GPU Node topology / Interconnect #74

Open ptheywood opened 2 years ago

It may be useful to provide more detail on the different nodes in bede, including Nvlink topology for instance.

Some of this information is present in various PDFs on the N8 website but may be partially incorrect for Bede specifically.

This would be most appriate to be put on hardware/, with a section on the topology of the gpu nodes (nvlink between all gpus, and 2 gpus per cpu), and a section on infer nodes (no nvlink?, unsure on CPU->GPU connections, probably 2 per cpu on the same PCI-e switch?)
