Hi,<br>we have a Linux (Debian) cluster without gpu and we have a big problem using Paraview 3.6.1in client - server mode.<br>The server has been compiled with OSMesa library and following the instructions reported here (in particular the section "OSMesa support"):<br>
<br><a href="http://www.itk.org/Wiki/Setting_up_a_ParaView_Server">http://www.itk.org/Wiki/Setting_up_a_ParaView_Server</a><br><br>If we try to connect the client started with the command:<br><br>paraview<br><br>and the server, started with the command:<br>
<br>pvserver --use-offscreen-rendering<br><br>we must disable the checkbox "Remote rendering threshold" (but this causes bad performances) in the client settings (Edit -> Settings -> Render view -> Server), othervise Paraview crashes after loading a big input or performing some operation such us changing "outline" to "wireframe"...<br>
<br>The error always is (similar to):<br><br>ParaView3/Servers/Common/vtkServerConnection.cxx, line 67<br>vtkServerConnection (0x3182220): Server Connection Closed!<br><br>Executing with: 0<br>*** Process received signal ***<br>
Signal: Segmentation fault (11)<br>Signal code: (128)<br>Failing at address: (nil)<br>[ 0] /lib/libpthread.so.0 [0x7f4fc6536a80]<br>[ 1] /usr/lib/libGL.so.1(glBlendFuncSeparateEXT+0x16) [0x7f4fc7bc12e6]<br>*** End of error message ***<br>
Segmentation fault<br><br><br>This error also occurs if we start client and server logging directly (without any ssh connection) on the master node; on master node X is running and we can execute the test:<br><br>mpirun -np 4 /usr/X11R6/bin/glxgears<br>
<br>So, it doen't seem a problem regarding X connection and permission...<br><br>Moreover, executing the test:<br><br>/ParaView/ParaView-bin$ ctest -I ,,10<br><br>we obtain some segmentation fault, but the log file can't give any useful information.<br>

151/475 Testing TestParallelopipedWidget ***Exception: SegFault<br><br>..<br><br>On our local machine with gpu 100% test passed, and we haven't any problem to connect client and server on that machine.<br><br><br>
MPI version is: mpirun (Open MPI) 1.2.7rc2<br>OSMesa version is: 7.0.3-7<br><br><br>We searched on google, on Paraview wiki... without any succes: can you help us please?<br><br>If you need more information let us now<br>
<br>Thank you very much<br><br>Luis<br><br><br><br><br><br>
