This is pretty awesome. I am assuming that this has something to do with things not fitting on the GPU memory or exceeding some texture memory limitation. Can you provide some more details?
* Which version of ParaView are you using? * It sounds like you have multiple GPUs and multiple nodes. What is the setup? Are you running in parallel with MPI? * If you are running parallel with MPI and you have multiple GPUs per node, did you setup the DISPLAYs to leverage the GPUs?
