[mpich-discuss] questions about cpu assign in windows

[Jayesh Krishna]

Hi,
 When your launch your MPI job, the process manager creates the MPI processes and the OS schedules these processes (By default processes are not bound to a core. The OS scheduling policy decides on it).
 You can explicitly specify the binding policy using the "-binding" option of mpiexec on Windows (Refer to Section 9.6 of the Windows developers guide available at http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs for details).

Regards,
Jayesh

hi 
I am new to MPICH, now I face up with a problem. 
I can't get the info. about which cpu ( or computer, node) does the process excute in when I use mpi. 
I read the material about it , it says "MPI is a clean interface , didn't offer the resource management interface" so can I think it means that ,if I want to know the info as I said before, I need to install another software to gain my ends. 
My operating system is WindowsXP, so I can't use taskset. Can you give me some advices? 
thanks 
Yao
