Re: [Pympi-users] pyMPI with mpich2-1.0.4p1 ???

[Pat M. <pat...@gm...>]

Hola Jairo...

I haven't build pyMPI with MPICH2 though I had expected that it would
work.    I have a parallel Fedora machine at home so I can try this over
the weekend and let you know if I can repeat your results.

Cheers,
Pat
