For optimal performance, you need a machine with 2 or 3 times as much
memory as your file size, plus comensurate processor and graphics
speed. For a 2.4 GB file, this also means a 64-bit architecture and OS.

For minimal performance, you may be able to get away with 1 GB of memory.
However, the standard versions of Vis5D may have trouble with a 2.4 GB
file.

I'm afraid I don't have any personal experience running Vis5D with such
large files. But the NCAR folks on this list do, so hopefully they can
give you some more practical advice. I think they have a special
version of Vis5D for 64-bit architecture and files (i.e., files longer
than 2 GB). I don't know if their big data support is built into the
current Vis5d+, or if you have to obtain it from NCAR. Good luck.

Cheers,
Bill
