[mpich-discuss] mpdlib.py warning

[Dave Goodell]

Use an older python or a newer version of mpich2.  The latest versions of MPICH2 use the newer hydra process manager instead, deprecating mpd.  There exists some version of MPICH2 (>1.0.6) with an mpd that suppresses that warning, but I would recommend using hydra instead anyway.
