Hi Hamid Rez Khaleghzadeh,
I was interested in the same information a few days ago. I read this
article that made the issue clear for me.
http://developers.sun.com/solaris/articles/solaris_processor.html
To summarise the article into the information that you are after.
The processor_bind will set an process/thread to run on a processor, but
other processes/threads may utilise that processor. The pset_bind will
only allow processes/threads that you specify using the pset_bind to run
on the processors specified within the "processor set" that you
allocated. So pset_bind, used correctly, can be used to both stop a
thread from being migrated and to prevent thread interference.
There is an limitation in pset_bind that you cannot allocate processor
0, whereas processor_bind will allow you to allocate processor 0.
Hope that helps.
Regards,
John

can do it? Do I use pset_bind or processor_bind?
