This functionality is available as of 11i with the Processor Sets bundle:

Without that, you can still bind a process to a single CPU with the mpsched command. See the mpsched(1) man page for details.

Steve

hi,

there is no way in hp unix that you can bind any process to perticuler CPU as we can do it in Solaris.

For HP Unix you have to bye a separate product called HP PRM(Process Resource Manager) with the help of PRM you can get this functionality.

HP-UX does support processor affinity, which has 2 levels of binding.

This is not as comprehensive as the processor sets package or PRM.

Man mpctl shows that you can either force a process to be bound to a cpu, or (preferrably) give a process affinity to a cpu, allowing the HP-UX scheduler to override if necessary. You can also discover how many cpus are installed.

See the attached C program which binds a process id (arg 1) to a cpu (arg 2).
