Macroscopic friction response of rotational and non-rotational lattice solid gouge models in 2D and 3D

Parallel computing architectures, such as the SGIAltix 3700 super-cluster, provide the opportunity to solve large computational problems. In order to take advantage of high performance systems, a Message Passing Interface version of the LSM has been implemented (Abel et al. 2004). Recent benchmarks demonstrated an 80% parallel efficiency for the parallel LSM on 128 processors of the SGI Altix 3700 (Latham et al. 2004).
