[Paraview] MPI on multiple nodes

[Patrick Begou]

I think the syntax for mpiexec is:

mpiexec -np 8 --host host_one,host_two pvserver

This would launch 4 occurences of pvserver on host_one and 4 on host_two.

1) first check mpi is running:

mpiexec -np 2 --host host_one,host_two hostname

This should print the name of the 2 hosts.

If it does not works check you can ssh from one host to the other without password.

2) You need the same paraview/pvserver install on the two hosts in the same 
location (not imposed but it is easier to launch)

3) May be use reverse connection from the parallel pvserver to the paraview 
client when you launch pvserver
