[parsec-users] Bind CPUs to threads in SPLASH-2 benchmark

I think that the way you are binding threads is incorrect.  Search in
google for using sched_setaffinity(). See which function in your code
pthreads are calling. In that function you should grab their tid and bind
to sched_setaffinity().  See the man page of sched_setaffinity().
