Openmp in fenics

Hi, Dear fenics users:

I wonder how can I enable the multi-threading in the fenics? parameters[“num_threads”] does not work, export OMP_NUM_THREADS=8 does not speed up either.

Any advise would be appreciated!

Use of concurrent threads has been removed from DOLFIN. Parallelism is provided through separate MPI processes. Looks like you’ve found a legacy option which is no longer supported.
