Ok, back to basics - this is the simplest setup I can imagine.<br><br>I am trying to run pvserver on a single extra computer (so a total of mine + 1 = 2 machines) with the same architecture, same OS, same OpenMPI, same Paraview. I have been talking with the OpenMPI people and running "hello world" tests that are showing that everything is setup correctly and talking to each other with no problems. Both firewalls are off. Password-less ssh works both ways. pvserver is on both machine's PATH. I have compiled Paraview with PARAVIEW_USE_MPI set to ON in both cases. I have explicitly added the path to the openmpi libraries to LD_LIBRARY_PATH on both machines - that is, put the following in .bashrc on both machines:<br>
<br>export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib<br><br>I am starting the server with a paraview command like this:<br><br>
<meta name="qrichtext" content="1"><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><style type="text/css">
p, li { white-space: pre-wrap; }
