[sa-submission-q1-2026] Add numa core binding for all gb200 and gb300 configs

[trevor-m]

Grace-blackwell systems are composed of two numa nodes. Node 0 contains GPUs 0,1 and cpu cores 0-71. Node 1 contains GPUs 2,3 and cpu cores 72-144. Each numa node also has a unified memory between its cpus and gpus. This PR ensures that worker processes are bound to the correct numa node for their gpu that they are assigned to.
