Hello. I am kind of new to Paraview. Hope this question isn't a stupid one. I can access to a shared-memory SGI Altix 4700 supercomputer. It has 6 GPUs and 64 cpus. I have successfully installed the latest version of paraview(3.4.0) on it. To my understanding, if I ssh to the supercomputer and type the following command, I can use one GPU to do the rendering job in the server end: DISPLAY=:0.0 mpirun -np 1 ./pvserver The problem comes if I want to use multiple GPUs to render a large data, say Image data from CT(about 1G) in real-time. How can I do it? Do I need to manually assgin other GPUs(:0.1, for instance) to cpus? On cluster, I know it's not a problem coz each cpu has its own gpu.
I also have tried to use multiple CPUs at the server end, for example: DISPLAY=:0.0 mpirun -np 4 ./pvserver However, the rendering results aren't correct in this case. No matter what data I opened, the rendering results were always some garbages(lots of dots with different color). The garbages appeared roughly where the data should be. I have no idea about the reason for this. My client end is a windows machine and the server is a linux supercomputer. Could that be a problem or I simply can't use one GPU for multiple CPUs? I have tried to get paraview work on the supercomputer for a very long time, and I got really frustrated. Any of your help would be highly appreciated! Aaron
