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

Stations in Station List by rupture
-------------------
Mw6.0: 105
Mw6.5: 117
Mw7.0: 163
Mw7.5: 175

------------------
Seismograms per run (stations * variations):
Mw6.0: 105 * 9  =  945
Mw6.5: 117 * 9  = 1053
Mw7.0: 163 * 11 = 1793
Mw7.5: 175 * 11 = 1925
------------------
Total:            5716 seismograms per run

Total Seismograms = 36*5716 = 205,776

Runtime Estimates:
 
(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
