I'm new to the list. This question may have come up before, but I couldn't find an answer to it by searching the centos website. Could be I was using bad keywords for my search. I have 3 HP xw9300 workstations (dual AMD Opteron 64-bit processors) that I'm upgrading from RHEL3WS to CentOS 4.4. I've upgraded two already, with one left to go. On the system with RHEL3WS, 'top' shows statistics for each processor and what processor # each process is running on. On the systems running CentOS 4.4, the output of 'top' looks like that of a uniprocessors system - there are no statistics for each processor and it doesn't show which processor each process is running on. However, /proc/cpuinfo shows the two processors. Does this mean that my OS isn't seeing the second processor, or has the behavior of top changed between the two OS versions? Is there any way that I Can verify that both processors are being used? -- Prentice The contents of this communication, including any attachments, may be confidential, privileged or otherwise protected from disclosure.
