Performance guide is unspecified

The new GPUDirect/NCCL guidance points readers to “redhat documentation” without a link or document title. Readers must search for the intended instructions themselves and may choose a guide that does not match their setup. Link directly to the relevant Red Hat guide.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!
