Dotfiles

Shell, tmux, and nvim config for NVIDIA Slurm clusters (Lyris: x86 login + aarch64 compute; MARS: aarch64 login + compute; pyxis containers). $HOME is portable across clusters; ~/scratch is cluster-local.

Install

git clone git@github.com:dc3671/dotfiles.git ~/dotfiles
~/dotfiles/install.sh                 # frameworks + symlinks, idempotent
~/dotfiles/install.sh --link-only     # symlinks only (after a $HOME migration)
~/dotfiles/install.sh --tmux-extras   # also fetch tmux net-speed/sysstat

Tool binaries are not installed by the script. Unpack them per arch into $HOME:

Tool	x86_64	aarch64
nvim	~/neovim/bin	~/neovim-aarch64/bin
node	~/node/bin	~/node-aarch64/bin
zsh	~/zsh/bin	~/zsh-aarch64/bin (MARS login; optional)
fzf	nvim lazy dir	~/fzf/bin

Layout

Path	Role
.bash_profile	interactive login outside a job/container: exec this arch's zsh if installed (NOZSH=1 keeps bash); else source .bashrc
.zshrc / .bashrc	framework only (oh-my-zsh + p10k / oh-my-bash + ble.sh), then shell/common.sh
shell/common.sh	env, arch-aware PATH, aliases, ulimit, conda (conda.sh + mamba activate)
.tmux.conf	prefix C-x; boots scripts/claude-hub-boot.sh and scripts/lab-tunnel-boot.sh
tmux/extras.conf	net-speed + sysstat; auto-on only without a cgroup pids cap, TMUX_EXTRAS=1/0 forces
nvim/	lazy.nvim config, plugins pinned in nvim/lazy-lock.json
scripts/	cluster helpers: query_slurm_ppp.sh, get_current_sqsh.sh, check_mem.sh, ssh-reconnect.sh, park_on_lab.sh, update_docker_packages.sh

Conda

CONDA_ENV=<env> picks the env activated in a new shell (incl. pyxis containers); CONDA_ENV=null skips conda; unset activates llm in interactive/login shells only. Miniforge roots: ~/scratch/miniforge3 (aarch64), ~/scratch/miniforge3_x86 (x86).
