Most of your time is likely spent in I/O and data conversion rather than rendering. How are you getting your data into ParaView, i.e. what file format are you using? There is likely a better way that my address most of the performance issues you are having and remove the need for parallel rendering entirely. > Actually, my ultimate task is using ParaView Catalyst to implement in situ > visualization of a simulation that generates large datasets, but I'm still > in the very beginning stage of learning the Catalyst User's Guide. > If that's the case then you won't have the IO time with Catalyst that youre seeing with the ParaView application as the data will end up getting passed directly in memory.

Which driver version are you using (check with the nvidia-smi command)? If it's new enough, you may be able to use EGL which would be ideal.

If you'd still like to pursue it, please start a new thread by posting a message with the actual error you're getting. - Chuck
