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

Hi,
I would like to ask about running pvserver in parallel with MPI on multiple
hosts. Is that possible?
The following commands were tested successfully:
1)Running MPI on localhost:
mpiexec –n M localhost pvserver
2)Running MPI on remotehost:
mpiexec –host remotehost –n M pvserver
But I was not able to run: mpiexec –hosts 2 localhost 1 remotehost 1 pvserver
I run the following to test MPI on multiple hosts and it worked: mpiexec
–hosts 2 localhost 1 remotehost 1 hostname
Is there any pre-configuration that should be done to pvserver? I want the
clients to connect to the server (master server), and the jobs are distributed
across multiple nodes.
Regards,
Mariam
