Hello Together,
we are using Microsoft HPC 2012 R2 on our Cluster with enabled Resource Pools.
For us the Calculation of the Cores is unclear.
Following details we can provide: (Shown Values inside HPC Cluster Manager)
Total Weight of the Pool = 1408
Total Current Allocation = 1450
Total Guaranteed Allocation = 1464
When i try to recalculate the Number of Cores, i'm not able to match this numbers:
Following Nodes we have currently Online in this Cluster:
84 x 12 Cores = 1008
50 x 8 Cores = 400
41 x 4 Cores = 164
----------------------
Sum 1572 Cores
Due the Fact, that we use our Nodes with oversubscribed Cores / Sockets
we could also calculate following:
Online Nodes (Oversubscribed Cores=4)
175 x 4 = 700 Cores
Additional to this, we have currently:
3 Nodes which are Offline:
2 x 12 Cores = 24 Cores
1 x 8 Cores = 8 Cores
------------------------
Sum 32 Cores
As you see, We are not able to recalculate the sum of the Total Guaranteed Allocation
1464 Cores.
If we sum up all the real available cores we come to the result of 1572 Cores or
1604 Cores (incl. the Offline ones)
And if we use only the oversubscribed Cores, we come to the result of 708 Cores or
714 Cores (incl. Head Node)
So there is a mismatch of around 140 Cores.
So how is the Total Guaranteed Allocation for the Pool calculated?
We want exactly to distribute the Cores towards the single Pools, but currently it is unclear, how this is managed.
Any explanation about this would be welcome.
Thank you very much in advance,
best regards,
Bobby
