Hi Jeff,<br><br>Which version of paraview source code are you compiling, and which version of osmesa are you using?<br><br>Pat<br><br><div class="gmail_quote">On Wed, Nov 24, 2010 at 6:16 PM, Jeff Mauldin <span dir="ltr"><<a href="mailto:jamauld@sandia.gov">jamauld@sandia.gov</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">I am trying to run a paraview server (pvserver) on a multinode machine using osmesa to do offscreen rendering (and then viewed from a client on another machine).<br>
<br>
I have been successful in compiling pvserver with osmesa. However, when I try to use pvserver, it hangs. Specifically, I start a paraview client on machine A (bentley) and ask for a reverse-connection connection to a pvserver which I will start manually on machine B. I go to machine B and start pvserver (in reverse connect, with machine A specified as the client host).<br>
<br>
The connection is successful insofar as the output on the terminal I started pvserver on on machine B says<br>
<br>
Connected to client.<br>
<br>
However, no rendering occurs on the paraview client on Machine A.<br>
<br>
quite a bit of digging later (including putting some printf calls into pvserver on machine B), I've figured out where the hang is:<br>
<br>
In<br>
<br>
vtkPVSynchronizedRenderWindows::SynchronizeBounds<br>
we are in case RENDER_SERVER and we freeze during either the<br>
c_rs_controller->Send<br>
or<br>
c_rs_controller->Receive<br>
call.<br>
<br>
A bit of the call stack is:<br>
<br>
vtkPVSynchronizedRenderWindows::SynchronizeBounds<br>
vtkPVRenderView::GatherBoundsInformation<br>
vtkPVRenderView::Render<br>
<br>
I belive this is the first render attempt made by pvserver.<br>
<br>
I had compiled pvserver without MPI and am currently trying to recompile it with MPI.<br>
