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



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!
