module load presto

cd /data/$USER/dir
presto command

Then submit the file on biowulf

biowulf> $ sbatch script.sh

Swarm of Jobs on Biowulf

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

# this file is called script.swarm
cd dir1;presto command 1; presto command 2
cd dir2;presto command 1; presto command 2
cd dir3;presto command 1; presto command 2

Submit this job using the swarm command.

$ swarm -f script.swarm --module presto

Interactive job on Biowulf

Allocate an interactive session. Sample session:

[biowulf ~]$ sinteractive --mem=5g
salloc.exe: Pending job allocation 15194042
salloc.exe: job 15194042 queued and waiting for resources
salloc.exe: job 15194042 has been allocated resources
salloc.exe: Granted job allocation 15194042
