[mpich-discuss] mpdlib.py warning

[James Dinan]

Hi Rohit,

Those are warnings from the Python interpreter about modules used by MPD 
that have changed names.  You can safely ignore them for right now, but 
eventually those deprecation warnings will become errors.

Over the past several years, we have written a new process manager 
called hydra that replaces MPD.  Hydra is functionally equivalent and 
significantly better than MPD, so we have discontinued support for MPD. 
  The version of MPICH2 that you have is quite old; if you update to a 
newer version, it will include hydra as the "mpiexec".

Best,
  ~Jim.
