Using ''/scratch2''

Currently the latest nodes do NOT have an access to /scratch. They have an access only to shared /scratch2.

If you use scratch space only for storing temporary data, and do not need to access data stored previously, you can request /scratch or /scratch2:

#BSUB -R "scratch||scratch2"

For that case /scratch2 is linked to /scratch on the latest nodes. You can just use /scratch/${USERID} for the temporary data (don't forget to create it on /scratch2). On the latest nodes data will then be stored in /scratch2 via the mentioned symlink.

Miscallaneous LSF Commands

While bsub is arguably the most important LSF command, you may also find the following commands useful:

Lists current jobs. Useful options are: -p, -l, -a, , <jobid>, -u all, -q <queue>, -m <host>.

Lists older jobs. Useful options are: -l, -n, <jobid>.

Status of cluster nodes. Useful options are: -l, <hostname>.

Status of batch queues. Useful options are: -l, <queue>.

Why do I have to wait? bhpart shows current user priorities. Useful options are: -r, <host partition>.

The Final Command. It has two use modes:

  1. bkill <jobid>: This kills a job with a specific jobid.
  2. bkill <selection options> 0: This kills all jobs fitting the selection options. Useful selection options are: -q <queue>, -m <host>.

Have a look at the respective man pages of these commands to learn more about them!

Getting Help

The following sections show you where you can get status Information and where you can get support in case of problems.

Information sources

Using the GWDG Support Ticket System

Write an email to In the body:

  • State that your question is related to the batch system.
  • State your user id ($USER).
  • If you have a problem with your jobs please always send the complete standard output and error!
  • If you have a lot of failed jobs send at least two outputs. You can also list the jobids of all failed jobs to help us even more with understanding your problem.
  • If you don’t mind us looking at your files, please state this in your request. You can limit your permission to specific directories or files.
