[mpich-discuss] failed processes

[Jayesh Krishna]

Hi,
 If you install MPICH2 on Windows using the windows installers (*.msi) you currently do not have support for disabling auto cleanup of MPI processes (SMPD is the only process manager that is included when MPICH2 is installed using the windows installers. Since SMPD does not support disabling auto cleanup of MPI processes you do not get the feature with MPICH2 on windows).
 If you install MPICH2 on Windows using Cygwin (http://www.cygwin.com/), you should be able to install MPICH2 like in a Unix system (You configure/make/make install to install MPICH2 - See http://www.mcs.anl.gov/research/projects/mpich2/documentation/files/mpich2-1.3-README.txt for details - from a Cygwin prompt). When installing MPICH2 using "configure/make/make install" steps on Cygwin the default process manager available is Hydra. Hydra supports disabling auto cleanup of MPI processes (As Darius suggested pass "-disable-auto-cleanup" as an argument to mpiexec ; mpiexec -n 2 -disable-auto-cleanup ./my_mpi_pgm).
 So, if you need to disable auto cleanup of MPI processes you need to install MPICH2 on Cygwin. Let us know if you need further help.

Regards,
Jayesh

So..as a conclusion, how can I pass -disable-auto-cleanup parameter to
mpiexec in windows platform using wmpiexec gui wrapper? I think it has not
been explained yet. Sorry for these simple silly questions.
