Re: [HTCondor-users] Cannot use multiple arguments to run MPI application in "parallel" universe

[Jason Patton <jpatton@xxxxxxxxxxx>]

Here's my submit file:

---

universe = parallel

executable = openmpiscript

arguments = mpi_wrapper.sh

transfer_input_files = a.out, mpi_wrapper.sh

getenv = true

should_transfer_files = yes

when_to_transfer_output = on_exit_or_evict

+ParallelShutdownPolicy = "WAIT_FOR_ALL"

output = out.$(NODE)

error  = err.$(NODE)

log    = log

request_cpus = 1

machine_count = 4

queue

---

Here's mpi_wrapper.sh:

---

#!/bin/sh

if [ "$_CONDOR_PROCNO" -lt 2 ]; then

    exec ./a.out '_CONDOR_PROCNO='$_CONDOR_PROCNO args1

else

    exec ./a.out '_CONDOR_PROCNO='$_CONDOR_PROCNO args2

fi

---

I'm using $_CONDOR_PROCNO to figure out which node of my MPI job is running and passing arguments to my MPI application (a.out) based on its value.

Hi Jason,

Sorry for late reply. I have tried your method, but it didn't work. Could you please send me your submit file and other stuff so that I can try it on my machines.

Thanks for your help!
