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)

CORE(5) BSD File Formats Manual CORE(5)NAME
core -- memory image file format
SYNOPSIS
#include <sys/param.h>
DESCRIPTION
A small number of signals which cause abnormal termination of a process also cause a record of the process's in-core state to be written to
disk for later examination by one of the available debuggers. (See sigaction(2).) This memory image is written to a file named by default
core.pid, where pid is the process ID of the process, in the /cores directory, provided the terminated process had write permission in the
directory, and the directory existed.
The maximum size of a core file is limited by setrlimit(2). Files which would be larger than the limit are not created.
The core file consists of the Mach-O(5) header as described in the <mach-o/loader.h> file. The remainder of the core file consists of vari-
ous sections described in the Mach-O(5) header.
NOTE
Core dumps are disabled by default under Darwin/Mac OS X. To re-enable core dumps, a privileged user must do one of the following
* Edit /etc/launchd.conf or $HOME/.launchd.conf and add a line specifying the limit limit core unlimited
* A privileged user can also enable cores with launchctl limit core unlimited
* A privileged user can also enable core files by using ulimit(1) or limit(1) depending upon the shell.
