Maybe a MPI problem

ParaView Support
1

I want to make a cluster of paraview so I first put paraview on three virtual machines for test.
It works fine when I run command like mpirun -np 8 ./pvserver. But there will be an error when I run command like mpirun -n 3 -f /home/jerry/mpi_config_file ./pvserver.
The version of os I use on virtual machiens is ubuntu 18.04.
The version of paraview I use is ParaView-5.8.0-osmesa-MPI-Linux-Python2.7-64bit.tar.gz.
The version of mpi is 3.3a2.
And the error is as follows：

2020-07-15 02:05:40.154 (   0.681s) [        56175C00] vtkMPICommunicator.cxx:68    WARN| MPI had an error

You have to use the mpiexec/mpirun packaged in the ParaView bundle itself and not the one on your system. This will change in 5.9, but for 5.8 release, you have to use the one in the package.

Thank you!!!
I compiled the resources with mpi and successed runing pvsever in 3 machiens.
