Hi,
I would like to clearly understand the output of the mpstat command. What is the mutex spins and also context switches? What if we saw that the number of mutex spins is high. Basically, what to look for in the output of the mpstat command? What is wrong and what is ok. what is the value... (3 Replies)
We have purchased four intels xeon processors
Intel® Xeon® Processor E7530 (12M Cache, 1.86 GHz, 5.86 GT/s Intel® QPI) with SPEC Code(s) SLBRJ
As per the specification each cpu has 6 cores therefore we have 24 cores (considering 4 cpus).
Now how would i calculate the number of vcpus that can... (1 Reply)
Hi,
I am observing high load average on RHEL5 server and need to check the number of core processors available on the box to give me a bigger picture on whether or not I should be worried.
I have always checked the physical count quite simply.....
# grep 'physical id' /proc/cpuinfo |... (10 Replies)
Hello,
sysinfo throws out below 3 CPU counts. Can anyone help me understand what each of these means?
CPU Count Socketed is 2
CPU Count Physical is 8
CPU Count Virtual is 16
First one seems obvious. However, I wonder how there can be 8 Physical CPUs, if... (2 Replies)

have to manually tail the output file and need to grab which cpu has highest value (which is very annoying)
Is there a way we can automate that process of... (3 Replies)

Can someone help me in this. (5 Replies)
seeing weirdness across some 7.1.5.1 LPARs - they all have 2 vCPUs allocated shared. With prtconf they show 2 CPUs, 'lsdev -c processor' concurs, and 'lsattr -El procX' shows that SMT is enabled and there are 2 SMT threads (power5, sorry). Yet running topas on them shows 2 CPUs on some and 4 on... (3 Replies)
