OpenMP

Post by vencels »

In the file ElmerSolver.f90, line 171:

Code: Select all

       ! Set number of OpenMP threads
       nthreads = 1
       !$ nthreads = omp_get_max_threads()
Why OpenMP is disabled in such a way?

Hi

OpenMP is used only in parts of the code and we have struggled yet to find examples where it would beat pure MPI based computation.
