Hello,

Is it possible to activate X11-Forwaring on a job submitted via SLURM?

LSF had the Option in

#BSUB -XF

But I cannot find anything equivalent for SLURM in the documentation x11-forwarding is not possible atm. We are working on that feature. For some commercial applications like Wolfram Mathematica or Abaqus I would need the GUI interface to run my jobs. Why do you need the GUI within a batch job??? This should NEVER be needed. x11-forwarding is e.g. for debugging purposes, where you need to run the gui of a debugger, to debug code, which does not fit onto the frontends e.g. Many commercial applications, for which we provided LSF scripts, do have a GUI like abaqus, the ANSYS suite, Matlab ... The GUIs are not used within the batchjob. Generally speaking, a GUI within a batchjob does not make any sense, since you have to keep the connection alive from the frontend to your batchjob, or the GUI would vanish and the job die. We got x11-forwarding with LSF up and running only for the last few years. According to your question, we would not have been able to use any of these applications in batch before. And this is definitively not

Also I should add, that i would like to run these Applications in parallel with OpenMP, which was possible on LSF.

Is it not planned to supply this feature?

Ok, what does OpenMP mean? It does mean that a single process program uses several threads with shared memory. Coarsely spoken. Are you asking for "-a openmp"? This was only a hint for us regarding the accounting. If you need a job with x threads, you should use the following: --ntasks=1 --cpus-per-task=x Best Marcus
