I'm grading student programs that are multithreaded using OpenMP. They ran timing tests on the MTL. Several of the programs have race conditions. When I run these programs on a processor other than the Xeon Phi the programs produce an incorrect result, as expected. To my surprise, however, they produce a correct result on the Xeon Phi. Can anyone provide any insight to this behavior or point me in the right direction? Thanks! Judy
PS - I guess I should say that I know data races are not deterministic. However, this behavior is very consistent and repeatable. I'm left wondering if maybe something about the Xeon Phi makes it less sensitive to data races. Judy
