For computing jobs with high I/O performance demands, users can leverage the internal SSDs of the nodes. The BeeOND (BeeGFS on Demand) temporary file system enables users to utilize the SSD storage across all requested nodes as a single, parallel file system within a single namespace.

Key Considerations when using BeeOND:

• The amount of allocated storage depends on the type and number of requested nodes.
• Computing jobs that use BeeOND will become exclusive.
• Within the job, the file system path for BeeOND is accessible via the environment variable $BEEOND.
• The storage space on the filesystem is strictly temporary! All files will be automatically deleted after the computing jobs concludes.

This example job script shows how to use BeeOND:

#!/usr/bin/zsh

### Request BeeOND
#SBATCH --beeond
### Specify other Slurm commands

### Copy Files to Beeond
cp -r $WORK/yourfiles $BEEOND

### Navigate to Beeond
cd $BEEOND/yourfiles

### Perform your job
echo "hello world" > result

### Afterwards copy results back to your partition
cp -r $BEEOND/yourfiles/result $WORK/yourfiles/
