Changed global load balancing to require only a single iteration - still buggy though
default send for assert=yes is now mpi_issend, added minimum load to avoid problems with empty load, still not working though in case of exact matches
Load balancing: All load computation is done in integer arithmetics now, pure MPI appears to work, OpenMP crashes
Load balancing: Fixed OpenMP parallelization
