[Paraview] floating point exception error when doing slice filter (only happen when running pvserver remotely in parallel)

[Hong Yi]

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
