Broadband Hanging Wall Simulation
This Wiki page describes the simulations that will be performed on the Broadband Platform to investigate footwall / hanging wall and directivity effects for NGA-W2. This simulation is expected to generate 205,776 3-component seismograms.

Hanging Wall Specifications
Robert Graves has written a specification for a set of footwall and hanging wall simulation in this document.
Computational Estimates
40 Scenarios per code base 36 Code base combinations
5716 Seismograms per simulation 1440 Simulations 205,776 Total seismograms 729 days Total runtime
Seismograms per run (stations * variations): Mw6.0: 105 * 9 Mw6.5: 117 * 9 Mw7.0: 163 * 11 Mw7.5: 175 * 11
Total: 5716 seismograms per run
Total simulation: 40*18*2 = 1440
Total Seismograms = 36*5716 = 205,776
Runtime: (6.0 40 mins, 6.5 2 hrs, 7.0 8 hrs, 7.5 34 hrs) Mw6.0: (9*36) runs *40 mins = 216 hrs Mw6.5: (9*36) runs *2 hrs = 648 hrs Mw7.0: (11*36) runs *8 hrs = 3168 hrs Mw7.5: (11*36) runs *34 hrs = 13464 hrs
Total runtime (1 core): 729 Days
