Hi,

I want to run some ParaView and Catalyst2 tests and examples to validate a ParaView installation on a cluster\*. In particular I want to test rendering.

What would you all recommend?

Thanks in advance for any advice!

- a really really big and new cluster

Hi dave,

Starting in paraview 5.10, you can use the HPC benchmarks and validation suite.

`pvpython -m paraview.tests -o /tmp/resultsdir`

Unfortunately, pvpython fails with the same error message:

```auto
$ pvpython -m paraview.tests -o /tmp/resultsdir
Attempting to use an MPI routine before initializing MPICH
$ ll /tmp/resultsdir
