Hello,
We are still researching the possibilities. However, to do this properly can you provide
additional information to clarify? Can you clarify what is meant by coherence as it is referenced in your original post?
Are you using NHM? There is a
formula for NUMA distribution on NMH that might be of interest to you. To determine the NUMA distribution for your
workload:
% Remote Access =
(OFFCORE_RESPONSE_0.DATA_IN.REMOTE_DRAM
/ (OFFCORE_RESPONSE_0.DATA_IN.LOCAL_DRAM + OFFCORE_RESPONSE_0.DATA_IN.REMOTE_DRAM))
* 100
Thanks
