serpent in SGE queuing system

Post by rullyh » Wed Jul 17, 2013 8:04 am

Dear fellas,

We are new to the SGE queuing System

I just wondering is there any body have experience combining open mp and mpi in SGE queuing system?

We have problem while submiting serpent2 jobs in SGE system. The SGE only recognize number of core which is defined by mpi, but not by open mp.

Thanks for suggestion

Hi rullyh,
I do not know your job scheduler, so my suggestion is probably useless.

Anyway, I had the same problem on blue gene/q: it did not recognize the omp parallelization in each node.
This is the final launching script which solved the problem.

Code: Select all


# @ job_type = bluegene
# @ bg_connectivity = MESH
# @ wall_clock_limit = 00:30:00
# @ notification = never
# @ bg_size = 64
# @ bg_rotate = FALSE
# @ job_name = flattop_1024_64_64_16o
# @ initialdir = .
# @ account_no = IscrC_MPMCF
# @ error = $(job_name)_$(jobid).err
# @ output = $(job_name)_$(jobid).out
# @ queue

export TASK_PER_NODE=1
export THREADS=16

echo "Job started at `date`"


runjob --np $TOTAL_MPI_PROCESSES --ranks-per-node $TASK_PER_NODE --env-all : $EXEC -omp $THREADS gpfs/scratch/userexternal/maufiero/input/sca_test/flattop_1024_64_64

echo "Job finished at `date`"

Dear all,
I m using SERPENT-v2 on a cluster where the ressources are handled by a SGE queuing system. I m running SERPENT-v2 within some scripts driving branch calculations, the end goal being the generation of few group cross sections.

Is there an easy way to obtain either from SERPENT-v2 or from the queuing system a signal telling that the SERPENT run in the queue is done?

Thanks a lot for your help,

Best regards,
