HP XC System 4.x Software - Manual (Page 59)

The ping_pong_ring application is submitted twice in a Makefile named mymake; the first
time as run1 and the second as run2:
$ cat mymake
PPR_ARGS=10000
NODES=2
TASKS=4
all: run1 run2
run1:
mpirun -srun -N ${NODES} -n ${TASKS} ./ping_pong_ring ${PPR_ARGS}
run2:
mpirun -srun -N ${NODES} -n ${TASKS} ./ping_pong_ring ${PPR_ARGS}
The following command line makes the program and executes it:
$ bsub -o %J.out -n2 -ext "SLURM[nodes=2]" make -j2 -f ./mymake
PPR_ARGS=1000000
Job <113> is submitted to default queue <normal>.
Use the squeue command to acquire information on the jobs:
$ squeue -s
STEPID NAME PARTITION USER TIME NODELIST
15.0 hptclsf@113 lsf lsfadmin 0:04 n14
15.1 ping_pong_ring lsf lsfadmin 0:04 n[14-15]
15.2 ping_pong_ring lsf lsfadmin 0:04 n[14-15]
The following command displays the final ten lines of the output file generated by the execution
of the application made from mymake:
$ tail 113.out

The following illustrates how an error in the Makefile is reported. This Makefile specifies a
nonexistent program:
$ cat mymake
PPR_ARGS=10000
NODES=2
TASKS=4
all: run1 run2 run3
run1:
mpirun -srun -N ${NODES} -n ${TASKS} ./ping_pong_ring ${PPR_ARGS}
run2:
mpirun -srun -N ${NODES} -n ${TASKS} ./ping_pong_ring ${PPR_ARGS}
run3:
mpirun -srun -N ${NODES} -n ${TASKS} ./ping_bogus ${PPR_ARGS}
