Hi,

I am trying to run ParaView in parallel in a cluster’s visualization node with 36 cores:

```auto
[alvesrig@irene7100 fine-hex]$ whereis mpiexec
mpiexec: /ccc/scratch/cont003/gen7178/alvesrig/ParaView-5.10.1-MPI-Linux-Python3.9-x86_64/bin/mpiexec
[alvesrig@irene7100 fine-hex]$ whereis pvserver
pvserver: /ccc/scratch/cont003/gen7178/alvesrig/ParaView-5.10.1-MPI-Linux-Python3.9-x86_64/bin/pvserver

```

But I am getting the following error:

```auto
[alvesrig@irene7100 fine-hex]$ mpiexec pvserver -n 36
'.pvx' file is deprecated please use '--pvx' instead
( 0.175s) [pvserver]vtkDisplayConfiguration:163 ERR| vtkDisplayConfiguration (0xdd13c0): Failed to parse XML: 36
File was not found
Could not convert: '.pvx' file = 36

```

Could you help me figure out what is going on?

Thanks a lot,

---

Sorry, it was my mistake. Just use:

`mpiexec -n 36 pvserver`

Notice the position of `-n 36`.
