I compiled ParaView v5.10.1 myself with osmesa and system OpenMPI on AlmaLinux 8.5.
pvbatch does work and pvserver waits for clients. However, when a client connects, the client crashes and closes itself and the server says the following:
Alternatively I tried using the provided binaries with the --system-mpi option. This does lead to another problem. Does the --system-mpi option work with OpenMPI v4.1.2?
My HPC system has IntelMPI (no header files so compilation no possible), OpenMPI (hpcx version that is optimized for the used infiniband network) and MVAPICH2 which I’ve never used.
Using MVAPICH2 with --system-mpi does work. However I would prefer to run ParaView with OpenMPI because on the same system other tools are already based on OpenMPI and changing the module in between an automated workflow is currently not implemented.
Any ideas why my self-compiled code has connection issues?
We recently fixed a problem that may be related (i.e. vtkSocketCommunicator (0x1932c20): Tag mismatch ) . So maybe you will be more lucky with the master branch ?
