Interactive job
Interactive jobs should be used for debugging, graphics, or applications that cannot be run as batch jobs.

Allocate an interactive session and run the program. Sample session:

[user@biowulf]$ sinteractive --gres=gpu:k80:1 --mem=20g -c14
salloc.exe: Pending job allocation 46116226
salloc.exe: job 46116226 queued and waiting for resources
salloc.exe: job 46116226 has been allocated resources
salloc.exe: Granted job allocation 46116226

Batch job
Most jobs should be run as batch jobs.

Create a batch input file (e.g. gautomatch.sh). For example:

#!/bin/bash
set -e
module load gautomatch
gautomatch --apixM 1.34 --diameter 400 --T templates_lp40_3.2A.mrcs --apixT 3.2 --lave_D 100 --lave_min -0.8 --lsigma_cutoff 1.2  --cc_cutoff 0.25 test?.mrc

Submit this job using the Slurm sbatch command.

sbatch --partition=gpu --gres=gpu:k80:1 --cpus-per-task=14 --mem=20g gautomatch.sh
Swarm of Jobs
A swarm of jobs is an easy way to submit a set of independent commands requiring identical resources.

Create a swarmfile (e.g. gautomatch.swarm). For example:

gautomatch [...] test1_?.mrc
gautomatch [...] test2_?.mrc
gautomatch [...] test3_?.mrc

Submit this job using the swarm command.

swarm -f gautomatch.swarm -g 20 -t 14 --module gautomatch
where
-g # Number of Gigabytes of memory required for each process (1 line in the swarm command file)
-t # Number of threads/CPUs required for each process (1 line in the swarm command file).
--module gautomatch Loads the gautomatch module for each subjob in the swarm
