Dear AllI need some help with reading the output of /proc/cpuinfo. We have several machines and they are all supposedly identical Intel Xeon machines. 4 CPUs each and identical Linux version. One of the machines are reporting VERY high load consistently. They are all running identical applications and I don't see any difference in load. However, when I look at /proc/cpuinfo, this "very high load" box is saying: apicid : 25 initial apicid : 25 All the other machines are reporting 4 for this number. Does it matter what this number say? I looked online but cannot quite tell whether it matters or not. thanks -v _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
the apicid might be unrelated to what you are troubleshooting. My understanding is that it's an identifier used to keep track of logical cores.
If this number is the same on all your other systems then all that says is that this CPU might be from a different lot.
It could also suggest a difference in microcode, or BIOS firmware, which you can identify through more effective means.
I would compare some of the other details, such as the various levels of firmware that govern software->hardware interactions. Maybe this box is running a different spectre mitigation?
