CyberShake Study 22.12
From SCECpedia
CyberShake Study 22.10 is a proposed study in Southern California which will include deterministic low-frequency (0-1 Hz) and stochastic high-frequency (1-50 Hz) simulations. We will use the Graves & Pitarka (2019) rupture generator and the high frequency modules from the SCEC Broadband Platform v22.x.

Production Checklist
Science to-dos
- Determine which validation events need to be completed before the study
- For each validation event, calculate BBP results, CS results, and CS results with BBP Vs30 values
- Decide if we should stick with rvfrac=0.8 or allow it to vary
- Determine appropriate SGT, low-frequency, and high-frequency seismogram durations
- Update high-frequency Vs30 to use released Thompson values
Technical to-dos
- Integrate refactoring of BBP codes into latest BBP release
- Switch to using github repo version of CyberShake on Summit
- Update to latest UCVM (v19.4)
- Switch to optimized version of rupture generator
- Test DirectSynth code with fixed memory leak from Frontera
- Switch to using Pegasus-supported interface to Globus transfers
