Relax can run some [[mpi4py | optimizations]] with multi-processors. [http://www.nmr-relax.com/manual/Usage_multi_processor.html See the manual].<br>
It needs '''openmpi-devel''' and the python package '''mpi4py'''.<br>NOTE, this is not an necessity to run relax, and should only be tried if large number analysis would be tried out.
Remember to check, if there are newer versions of [https://bitbucket.org/mpi4py/mpi4py/downloads mpi4py]. <br>
