Andy I appear to be suffering from a confusion of what the catalyst framework does - or how it is used ...
I had imagined that I’d run a simulation on N ranks, have catalyst bound to them and be able to do vis on those N ranks. But in fact, when I connect to a live simulation, I have to “extract” results from them and then render them back on the client. Is this the case or did I miss something? The parallel image generation appears to work as advertised, but the images go off to disk and not to the renderwindow. Is there a way on configuring it so that I can see the actual rendering taking place in the renderview? I wanted to display the contents of a custom render plugin using cuda based rendering on many GPUs and be able to interact with it, but I am obviously missing something in my setup. thanks JB From: Andy Bauer [mailto:[email protected]] Sent: 26 August 2014 15:34 To: Biddiscombe, John A. Cc: [email protected] Subject: Re: [Paraview] Catalyst question Hi John, This live capability is now available and recently has been cleaned up quite a bit. There are still a couple more small changes that are waiting a code review process before they go into the master branch. The user's guide needs an update for a bunch of new information (live, catalyst editions, zero-copy arrays) that's important for Catalyst. We're also doing some preliminary testing with a newly developed ADIOS writer for better IO performance as well. Getting back to the live viz stuff, when you create a Catalyst Python script and export it using the wizard you'll have the option to enable live viz (it's the same wizard page as the screenshot output specification). Then, while your simulation is running use the Catalyst->Connect option to connect. There are two tests (pv.CatalystLiveSetBreakpoint and pvcs.CatalystLiveSetBreakpoint) that demonstrate the newly implemented live functionality which now includes the option to set a breakpoint in the simulation. If you get a chance to try it out, let me know what you think.

I had thought this capability was now possible, but I have not been following development closely and it looks like I was mistaken. Is it possible to visualize the simulation live - rather than just generate images (which works fine). (I had a quick skim through the user manual, but didn’t see this feature mentioned).
