And it's my understanding that - apart from hyperthreading and some types of architecture where memory is partitioned by processor core - it's usually best to let the process scheduler make its own mind up - linux process schedulers usually try hard to keep threads running in the same core anyway. The point being that if you rely on fixed affinity and some idiot tries to run two compute-bound processes on the same core then you can end up with a system with a long compute queue but with significant amounts of totally wasted cpu cycles.
