Hi Andy,
Welcome back from hols!
This actually missed the question.
I assume that we get whatever pvserver up and running in parallel
(generally have indeed used a pvserver build with mesa and llvmpipe
rendering), how do we attach to it from catalyst?
Using a GUI "connect" button seems pointless/self-defeating, but how can
I convey to catalyst that I'd like to connect to a particular server?
Cheers,
/mark

Hi Mark,
If you want to create images from Catalyst runs you'll probably want to
build the ParaView that you're linking to with either OSMesa or EGL (and
Qt disabled). This gets around needing the X context for rendering since
I believe running with offscreen enabled is not sufficient. EGL comes
with most of the NVIDIA drivers -- see
https://blog.kitware.com/off-screen-rendering-through-the-native-platform-interface-egl/
for how to build PV with it. If you want to go the OSMesa route I'd
recommend using the ParaView superbuild
(https://gitlab.kitware.com/paraview/paraview-superbuild) to build it
for you.
Does this answer your question? I just got back from vacation and am
trying to catch up on more things than my brain can currently handle so
let me know if you have more questions.
Best,
Andy

For the mailing list, since this must probably be a FAQ (even if I seem
to find the answer in the usual places).
I would like to have paraview rendering in parallel for a simulation
with catalyst. For simplicity, I'm fiddling about on a local
workstation, but would like to generalize later. it should work without
live visualization enabled, or requiring a GUI to connect.
I'd presume using something like the following
mpirun -np 12 pvserver --server-port=123456 --force-offscreen-rendering
would be setup a parallel rendering session as usual. However, after
scouring docs there doesn't seem to be an obvious way to connect this
within catalyst (without a GUI).
The only access point that I seem to find is to define an MPI
communicator for initializing catalyst after some how (some hand-waving
here) querying a pvserver connection for its host topology and defining
an appropriate communicator.
Cheers,
