Charm++ parallel programming system

[Michael Robson <mprobson AT illinois.edu>]

Hello,

Instead of your current mpiexec strategy you might try

++mpiexec ++remote-shell "ibrun"

If that doesn't work you may need to add a -o 0 to tell it to offest 0. So the mpiexec portion would be:

++mpiexec ++remote-shell "ibrun -o 0"

Hope that helps and let us know if you run into any more trouble.

Sincerely,

Michael

Hello,

I have been trying to run my charm job on cluster that uses sbatch for submitting job scripts and ibrun for running them

My first trial with ibrun worked but yielded a job that ran independently on the processors (i.e. as if each job is run locally"

Some threads said that I need to write a script for mpiexec to deal with ibrun

So I wrote this script and named it mympiexec

#!/bin/csh
shift; shift; exec ibrun $*

and this was my job script

#!/bin/bash
#SBATCH -J FMM
#SBATCH -o %j32.o
#SBATCH -p normal
#SBATCH -n 16
#SBATCH -t 00:10:00
./charmrun +p16 ++mpiexec ++remote-shell ~/exafmm-charm/examples/

charmexec ./a.out

I get "couldn't locate mpiexec program" when that's run. I tried to put the shell in one of the PATHs and it was of no use.

here's my nodelist "~/.nodelist"

group main ++shell ssh

host localhost
