[mpich-discuss] problem with mpiexec while running parallel execution

[Jeff Hammond]

You're using mpibull2-1.3.9-18.s, which is not readily identified as a
version of MPICH2 (maybe the developers know it), although it seems to
be a derivative thereof.  Can you run
"/opt/mpi/mpibull2-1.3.9-18.s/bin/mpiexec -info" to generate detailed
version information on your MPICH2 installation?

Regardless of the version of MPICH2 you are using, your problem has to
do with MPD, but MPD is no longer supported.  You can refer to
http://wiki.mcs.anl.gov/mpich2/index.php/Frequently_Asked_Questions#Q:_I_don.27t_like_.3CWHATEVER.3E_about_mpd.2C_or_I.27m_having_a_problem_with_mpdboot.2C_can_you_fix_it.3F
for more information.

Hydra is the replacement for MPD and it is an excellent process
manager.  The system administrators at your site should install a more
recent version of MPICH2 that will have Hydra as the default process
manager.  If your machine has Infiniband, recent versions of MVAPICH2
(which is derived from MPICH2) will also have Hydra support.

Best,

Jeff
