Thanks for your reply. The correct syntax to run on multiple hosts is: mpiexec –hosts N localhost M remotehost 1 appName
I tested with hostname and it worked; it printed the expected output. However, by executing the same command with pvserver, it does not work. I ensured the location of paraview/pvserver is the same across both hosts. And I am providing the full path of pvserver. I would like to make sure that I understood the concept correctly: >From host1, if I executed parallel pvservers with MPI (host1, host2, hostN), >the clients should connect to host1. Can you please confirm?

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 Patrick Mariam wrote: 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.
