Relax For the model-free and relaxation dispersion analyses in relax, the optimisation can be speed up using Gary Thompson's multi-processor framework. This allows the calculations to be run some on a computer cluster. This uses OpenMPI via the [[mpi4py | optimizations]] with multi-processorsPython package. [http://www.nmr-relax.com/manual/Usage_multi_processor.html See the manual].<br>It needs requires the installation of '''openmpi-devel''' and the python package '''mpi4py'''Python package.<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>
The [https://code.google.com/p/mpi4py/ mpi4py] libraries can be installed on all Linux systems by typing [http://mpi4py.scipy.org/docs/usrman/install.html or check instructions here.]:
