CyberShake Computational Estimates
We will describe or current best estimates for the CyberShake computational and data requirements as we progress in our simulation planning and testing. These estimates will help us identify which aspects of the CyberShake computational system needs to be optimized to work within our time and resource constraints.
The UCERF 3 estimates assume that the number of ruptures increases from 15,000 to 350,000, but the number of rupture variations per rupture on average remains the same.

Future SCEC data needs
These are estimates of CyberShake storage required on SCEC computers for upcoming runs.
July-August 2013: 6.1 TB to archive (0.5 Hz, CVM-SI, 2 SGT versions, 286 sites, UCERF 2) Fall 2013: 12 TB (1 Hz, 286 sites, 2 combinations, UCERF 2) Spring 2014: 45 TB (0.5 Hz, 286 sites, 1 combination, UCERF 3)
UCERF 2
