[PerfSuite-users] Re: Psrun with argonne mpich

[Rick K. <rk...@nc...>]

Vangal,

Yes, it should be possible to use psrun with MPICH.  Some of the things 
that may be required are to use the full path name to the psrun executable 
and also to make sure that the environment settings such as LD_LIBRARY_PATH
are set properly, especially if you're using a variant of MPICH
like ch_p4.  One way to set that up is to add it to your dot-files
like .cshrc or .profile, that way you'll be sure that the ssh to
the remote nodes picks up the right values.

Just to be clear, the command line might be something like:

mpirun -np 8 -machinefile machines /usr/local/bin/psrun mpi_program

If these suggestions don't work, then please send any error output
you can get from the run and hopefully can figure it out...
