A wrapper script that takes what is to be executed, check it out and
then dplace it to a certain CPU(s) comes to mind. Since dplace can also
maintain a global count of all active tasks in each CPU that should not
be a problem for you to check out what happens at your end.
If it's not going to be a wrapper script, then that could form part of
your queue system scripts. We handle this issue by placing the dplace
arguments in our PBS scripts.
Maybe someone has a more straightforward solution, but this is what we do.
