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 0-3 on one side and 8-11 on the other side, and NUMA 1 be replaced with two NUMA nodes with processors 4-7 and 12-15 respectively. Your grep for SRAT confirms that there are 4 NUMA nodes in the machine, and the APIC numbers seem correctly associated. Unfortunately, it looks like you have the last BIOS revision (1.01) http://www.tyan.com/support_download_bios.aspx?model=B.YR190B8238 Is there any kernel update available from RHEL6 for your machine?
