Silo?

Silo is a "mesh and field I/O library and scientific database" which VisIt uses to read in data. As such it is an interesting thing for my data, especially for adaptive mesh refinement (AMR) data. I am torn between two options. Option one: Invent my own file format that does what I want and nothing more, though that will require me to write a plugin for VisIt to actually read the data then. Option two: Produce files that VisIt can read directly but hence enforcing a bunch of dependencies on my code.

In either case it is going to be a pain, so to estimate one side of the pain I was going to play around with Silo a bit. But I keep on not finding the sources, so once and for all (until they change the web site) here is the link: Silo.
