Type of PR:
cleanup / fix issue #484
Description:
The ultimate cause of #484 causing timeouts in the test suite is that we oversubscribe the threads available with MPI+openMP. Hence we now only use 2 openMP threads when running with 4 MPI threads to check the hybrid parallelisation in the test suite.
Testing:
On my laptop, 4 mpi + 4 openMP takes 330s for a test that takes 15s with 4 mpi + 2 openMP threads.
