Thanks for the input Mathieu.

> Why not 5.11.0 or 5.10.1

No good reason. I already had 5.10.0 on my local machine, and I was told I should use the same version on the server. I have now tried using 5.11.0, but encounter the same issue.

> make sure to use the right executable by using path

Yes, I am using specifying the path to the executables correctly. I was just being concise in my question!

> What is your system mpi ?

Our HPC has a bunch of different openmpi versions that I can load. I have tried with our system default (openmpi 4.0.0) and the newest version we have installed (openmpi 4.1.1), with and without the “–system-mpi” flag. Neither of these work. In both cases, I get an “Address already in use error” for every process, which has been documented elsewhere on this forum and is what led me to try downloading precompiled binaries (e.g. [ParaView Parallel pvserver (MPI) - Problems when running on a Cluster](https://discourse.paraview.org/t/paraview-parallel-pvserver-mpi-problems-when-running-on-a-cluster/10071)).

I get the same errors when I try to use some preinstalled versions of paraview on our cluster. I’m not sure if these were compiled on the system, but I think they might be because I was not able to use remote (mesa) rendering with them (whereas I am able to with the downloaded binaries).
