CyberShake simulation specifications

This page is to gather and document the development of a specifications file, generated by the DAX generator and consumed/augmented by workflow stages, which tracks specification information about a CyberShake run. The concept is that having this will simplify reproducibility of previous CyberShake results.

Specifications to track

This is a list of specifications to track, along with the number and type of data, and what is consumed/produced by each step.
