[mpich-discuss] Affinity mapping with MPICH progress thread

[Tareq Malas]

Hello,

I am looking for a relatively simple way to control the affinity mapping of
the MPICH progress thread and the other threads of my application. In
particular, I am using a cluster that has dual 8-core Intel Sandy Bridge
sockets per node. I would like to assign the progress thread to a singe
core and use the other cores to run my application. Is there a way to pin
or detect which core is assigned to the progress thread? I am using
MVAPICH2 version 1.9a2 built with icc version 13.1.0 (gcc version 4.4.7
compatibility). I am already using MPICH_ASYNC_PROGRESS variable, but I am
not sure how can I combine this with thread affinity mapping library.


Thank you.

Best regards,
Tareq Malas
