NAME¶

makeflow_mpi_starter - mpi wrapper program for makeflow and workqueue

SYNOPSIS¶

makeflow_mpi_starter [options]

DESCRIPTION¶

makeflow_mpi_starter is an MPI wrapper program that will start Makeflow and WorkQueue on the nodes allocated to it. It is intended as a simple, easy way for users to take advantage of MPI-based system while using Makeflow and WorkQueue. To use it, the user simply needs to call it as one would a regular MPI program. For the program to work, cctools needs to be configured with --with-mpi-path.

OPTIONS¶

When makeflow_mpi_starter is ran without arguments, it will attempt to execute the workflow specified by the Makeflow dagfile.

EXIT STATUS¶

On success, returns zero. On failure, returns non-zero.

EXAMPLES¶

Run with debugging:

mpirun -np $NUM_PROC makeflow_mpi_starter -m "Makeflow.mf" -d mydebug

Run makeflow with custom port:

mpirun -np $NUM_PROC makeflow_mpi_starter -m "Makeflow.mf" -d mydebug -p 9001

Run makeflow with garbage collection

mpirun -np $NUM_PROC makeflow_mpi_starter -m "-gall Makeflow.mf" -d mydebug

Example SGE submission script

#!/bin/csh
#$ -pe mpi-* 120         
#$ -q debug              
#$ -N mpi_starter_example     
module load ompi
mpirun -np $NSLOTS makeflow_mpi_starter -m "Makeflow.mf" -d mydebug
