Actually...
Cactus should have also used multiple cores without this change.
Cactus uses OpenMP to run multiple threads even if a single MPI process
is used. You should check the content of the OMP_NUM_THREADS variable.
Also the file ~/simulations/static_tov/output-0000/static_tov_small.out
lists the number of threads used. Something like:

INFO (Carpet): This process contains 1 threads, this is thread 0

Yours,
Roland
