Hi,
Windows server should be able to support multiple Tesla cards as long as the hardware supports. And from HPC Pack side, we don't have limitation on the GPU number per node. And we do have customers with multiple GPU per HPC node configuration and
use subscribed socket to do job resource allocation (By setting subscribed sockets, you can have same number of sockets and GPU on one node, and your GPU job can ask resources in socket).
And we are also looking into GPU support enhancement in HPC pack, if you have requirements, please let us know through
