CyberShake Study 2.3

CyberShake Study 2.3 is a proposed study to calculate hazard curves under CyberShake 1.5 using CVM-S and CVM-H with the RWG V3.0.3 SGT code and AWP-ODC-SGT, and the Graves and Pitarka (2010) rupture variations. The goal is to calculate the same Southern California site list (281 sites) as for past CyberShake studies so we can produce comparison curves and maps, and understand the impact of the SGT codes and velocity models on the CyberShake seismic hazard.

Computational and Data Estimates

We are planning to use Blue Waters, Stampede, and Kraken for this calculation. We plan to calculate 281 sets of 2-component SGTs for each of RWG CVM-S, RWG CVM-H, AWP CVM-S, AWP CVM-H for a total of 1124 sets of SGTs.

We estimate the following requirements for each system:

Blue Waters

Use for AWP SGT calculations

562 sets of AWP SGTs x 5000 SUs/set = 2.8M SUs
562 sets of AWP SGTs x 40 GB/set = 22.0 TB

Stampede

Use for RWG SGT calculations and RWG post-processing

562 sets of RWG SGTs x 3900 SUs/set = 2.2M SUs
562 sets of RWG SGTs x 40 GB/set = 22.0 TB

No numbers yet on Stampede post-processing.  SGT calculations were about 4x faster on Stampede than Kraken.  If we assume we can get 2x improvement:
562 sites x 2750 SUs/site = 1.5M SUs
562 sites x 11.6 GB/site = 6.4 TB output data (seismograms, spectral acceleration)

Total:  3.7M SUs, 28.4 TB

Kraken

Use for AWP post-processing

562 sites x 11.6 GB/site = 6.4 TB output data (seismograms, spectral acceleration)
562 sites x 5500 SUs/site = 3.1M SUs

SCEC storage

1124 sites x 11.6 GB/site = 12.7 TB stored output data
1124 sites x 4.9 GB/site = 5.4 TB workflow logs
