Description

GPU hardware has many attributes that may impose scheduling constraints (e.g. core count, total memory, topology (via PCI-E, NVLINK, etc), driver versions, etc). Tasks may require a particular card type to run correctly.

With respect to topology, tasks that require access to more than 1 GPU may need to be placed onto NVLink connected GPUs for acceptable performance compared to having to communicate over PCI or QPI.
