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.

All these estimates are for UCERF 3, estimating that the number of ruptures increases from 15000 to 200,000, but the number of rupture variations per rupture remains the same.

0.5 Hz (per site)

Number of rupture variations: 5.5 million

Deterministic

Number of jobs: 5.6 million

Storage: 40 GB SGTs, 125 GB seismograms

SUs: 12k SGTs + 26k post-processing = 38k

Broadband

Number of jobs: 16.6 million

Storage: 40 GB SGTs, 500 GB seismograms

SUs: 12k SGTs + 52k post-processing = 64k

1 Hz (per site)

Number of rupture variations: 5.5 million

Deterministic

Number of jobs: 5.6 million

Storage: 320 GB SGTs, 250 GB seismograms

SUs: 80k SGTs + 150k post-processing = 230k

Broadband

Number of jobs: 16.6 million

Storage: 320 GB SGTs, 2 TB seismograms

SUs: 80k SGTs + 200k post-processing = 280k
