Hi Lorenzo,
sorry for my confusing lines. Indeed, I use Open MPI (not OpenMP), so what I did was indeed the following for the building:
export USE_PARALLEL_MINUIT2=1
export USE_MPI=1
but I used cmake, so then I’ll have to probably remake it with configure;make. During the build process
I had to manually go into the minuit folder and give the mpi include path -I/usr/include/openmpi-1.10-x86_64 -pthread -m64
for the g++ build command.
So, indeed previously I did not run it via mpirun. Now after your e-mail running with mpirun -np 8 myprog it does run in multiple processes
and much faster - so I think it works.
Thanks!
Cheers,
Balint
