Currently on the cluster we have 3 machines with 40 cores each, while on 2 of those machines we are able to have 40 cores in use, one machine seems "capped" at 20. We have HPC Pack 2012 R2
We have tried to force: Subscribed Cores to 40 and Subscribed Sockets to 2. The most funny thing is that the two machines thare are able to reach 40 Cores in use have a "Subscribed Cores" = 32, Subscribed Sockets = $ null.
To recap this is what we have:
Processors Cores Cores in Use Subscribed Cores Subscribed Sockets
E5-2690 v2 40 40 32
E5-2690 v2 40 40 32
E5-2660 v3 40 20 40 2
As you can see that intel V3 cpu machine based is correctly detected as a 40 Cores machine but the HPC just uses 20.
Is there anything I can do ?
