[maint141]

Hi,

Wanted to know in Multi core machine running multiple applications , how to allocate the CPU cores to specific applications.

Thanks in advance.

Hi Varian

Are you asking the commands that manually assigns a CPU core to a specific application ?

I never heard such a thing all I know is that you can use nice command to alter the priority

Are You hinting at Virtualization?

It's the happening technology; and best to make maximum use of Systems Resources

Whole cores or precentages of cores?

Either way, the tool you are looking for is probably Process Resource Manager (PRM):

http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01911854/c01911854.pdf

Us the PRM fair-share-scheduler (FSS) to allocate percentages of CPU to a set of processes, or PRM Processor Sets (PSETs) to allocate whole CPU cores to a set of processes.

good to know

HI All,

Thanks for your replies.
Also wanted to confirm , we can monitor the processor utilization using commands like top, prstat etc & then chnage the processor allocation as per demand.
Is that correct understanding?

Also is it possible to do it in Solaris OS also ?

Look at the various pset_*(2) man pages:
pset_bind(2), etc. psrset(1M)

Hi main141,

On solaris you would achieve this using rpoold (resource pooling). You will be using Fair share scheduler as the default scheduler. It works very well across Solaris zones / containers also.
