[Paraview] Catalyst osMesa rendering time

Tue Sep 13 11:35:12 EDT 2016

Hi Andy,

It appears that the changes to the cmake configuration file haven’t been able to prevent the opening of a window onscreen, nor has changing the Mesa version to 12.0.2 done anything to change the runtime behavior. I want to back up and make sure I’m not doing something wrong when running Catalyst. Do I need to change any steps in my process of running a code that has been instrumented to use Catalyst? i.e. Do I need to add any additional arguments or change the catalyst python scripts in any way to tell it  to use offscreen rendering?

Thank you,

Chris

Hey Andy,

I should have also noted that I was using Mesa 9.2.2 for my build.  I found a blog post by Utkarsh where he talks about building ParaView with osMesa enabled (https://blog.kitware.com/messing-with-mesa-for-paraview-5-0vtk-7-0/ ) . It looks like he was using a newer version of Mesa, so I downloaded 12.0.2, and I will try again using that.

I think the missing item is that you need to set VTK_USE_OFFSCREEN to ON.

Thanks Andy,

The file is quite large, so I have attached it.

I tried to follow the process that is explained at(http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D) so I made a shell script that contains all of the arguments passed to cmake. It is shown below.

#!/bin/bash

Hi Chris,

It sounds like you didn't properly build ParaView with offscreen rendering. Can  you share your CMakeCache.txt from your build? I'm guessing VTK_USE_X, VTK_USE_OFFSCREEN or some other thing didn't get set properly.

Hi all,

I have compiled a version of ParaView with osMesa enabled. The version is 5.1.2 for ParaView. I’m running the CxxFullExample Catalyst example that is located in ParaView/Examples/Catalyst.

Operating system info

lsb_release –a: 
LSB Version:         n/a

Distributor ID:     openSUSE project

Description:         openSUSE 13.2 (Harlequin) (x86_64)

Release:                13.2

Codename:           Harlequin

I have added 1 additional script to the Catalyst example by using the “CoProcessing” button in ParaView to generate a Catalyst script that just exports a .png of an isometric view of the geometry. When I run the example, the operating system seems to freeze up completely in my login session i.e. windows can not be clicked, nothing at all can be done with the exception of moving the mouse around on the screen. It stays frozen like this for about 2 minutes before a window pops up that says “Paraview(batch)”. In the window is the isometric view and the window updates to show the geometry at every timestep that the example outputs an image at. The Catalyst script does seem to execute fine and outputs image files for each frame that I requested, but it is soooo slow for some reason.

Is this the expected behavior of running Catalyst with an osMesa build? I thought that ‘os’ stood for ‘off-screen’, which I interpreted as there being no screen display component to the rendering. Have I done something wrong with compiling ParaView with osMesa? Is Catalyst supposed to completely lock up the session until a window pops up?  

I would love to hear from other users of Catalyst to hear about the experiences of running Catalyst.

Thank you,

Chris Neal
