Re: [Condor-users] MPICH2 wrapper script (mpich2script) for parallel universe

["Nkwebi Peace Motlogelwa" <motlogelwan@xxxxxxxxx>]

Thanks Mark for the script...I just tried it and it works fine if the
parallel program is  executed on a single dedicated node.. The
script starts mpd on the master node (rank==0 or $_CONDOR_PROCNO ==0)
only, and if one has many dedicated execute nodes, the script does not
start mpd on the other nodes.. Will try to modify it to get it to start
mpd on all dedicated execute nodes..so far tried using mpdboot, but it
seems not as straight forward  to get the ring of mpd's working..

regards..

Hi Nkwebi,

I don't know if you still need this, but you can get my copy of
mp2script at:

http://www.escience.cam.ac.uk/~mcal00/condor/mp2script.asc

Copy and paste it, and rename it as mp2script. A couple of points you
should bear in mind: I had to put a .mpd.conf file in the home directory
of the user running condor (I use dedicated condor user accounts), but I
also had to set the env var MPD_CONF_FILE in the script, otherwise mpd
failed to find the file. I also load LD_LIBRARY_PATH with the compiler
libs I used to build mpich2 (I used ifort/icc 9.1). This script works
fine with the "cpi" example that gets built by mpich2 in
/path/to/mpich2/distro/examples.

Cheers,
Mark
