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
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
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".
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.
