Thanks a lot for good vedio. It helps a lot to understand FreeFEM++ in parallel computation!

Great video and I learned a lot from it. Keep up the good work. Also, It would be quite helpful if you make a video on how to properly install MPIs like OpenMPI.

Is it normal to have a big overhead when running with MPI?

No, it usually indicates a problem in MPI installation or using incorrect MPI binaries.

Hi and thank you I'm using virtualbox to emulate Ubuntu 18.04. I haven't had any problems before, however now that I want to use MPI I can't use all the available CPU's because when I use your first example I get this: Process 0 among 1! Process 0 among 1! Process 0 among 1! Process 0 among 1! I am emulating Ubuntu 18.04 it on my computer with 16 cores and I also tried it on my laptop with 4 cores. Could you advise me something to solve it please?

hi, it seems to be a problem with the MPI installation in your system, or a problem in the FreeFEM compilation with the MPI compilers in your system (if you have built it yourself). in this problematic cases, the MPI runtime duplicates the processes instead of parallelizing them, which results to the output you've seen.
