<p class="MsoNormal">I currently have paraview 3.98.1 installed on a CentOS 6.2 cluster. The head node has X installed, but the compute nodes do not. I have built Paraview with the OSMesa, but cannot seem to get it to work on this server. I have a Debian
system with the same 3.98.1 installation built with OSMesa, and have no problems.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have tried running with mpi and also just a single instance, and am using pvserver, with a 3.98.1 client on my windows machine. I can make the connection on my client, and open a file. As soon as I attempt to view the file, in every
incantation I get similar error messages:<o:p></o:p></p>

<p class="MsoNormal">Based on information from the paraview wiki, I was under the impression that I should be able to use: pvserver –use-offscreen-rendering to force it to ignore any X connections, but so far, I have had no luck. The compute nodes do not have
X installed at all, and so I tried the reverse connection on the client, with the –use-offscreen-rendering and –ch –rc options, with the same results. Am I misunderstanding the use of OSMesa and –use-offscreen-rendering?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any assistance would be appreciated.<o:p></o:p></p>
