Sounds like a bug to me, most likely in your code. > Do you think that these small differences are normal? It depends on what small means. Floating point operations in a computer are generally not commutative, so parallelization may in deed lead to different results. > Is there any way to get the same results? is some align problem? Impossible to say without knowing your code.
