Re: Using multi-processor for model_free -- September 30, 2016 - 19:24

Sorry, you're right, I re-ran the mpirun -np 5 ./relax --multi="mpi4py" -v
and got no output. So I'm just curious for the other computers I download
openmpi in, just installing it and compiling it isn't enough? There are
some configurations you have to make to have it run on relax?

Sincerely,
Sam
