I have set up a two node cluster, each compute node has 4 cores

To fully utilise all the cores in both nodes, is this the correct to launch pvserver ?

```auto
/shared/ParaView-5.10.1-osmesa-MPI-Linux-Python3.9-x86_64/bin/mpiexec -hosts compute0,compute1 -np 8 /shared/ParaView-5.10.1-osmesa-MPI-Linux-Python3.9-x86_64/bin/pvserver

```

Cheers
