Hi,
Thanks for the heads up Joseph, you sent me in the right direction.
Very helpful indeed, although the command that seems to be doing the
trick on my system is
$taskset -c X ...
Best regards,

Still, all eight cores are being used. I can see why you would want

use all cores, and I can see that oversubscribing a sub-set of the
cores might seem silly. My question is, is it possible to do what I
want to do without hacking the open mpi code?
Could you get numactl to help you do what you want? That is, for the
code, somehow tweak the launcher to run
numactl --physcpubind=X ...
or similar?
