Description

Since the CarpetHDF5 reader (https://svn.cactuscode.org/VizTools/CarpetHDF5) was included in VisIt's main source code repo, we have not attempted to update that copy to the most current version. The coding style in that branch matches the official code but the patches do not apply on top of the official code due to ordering issues as well as some minor new changes to code formatting in the current (2.8.0) VisIt codebase.

Since then, I have collected a number of bugfixes/improvements that are collected in various branches at https://bitbucket.org/rhaas80/carpethdf5 . It would be good to eventually try and get the for_VisIt branch (https://bitbucket.org/rhaas80/carpethdf5/branch/for_VisIt) included in the main source code repo again.

It contains some bug-fixes wrt how file metadata is cached, as well as number of fixes to reduce memory footprint, number of open files (required to work on large datasets on machines that limit the total number of open files), some improvements to error reporting and robustness when dealing with partially corrupted filesets as well as changes that allow a user to combine multiple HDF5 files into a single "virtual" VisIt database using .visit files.

I asked Hank Childs a while back, but didn't get a reply. I now asked on the VisIt users mailing list.
