No common random seed on the ranks

Open jeorsch opened this issue 4 years ago • 0 comments

When using --gtest_shuffle no common random seed is guaranteed on the MPI ranks. This leads to funny results. :dizzy_face: One can prescribe such a seed via --gtest_random_seed, but it would be great if that would work automatically. At least an error should be thrown, if --gtest_shuffle is given without --gtest_random_seed and more than one rank is used.
