Just some follow-up information I hope to shed some light on this problem. I
used pdb to debug pvserver running with mpirun on the server and found this
floating point exception error happens on the line below:
Program received signal SIGFPE, Arithmetic exception.
0x00002ad33e95021b in vtkViewport::DisplayToView (this=0x43a2670)
at
/home/hyi2/Download/ParaView-3.14.1-Source/VTK/Filtering/vtkViewport.cxx:204
204 (sizex*(this->Viewport[2]-this->Viewport[0])) - 1.0;
which puzzles me since I cannot imagine why this could cause floating point
exception (I cannot see possibility of "divide by zero" or other possible
arithmetic exception). I did try to check or uncheck "Remote Render Threshold"
checkbox both ways which results in the same failure in the same statement as
noted above. Also, isocontouring filter runs fine with correct visual output,
but slicing and clipping filters result in same errors as noted above.
Hope this additional debug info could shed some light and trigger some idea on
what could be the problem. Perhaps there is a possibility it is NVidia driver
related? But in my configuration, HPC server uses MESA software rendering and
my client NVidia driver is up to date with Geforce GTX580 graphics card.
Thanks for any ideas on what could cause this problem!

Subject: [Paraview] floating point exception error when doing slice filter
(only happen when running pvserver remotely in parallel)
I built ParaView server with MPI on a HPC cluster with OSMesa support since the
cluster does not have graphics hardware. The MPI compiler used to build
ParaView is mpich2/gnu412x64/1.4-shared. Paraview server built successfully on
the cluster without any error. I can successfully connect to the pvserver
running on multiple nodes remotely via Paraview client running on my local
desktop, load data in, and do gradient and vorticity computation, and look at
isosurfaces without problems. However, when I do slice filter to look at one
slice, as soon as I click on slice filter, pvserver aborts with floating point
exception error. It is not the data problem because I can do slice filter
without problem for the same data if I run builtin Paraview server/client
locally, so the problem only occurs when the local client connects to pvserver
running remotely on multiple nodes (or on one node) via mpirun. So far, the
slice filter is the only filter I have run into with this floating point
exception error raised by the remote pvserver. The other filters such as
gradient of unstructured data, calculator of vorticity, isocontour all run
successfully with correct results produced. Any idea on what could cause this
problem is very much appreciated!
Thanks,
Hong
