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.
Maybe I need to add kernel option in /etc/system ?
Thanks

Hi,
what is concept of core in ibm platform?
I want to know how to find out no of core in cpu in aix i.e command
how to find out value of core?
Wheather any specification is there? (1 Reply)
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 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)

psrset
PSRSET(8) BSD System Manager's Manual PSRSET(8)NAME
psrset -- control processor sets
SYNOPSIS
psrset [setid ...]
psrset -a setid cpuid ...
psrset -b setid pid ...
psrset -c [cpuid ...]
psrset -d setid
psrset -e setid command
psrset -i [setid ...]
psrset -p
psrset -r cpuid ...
psrset -u pid ...
DESCRIPTION
The psrset command can be used to control and inspect processor sets.
The system always contains at least one processor set: the default set. The default set must contain at least one online processor (CPU) at
all times.
Available options:
-a Assign one or more processors (CPUs) to the set setid. In the current implementation, a CPU may only be present in one set. CPU IDs
are as reported and used by the cpuctl(8) command.
-b Bind one or more processes to the set setid. All LWPs within the processes will be affected. Bindings are inherited when new LWPs
or processes are forked. However, setting a new binding on a parent process does not affect the bindings of its existing child pro-
cesses.
-c Create a new processor set. If successful, the ID of the new set will be printed. If a list of CPU IDs is provided, those CPUs will
be assigned to the set upon creation. Otherwise, the set will be created empty.
-d Delete the processor set specified by setid. Any LWPs bound to the set will be re-bound to the default processor set.
-e Execute a command within the processor set specified by setid.
-i List all processor sets. For each set, print the member CPUs. If psrset is run without any options, it behaves as if -i were given.
-p List all CPUs. For each CPU, print the associated processor set.
-r Remove a CPU from its current set, and return it back to the default processor set.
-u Bind the specified processes to the system default processor set.

The psrset command first appeared in NetBSD 5.0.
