Regarding the determinism: Intel ArBB is reproducing the exact same results of a computation on a particular machine/processor regardless of how many threads are used. Intel ArBB is utilizing work-stealing which is generating the same number of partitions regardless of the number of actual cores or threads. Because of this, e.g. even numerical errors are reproduced independent of the number of cores working on a certain problem.
