metricTypes=["gpuAllocation","gpuUtilization","gpuMemoryUtilization"]`, +`window` (or `start` and `end`), and `numberOfSamples=S`: + +- **Projects and departments:** `get_org_unit_metrics` with `orgType`, + `orgId`, and `clusterId`. Add `nodePoolName` when the user named a pool. +- **Node pools:** `get_org_unit_metrics` with `orgType="department"`, the + department's `orgId`, `clusterId`, and `nodePoolName` for each pair. A pool's + series are the sum of its pairs: allocation adds up, and utilization is + `sum(a × u) / sum(a)` per timestamp. + +Do not call `get_cluster_metrics` with `nodePoolName`: the current server +returns cluster-wide allocation, capacity, and utilization for every pool. If +pool series from any source come back identical for every pool, say pool +scoping is unavailable instead of reporting them. + +For a cluster-wide waste total, call `get_cluster_metrics` once with +`clusterId`, `metricTypes=["allocatedGpu","totalGpu","gpuUtilization"]`, the +same `window` (or `start` and `end`) and `numberOfSamples=S` as the holder +calls, without `nodePoolName`. Its +`gpuUtilization` averages over every GPU in the cluster, allocated or not. +Convert each sample to held-GPU utilization: +`u = gpuUtilization × totalGpu / allocatedGpu`. If that exceeds 100, GPUs are +busy outside Run:ai accounting; say so, cap `u` at 100, and read +`references/utilization-accounting.md`. + +Rules for the responses: + +- An error that `GPU_MEMORY_UTILIZATION` is not supported for the cluster + version (clusters before 2.21) → retry the same call without + `gpuMemoryUtilization`, say GPU memory utilization is unavailable on this + cluster version, and skip the memory-loaded flag. +- `seriesTruncated: true` → retry once with half the samples. +- No `gpuUtilization` series → the holder is `UNKNOWN`: report its held GPUs + and say its utilization is unavailable. Never estimate it, and leave it out + of rankings and totals. When `partialData` is true but `gpuUtilization` is + present, classify the holder normally and name the missing metric. +- Points with no data are omitted. Use only timestamps present in both the + allocation and the utilization series. + +### Stage 4 — Compute per holder + +Use the n samples that have allocation `a > 0` and utilization `u`: + +| Value | Formula | +| --- | --- | +| Held GPUs | mean of `a` | +| Utilization avg | `sum(a × u) / sum(a)` (the plain mean of `u` when `a` is constant) | +| Utilization p95 | sort `u` ascending and take the value at rank `ceil(0.95 × n)`; with n < 20 that is the highest sample, so label it `peak` | +| Idle GPUs | `held × (1 − avg / 100)` | +| Idle GPU-hours | `sum(a × (1 − u / 100)) × step hours` | +| Coverage | `n / S`, always shown as `n of S samples` | + +With full coverage, idle GPU-hours equal idle GPUs times the window in hours. +Show utilization with no decimals, GPUs with one decimal, and GPU-hours as +whole numbers prefixed with ≈. Call coverage full only when n equals S. Below +50% coverage, say the holder only has data for part of the window and that +its GPU-hours cover only that part. Never fill the gaps: a missing sample is +no data, not idle time. Then lead with its latest samples (the +`idle since` flag) rather than its average. + +### Stage 5 — Classify + +| Class | Rule | +| --- | --- | +| `LOW_DATA` | fewer than 4 samples (n < 4): report the samples, do not classify, and suggest the shortest window that covers the holding time | +| `IDLE` | avg < `idle_threshold` | +| `UNDER_UTILIZED` | `idle_threshold` ≤ avg < `well_utilized_threshold` | +| `WELL_UTILIZED` | avg ≥ `well_utilized_threshold` | +| `UNKNOWN` | no utilization series | + +Flags that qualify a class, shown in the class column: + +- **bursty:** do not flag it when coverage is below 50% or when the holder is + flagged `idle since`. Otherwise flag it when avg < `well_utilized_threshold` + but p95 ≥ it. The peaks use the GPUs; + say "bursty, not idle", and never suggest it gives up all its GPUs. It needs + at least 2 samples, and at least 10% of n, at or above + `well_utilized_threshold`; one high sample is a spike, not bursts. +- **idle since `
