Hi Bernhard, > $ gfortran -o omp -fopenmp omp.f90 -static -Wl,--whole-archive -lpthread > -Wl,--no-whole-archive && OMP_NUM_THREADS=2 ./omp
that does indeed do the trick! As suggested in your other mail, I should ask Jakub for his opinion. (Statically compiling/linking on the same machine with the Intel compiler seems to simply work without similar issues. ) Thanks, Harald
