Jobscript-examples

These examples are very minimal and intended to give a rough overview of the functionality of jobscripts. They contain comments starting with "###" that explain the code. Follow one of these links to view the examples, depending on the scheduler that manages your facility's batch system: LSF, SLURM, Torque. If you're not sure, go to this overview to figure out, which scheduler is used in your case.

Serial Job

This job will run a given executable, in this case "myapp.exe".

#!/usr/bin/env zsh

### Job name
#BSUB -J MYJOB

### File where the output should be written
#BSUB -o MYJOB_OUTPUT.txt

### Time your job needs to execute, e. g. 1 h 20 min
#BSUB -W 1:20

### Memory your job needs, e. g. 1000 MB 
#BSUB -M 1000

### Stack limit per process, e. g. 20 MB
#BSUB -S 20

### The last part consists of regular shell commands:
### Change to working directory
cd /home/user/mywork

### Execute your application
myapp.exe

OpenMP Job

This job will start the parallel program "myapp.exe" with 24 threads.

#!/usr/bin/env zsh

### Job name

### Time your job needs to execute, e. g. 15 min
#BSUB -W 0:15
