I managed to compile it! Thank you. I now need to figure out how to use it...it does not seem as simple as telling the paraview how many cores to use as all I get is visual artifacts instead of real output (I see a field with spots, instead of the expected slice visualization that I get when I only run paraview on a single core). Doing mpirun on pvserver also does not seem to do much (spots, and same speed) while attempting to use pvrenderserver does not work - not without delving into exactly how to make it work - the client connects, but no rendering happens...
I will look at the documentation and the web first before asking for help... On 18 June 2014 20:46, Victor <[email protected]> wrote: > Thank you for the advice.
