Subject: [HTCondor-users] running MPI jobs

Hi All,

We found an interesting phenomenon when running MPI jobs, it seems the processes running on the same machine as the launch process will share one core, not in the way it should be: running on different cores. And other allocated cores are actually idle when condor_status considered them as "busy". The processes mentioned belong to one job. Do we need do some other configurations or anything else to avoid the situation?

Thanks & Regards,

Kathy
