[Paraview] How to run a simulation with Catalyst and display the result using tiled display?

[张驭洲]

Hello,

I want to visualize a simulation program in situ and display it using a tiled screen. I can run the simulation with Catalyst and MPI, and I can also configure ParaView for a 3x2 tiled screen. However, if I run paraview with tiled display, the control of the servers' window will be taken by paraview so I can't start the simulation program. I tried to start the simulation through ssh, but after connecting to the simulation using Catalyst, the simulation program crashed with these errors:

ERROR: In /root/Desktop/ParaView-v5.2.0/VTK/Common/System/vtkSocket.cxx, line 481
vtkClientSocket (0x1f0bbb0): Socket error in call to connect. Connection refused.

ERROR: In /root/Desktop/ParaView-v5.2.0/VTK/Common/System/vtkClientSocket.cxx, line 53
vtkClientSocket (0x1f0bbb0): Failed to connect to server localhost:22224

ERROR: In /root/Desktop/ParaView-v5.2.0/VTK/Parallel/Core/vtkSocketCommunicator.cxx, line 714
vtkSocketCommunicator (0x3798ec0): Can not connect to localhost on port 22224

APPLICATION TERMINATED WITH THE EXIT STRING: Aborted (signal 6)

Actually the Catalyst connecting port should be 22222 and when I click "Catalyst---->connect" in  the GUI, it is indeed 22222. I don't know why the port in the error message is 22224. I noticed that if I let Catalyst to output images, there will be windows of the same number of mpi simulation processes on the server, but the windows is of the same size of the view in the GUI on the client, which sames not for tiled display.

So, is it possible to display the result of in situ visualization with tiled display?

Thanks a lot!
