Hi. I’m looking to utilize mult-threading in a Trame/Paraview app utilizing MPI and possibly PvBatch. Although I have found some documentation for using MPI and PvBatch within ParaView I was wondering if there was some ParaView documentation specifically tailored to utilizing these feature in a Trame app that’s driven by Paraview/PvPython and see others were told on the Trame forum to come here for that type of guidance.

What might this basic setup look like in a for Trame? Are there any online examples I could look at?

MPI is multi-process, not multi-threading. Using trame with ParaView is already doing multi-threading with TBB on VTK filters.

For MPI and trame, you can read [that blog](https://www.kitware.com/exposing-web-application-with-paraview-5-13-is-getting-simpler/) which provide an example of mpi/pvbatch.

My bad. I misspoke there. Multi-_process_ is what I am trying to do _not_ multi-threading.  
I’m looking to use the different cores available on my processor and/or GPU to divide up tasks and process them simultaneously on the different cores.

I can check that blog you posted a link to, to read more about this. Thanks!
