<div dir="ltr"><div><div>Hi John,<br><br></div>You are correct that the rendering that's done by Catalyst to create images is not directly available to the client. I hope to fix this in the not too distant future. The idea being that you select which Catalyst view you want to interact with and then it switches the view to that such that you can update view options like camera angles, lookup tables, etc. as well as output frequency and filename for that view when from Catalyst.<br><br></div>As for creating a live connection to a Catalyst enabled simulation, maybe the thing you want is to use a live connection with pausing the simulation to get to data at a specific point in the simulation. If this data is too much to download to the client you can create a separate pvserver to connect to Catalyst and then connect your client to that pvserver. I haven't tried this but Utkarsh said that it was designed to work this way. <br><br>Does this sound like a reasonable way of doing what you want? Now that the live functionality also has the ability to pause a simulation, it's feasible that we could go the libsim route and have Catalyst act as server for everything instead of downloading it to the client or separate server. We just haven't had a lot of impetus for providing that use case yet so we've focused on other stuff.<br><br>Regards,<br>Andy<br><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Oct 16, 2014 at 8:58 AM, Biddiscombe, John A. <span dir="ltr"><<a href="mailto:biddisco@cscs.ch" target="_blank">biddisco@cscs.ch</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<br>
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.
<u></u><u></u></div></div><p></p>
</div><div><div class="h5">
<p class="MsoNormal" style="margin-bottom:12.0pt">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.<u></u><u></u></p>
