Additional Information

Sharing your display with co-workers

When setting the VNC password you will be asked if the password should be view-only and if you answer yes ("y"), you will be asked for another VNC password. You can give this password to co-workers, so that they can log-on to your VNC session, e.g. to discuss new results over the phone. Your co-workers will see what you see, but their inputs will be ignored.

Getting information about the system

You can find out about the general availability of the GPUs in the gvs cluster by using the command

     sinfo

which tells you the availabilty of render nodes

PARTITION    AVAIL  TIMELIMIT NODES STATE  NODELIST
gvs_inter*   up      12:00:00     2 alloc  gvs[1-4]

This listing tells you that gvs1-gvs4 are available.

In order to check the use of the GPUs on the several servers you can issue the command

    squeue

which gives you a listing of the running and queued requests for GPUs.

JOBID PARTITION   NAME      USER        STATE       TIME TIMELIMIT  NODES NODELIST(REASON)
249   gvs_inter   vglslurm  a2815ah   PENDING       0:00  12:00:00     1  (Resources)
228   gvs_inter   vglslurm  a2815ai   RUNNING    9:03:01  12:00:00     1  gvs3
245   gvs_inter   vglslurm  a2815ah   RUNNING      30:37  12:00:00     1  gvs3
246   gvs_inter   vglslurm  a2815ah   RUNNING       0:50  12:00:00     1  gvs4
248   gvs_inter   vglslurm  a2815ah   RUNNING       0:32  12:00:00     1  gvs4

The above listing means that all 4 GPUs of gvs3 and gvs4 together are in use and the second user has already used up 9:03 hours and will be terminated when the 12 hours are used up. After that time the pending job from the first user will obtain the free GPU. It is no longer possible to make an advance reservation of a GPU in the future, because the GPUs are served: "come first serve first".

Available directories

Additionally there exists a scratch file system for transfer of large data from SuperMUC to the new RVS Cluster. The scratch file system is available on all SuperMUC login nodes and on the RVS nodes under $SCRATCH_RVS.

Running own applications

Using this VNC-desktop you can now run OpenGL Software packages either pre-installed in the LRZ module system or user installed in your home directory by using the prefix command rvglrun.

    rvglrun
