You're looking for physical id and core id. They both start from zero. I'm looking at a dual quad core system right now. I have 8 entries that look like:
You can also get CPU info with
A quick way to see how many cores total is to run 'top' and then press '1' on your keyboard. That will expand out the processor information at the top and will show you all the cores so you can do a quick count.
how do you cause a running pocess to dump a core file on linux systems??
i tried
sleep 100 &
kill -SEGV PID
but nothing is created
also, what commands can be used to analyze them? (extract useful info from them) (2 Replies)
hi
can i know how to find out basic information about a server
OS version, num of CPU, memory size, SI no.
i ran the comman below...

from this how do i know which version is it in?

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.
