We are running EPYC 7451 and 7702 nodes. I do not recall that CentOS 6
was able to support these. We moved on to CentOS 7.6 at first and are
now running 7.7 to support the EPYC2/Rome nodes. The kernel in earlier
releases did not support x2APIC and could not handle 256 threads. Not
and issue on EPYC/Naples, but it was an issue on dual 64 core EPYC2.
Redhat lists 7.4 as the minimum for EPYC(Naples) support and 7.6.6 for
EPYC2(Rome).

We just added about a dozen nodes to our cluster, which have AMD EPYC
7281 processors. When a particular users jobs fall on one of these
nodes, he gets these error messages:
--------------------------------------------------------------------------
WARNING: a request was made to bind a process. While the system
supports binding the process itself, at least one node does NOT
support binding memory to the process location.
Node: dawson205
I wonder if the CentOS 6 kernel properly supports these recent
processors. Does lstopo show NUMA nodes as expected?
Brice
lstopo shows different numa nodes, and it appears to be correct, but I
don't use lstopo that much, so I'm not 100% confident that what it's
showing is correct. I'm at about 98%.
