CyberShake Study 15.3 is a computational study to calculate one physics-based probabilistic seismic hazard model for Southern California at 1 Hz, using CVM-S4.26, the GPU implementation of AWP-ODC-SGT, the Graves and Pitarka (2015) rupture variations with uniform hypocenters, and the UCERF2 ERF. The SGT calculations will be split between NCSA Blue Waters and OLCF Titan, and the post-processing will be done entirely on Blue Waters. The goal is to calculate the standard Southern California site list (286 sites) used in previous CyberShake studies so we can produce comparison curves and maps, and data products for the UGMS Committee.

Preparation for production runs

  1. Get DirectSynth working at full run scale, verify results
  2. File ticket for 90-day purged space at Blue Waters
  3. Follow up on high priority jobs at Titan
  4. Work out interface between Titan workflows and Blue Waters workflows
  5. File ticket for reservation at Blue Waters, along with justification
  6. Finish test of 1 Hz simulation with 2 Hz source
  7. Update DAX to support separate MD5 sums
  8. Add MD5 sum job to TC
  9. Check list of Mayssa's concerns
  10. Run test of full 1 Hz SGT workflow on Blue Waters
  11. Evaluate topology-aware scheduling
  12. Add restart capability to DirectSynth
  13. Add cleanup to workflow
  14. Simulate curves for 3 sites with final configuration; compare curves and seismograms
  15. Look at how to create study description file
  16. Modify workflow to have md5sums be in parallel
  17. Add a third pilot job type to Titan pilots
  18. Science readiness review
  19. Technical readiness review

Computational Status

We are hoping to begin this study in early March.

A comparison of 1 Hz results with SeisPSA to results with DirectSynth for WNGC. SeisPSA results are in magenta, DirectSynth results are in black. They're so close it's difficult to make out the magenta.
