[Fernando Boza]

When I execute gzip it run on all processor.... is possible execute it on only two processors?

Fernando,

Check out "man mpsched".

http://docs.hp.com/en/B2355-90689/mpsched.1.html

If there are questions after reading that please do not hesitate to ask again with specifics.

hth,

I wasn't aware gzip was multithreaded, so it would run on one processor at a time.

This indicates you have 13 gzip processes (3 sleeping) and 16 CPUs.

Any reason you want to limit it to two CPUs?
It would probably be better to limit the number of gzip processes or nice them.

Hi,

It is possible using mpsched as well as the new concept called wlm(Work Load Manager) and PRM(Process Resource Manager)in which we can assign even the "%" of CPU to a perticular process.This means only that much of share of CPU will be utilized by Perticular process.
