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

1. M8 simulation computational scale has a combined outer/inner scale of 10 ^ 4.3 (810km/40m)
2. M8 science run using SCEC's AWP-ODC software achieved sustained performance on real science problem for 24 hours in excess of 220Tflop/s. When the M8 simulation was run in April, 2010, no other seismic code had achieved more than 100Tflop/s.
3. M8 wave propagation simulation run on NCCS Jaguar used more cores (220,000) and processors (xxxx). No other seismic wave propgation application has be used to do real science runs using more cores than M8.
4. The M8 simulation software, SCEC's AWP-ODC, scaled nearly perfectly up to 223k cores
5. M8's input velocity mesh required 435 billion grid points. We are not aware of any simulations at this size.

The M8 Project is lead by Yifeng Cui, Kim Olsen, and Thomas H. Jordan.
