Info about your CPUs can be optained by
A command for displaying number of cores per CPU does not exist afaik. You have to look this up based on the kind of CPU you are using, power5+ for example etc.
Some info can also be obtained in the 1st lines of lsconf/prtconf.
Also man pages on "lparstat" can be helpful.
After this, reading about SMT (Symetric Multi Threading) will also help.
Hi all.
I've had a quick look around but cant see anything exactly matching my requirements.
I have a new T2000 running S10. Im looking to restrict the no. cores that a S10 non-global zone can use to 1 only. The box is single CPU but 8core.
I want to do this to save on some software... (4 Replies)
Hi Friends-
What does it mean by 2 cpu cores, 3 cpu cores? Does it mean 2 separate cpus or what is it exactly ?
Kindly explain a bit in detail.
Thanks

Hi,
I have 2 physical processor UltraSPARC-T2 with 32 virtual processors
I want to execute a perl program on 10 virtual processors.
I try prset command, but I don't see a difference.
psrset -c "created processor set 2" 1 2 3 4 5 6 7 8 9 10"
psrset -b 2 `pgrep program.pl`

hi all,
I am running SPARC server + solaris 10. (no LDOMs)
Due to change of setup and application licensing cost, I need to cap my core/cpu utilization in my globalzone.
Right now, I have 1x6 cores in my server, how do I change it to utilized 4 cores instead ?
By using... (2 Replies)

lscpu
LSCPU(1) User Manuals LSCPU(1)NAME
lscpu - CPU architecture information helper
SYNOPSIS
lscpu [-hpx] [-s directory]
DESCRIPTION
lscpu gathers CPU architecture information like number of CPUs, threads, cores, sockets, NUMA nodes, information about CPU caches, CPU fam-
ily, model, bogoMIPS, byte order and stepping from sysfs and /proc/cpuinfo, and prints it in a human-readable format. It supports both
online and offline CPUs. It can also print out in a parsable format, including how different caches are shared by different CPUs, which
can be fed to other programs.
OPTIONS -h, --help
Print a help message.
-p, --parse
Print out in parsable instead of human-readable format.
-s, --sysroot directory
Use the specified directory as system root. This allows you to inspect a snapshot from a different system.
-x, --hex
Use hexadecimal masks for CPU sets (e.g. 0x3). The default is to print the sets in list format (e.g. 0,1).
BUGS
The basic overview about CPU family, model, etc. is always based on the first CPU only.
Sometimes in Xen Dom0 the kernel reports wrong data.
