[Paraview] Parallel rendering in the cave

[Max Reimann]

I am trying to get parallel rendering to work in ParaView 5.1 in a multi-display environment (cave) and keep getting this error when connecting from a client to a single or multiple render servers.


""

ERROR: In /da/sw/paraview/ParaView-5.1.0-source/ParaViewCore/ClientServerCore/Rendering/vtkPVRenderView.cxx, line 1404
vtkPVRenderView (0x1497060): In Cave mode and Display cannot be opened on server-side! Ensure the environment is set correctly in the pvx file.

I have followed the steps on the wiki and now trying to get a single rendering display to work. My cave.pvx looks like this:


<?xml version="1.0" ?>
<pvx>
 <Process Type="client" />
  <Process Type="server">
  <Machine Name="dev1"
           Environment="DISPLAY=:0"
           Geometry="1920x1080+5760+0"
           LowerLeft=" 0 -0.5 -2"
           LowerRight="1.78 -0.5 -2"
           UpperRight="1.78  0.5 -2" />
  <Machine Name="dev1"
           Environment="DISPLAY=:0"
           Geometry="1920x1080+3840+0"
           LowerLeft=" -1.78 -0.5 -2"
           LowerRight="    0 -0.5 -2"
           UpperRight="    0  0.5 -2" />
 </Process>
</pvx>



And I start it with


mpirun -d   --report-bindings -H da-dev1 -np 2 /paraview/install-5.1/bin/pvserver -sp=2052 /paraview/tvs.pvx



I have disabled all firewalls and set xhost to disable access control, but to no avail.
Starting paraview with x-forwarding works, however this can't work on multiple rendering displays, I assume.

Specs are:

- linux gentoo x64

- paraview 5.1 with vrplugin, openmpi, vrpn
