[Vis5d-users] Still no luck with > 2 GB vis5d files

Well, I spoke too soon. I did create a > 2 GB vis5d file after tweaking
the code, but much of the animation is garbage, starting at the point
at which I'd assume the 2 GB mark is hit. The values of the variable
being viewed are reasonable but the isosurfaces are very strange and
jump around from frame to frame.

I'm kind of at a loss as of what to do at this point.

Could someone who has created > 2 GB vis5d files on the SGI platform
(I'm on the NCSA Origin) please let me know what compiler options to
pass to make this work.  The utility I use to create the vis5d files
borrows v5d.c, binio.c, config.h, binio.h and v5d.h from vis5d, creates
object code from them, and links at the end. Does the vis5d application
also need any special compiler options to view these large files?

Also, to LAM SAI-LAP, who had luck with creating > 2GB vis5d files under
Linux using gcc, I'm wondering what use the -D_FILE_OFFSET_BITS=64
and -D_LARGEFILE_SOURCE options are since none of the vis5d 5.2 code
contains those preprocessor variables!
