Re: r20981 - in /branches/relax_disp/specific_analyses/relax_disp: api.py optimisation.py -- September 11, 2013 - 18:40

Hi Edward.

I just tried it out, and I got it to work. :-)

I added these sections to the wiki:
http://wiki.nmr-relax.com/Installation_linux#mpi4py
http://wiki.nmr-relax.com/Installation_linux#Script_for_running_the_disp_branch_of_relax_with_maximum_number_of_processors_available

Section on mpi4py
http://wiki.nmr-relax.com/Mpi4py

Should some speed test be provided here?

Looking forward to try it !
