Sorry for the delay in replying; I've been at an MPI conference and a
follow-on OMPI engineering meeting -- the mail has piled up on me...

The command line syntax of plpa-taskset is pretty weird, mainly
because it's derived from taskset's command line syntax. I think you
need to do the following:

plpa-taskset --pid --cpu-list self

Specifically, the usage is:

usage: plpa-taskset [options] [mask | cpu-list] [pid | cmd [args...]]

So note that --pid does not take any arguments; the pid list ("self",
in this case), needs to go at the end of the command line.

Let me know if that works for you.

This is the best place to report bugs.
