SCEC M8 Simulation

The SCEC M8 Simulation involved a very large dynamic rupture, run on NICS Kraken in March, 2010, and a very large and earthquake wave propagation simulation, performed on NICS Jaguar in April 2010. The M8 simulation represented the largest earthquake wave propagation simulation in several categories including:

M8 can be described as the largest earthquake wave propagation simulation for following reasons:

1. The simulation computational scale for the SAF area with a combined outer/inner scale of 10 ^ 4.3 (810km/40m)
2. FLOPS, no other seismic code achieved more than 100Tflop/s so far.
3. processor cores used, no other seismic apps use so many cores
4. scalability, nearly perfectly up to 223k cores
5. grid points, 435billion. We are not aware of any simulations at this size.
