Overview

A series of simulations modelling the La Habra 5.1 event will be performed on ORNL Titan with in order to address these scientific and computational goals:

  • Demonstrate that Hercules-GPU software is in production status and evaluate its performance versus the CPU version
  • Evaluate goodness of fit for synthetic waveforms versus observed at 1.0 Hz, using Po Chen's updated CVM-S4 velocity model as the material properties source for the simulation.
  • [Optionally] Validate the simulation results generated by Hercules-GPU and AWP-GPU
