The cluster is running centos6.3 (2.6.32-279.5.2) and will be updated
to the latest centos6.5 (2.6.32-431.3.1) kernel towards the end of next
week. I will reply back to let you know if it worked, thanks very much!

Hello,
Linux says socket 0 contains processors 0-7 and socket 1 contains 8-15,
while NUMA node 0 contains processors 0-3+8-11 and NUMA node 1 contains
processors 4-7+12-15. Given why I read about Opteron 6320 online, the
problem is that NUMA 0 should be replaced with two NUMA nodes with
processors
1) We are getting hwloc topology errors when programs startup on
some new compute nodes added into our cluster recently ...
