Dear ParaView users, I recently set up a pvserver on our small cluster. I used the most recent stable ParaView release 5.1 and compiled from source.
The connection and rendering in client/server mode works fine in all representations except the "Volume" rendering. Here, depending on the model, either no model is shown at all (just the standard 3D render screen), or the previous representation with artifacts shows up. This seems to be a problem of the --use-offscreen-rendering flag that I use in the pvserver startup. I run the server on a node with 2 CPU (with 10 cores each) and 2 Nvidia Tesla K40c. I start the server with: xinit /usr/mpi/gcc/openmpi-1.6.5/bin/mpirun -np 4 pvserver -display :0.0 --use-offscreen-rendering : -np 4 pvserver -display :0.1 --use-offscreen-rendering In the client the threshold for remote rendering is set to 0. If I pass additionally the -tdx=1 and -tdy=1 flags the volume rendering is performed correctly, but the overall speed is decreased greatly. Thank you in advance for any help! Gunnar
