<div>HI all:</div>
<div> </div>
<div>I noticed that the Intel MPI has the feature about process pinning which avoids the undesired process migration.</div>
<div> </div>
<div>My questions are</div>
<div> </div>
<div>1. Is there a similar way in MPICH2 or I have to use SetProcessAffinityMask() in Windows to pin all my MPI processes to the specific logical processor/core ?</div>
<div> (If a process is pinned to a specific logical processor, the CPU loading histroy from the Windows task manager is smoother rather than lots of zigzags.)</div>
<div> </div>
<div>2. Does the process migration cause large penalty in parallel computing ?</div>
<div> </div>
<div> </div>
<div>Best regards.</div>
