A Parallel Implementation of the Lattice Solid Model for the Simulation of Rock Mechanics and Earthquake Dynamics

摘要: — The Lattice Solid Model has been used successfully as a virtual laboratory to simulate fracturing of rocks, the dynamics faults, earthquakes and gouge processes. However, results from those simulations show that in order make next step towards more realistic experiments it will be necessary use models containing significantly larger number particles than current models. Thus, require greatly increased amount computational resources. Whereas computing power provided by single processors can expected increase according “Moore’s law,” i.e., double every 18–24 months, parallel computers provide today. In this available for simulation microphysics earthquakes, version implemented. Benchmarks using large with several millions have shown implementation achieve high parallel-efficiency about 80% numbers on different computer architectures.
