<div dir="ltr">Hello,<div><br></div><div>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.</div>
