[Paraview] [Non-DoD Source] Building on Cray systems

[Andy Bauer]

Hi Rick,

Did you build ParaView with PARAVIEW_INSTALL_DEVELOPMENT_FILES enabled? Tim
will need that for using Catalyst if he's going to be using your builds but
not if he's going to do his own.

Tim, some questions on what you need:

   - Do you have a specific compiler and version you want/need to use? Same
   thing for MPI implementation.
   - Do you have a specific version of ParaView that you want to use?

I would recommend using the superbuild tools, to build statically with
Python and Mesa. The other libraries can be built with the superbuild
(definitely use system MPI though) for convenience even though for
Catalyst  you probably won't need many of them. The FREEZE_PYTHON option is
to statically linking the other Python modules into the executable. This is
definitely useful for when running with a high number of MPI ranks since
when loading a module (e.g. paraview.simple) in parallel it can really kill
the file system if thousands of processes are simultaneously trying to load
a bunch of Python modules. Note though that this isn't needed for a
Catalyst Python script since that is done specially where process 0 reads
the file and broadcasts it to all of the other processes.

Cheers,

Andy
