It could mean one 8-core CPU, a pair of 4-core CPU's, four 2-core CPU's, or 8 1-core CPU's. Cores are counted individually. If you care which belongs in what chip, that's the physical ID.
If you just care about the number of cores, counting the line match like that will work fine.
In fact, you don't need to even match anything. Just count the number of records, splitting on blank lines, by setting RS to "". Then when awk runs out of input, print NR, the number of records. On my dual-core system:
hi,
i want to know cpu utilizatiion per process per cpu..for single processor also if multicore in linux ..to use these values in shell script to kill processes exceeding cpu utilization.ps (pcpu) command does not give exact values..top does not give persistant values..psstat,vmstat..does njot...

Hello Friends,
On one of my Solaris 10 box, CPU usage shows 100% using "sar", "vmstat". However, it has 4 CPUs and prstat and glance are not showing enough processes to justify high CPU utilization.

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)
I have a number of LPARs on one P520. All LPARs are running 5.3 and I observe the following:
On some LPARs the number of CPUs found do not match between topas and mpstat.

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)
We have a single threaded application which is restricted by CPU usage even though there are multiple CPUs on the server, hence leading to significant performance issues. Is it possible to merge / combine multiple CPUs at OS level so it appear as a single CPU for the application? (6 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)
I read that Entitlement CPU should be set to max 75% compare to Virtual CPU. May I know the reason.
I have set the Entitlement CPU = Virtual CPU on AIX . It works fine .
Can you help to understand. (1 Reply)

CPUPOWER-FREQUENCY-INFO(1) cpupower Manual CPUPOWER-FREQUENCY-INFO(1)NAME
cpupower frequency-info - Utility to retrieve cpufreq kernel information
SYNTAX
cpupower [ -c cpulist ] frequency-info [options]
DESCRIPTION
A small tool which prints out cpufreq information helpful to developers and interested users.
OPTIONS -e --debug
Prints out debug information.
-f --freq
Get frequency the CPU currently runs at, according to the cpufreq core.
-w --hwfreq
Get frequency the CPU currently runs at, by reading it from hardware (only available to root).
-l --hwlimits
Determine the minimum and maximum CPU frequency allowed.
-d --driver
Determines the used cpufreq kernel driver.
-p --policy
Gets the currently used cpufreq policy.
-g --governors
Determines available cpufreq governors.
-a --related-cpus
Determines which CPUs run at the same hardware frequency.
-a --affected-cpus
Determines which CPUs need to have their frequency coordinated by software.
-s --stats
Shows cpufreq statistics if available.
-y --latency
Determines the maximum latency on CPU frequency changes.
-o --proc
Prints out information like provided by the /proc/cpufreq interface in 2.4. and early 2.6. kernels.
-m --human
human-readable output for the -f, -w, -s and -y parameters.
REMARKS
By default only values of core zero are displayed. How to display settings of other cores is described in the cpupower(1) manpage in the
--cpu option section.
You can't specify more than one of the output specific options -o -e -a -g -p -d -l -w -f -y.
You also can't specify the -o option combined with the -c option.
