[Paraview] visualizing xdmf/hdf5 files in parallel

[Inanc Senocak]

Hi Everybody,

We have a parallel structured Cartesian grid flow solver. We output our
solution file using xdmf/hdf5 format. File sizes are large (56 GB) so we
need to render the flow solution in parallel.

We are able to use VisIT to load and render the solution files (xdmf/hdf5)
efficiently. But we haven't had luck with Paraview. We use version 4.3.
Basically as we are loading the files, pvserver consumes all the memory per
node (64TB) and then it crashes. We are able to use pvserver to render (in
parallel) smaller simulation files (xdmf/hdf5) without any issues.

We have tried several options building pvserver but it did not make any
difference in rendering large files. Maybe there is a bug in the way our
simulation code writes xdmf/hdf5 files.

Does anyone have a large xdmf/hdf5 simulation file that we can download to
verify our paraview installation and its parallel rendering performance?

If you have any other tips/experiences regarding parallel rendering of
large xdmf/hdf5 files, please let me know.

Thank you!

Inanc
