Abstract

This present paper proposes the recent developments in parallel computations via a single analysis code of a unified family of generalized integration operators [GInO] for non-linear structural dynamics. The focus of this research is on the development of coarse-grained parallel computational models via generalized time integration operators that be can ported to a wide range of parallel architectures using a message-passing paradigm (using MPI), graph partitioning techniques and domain decomposition techniques. The coarse-grained parallel computational models inherit two important scalable properties: numerical scalability and parallel scalability. The numerical scalability analysis is conducted via an integrated unified technology for large deformation, elastic, elastic-plastic dynamic response. For geometric non-linearity a total Lagrangian formulation and for material non-linearity elasto-plastic formulations are employed. Serial and parallel performance results on the SGI Origin 2000 system are reported and analyzed for practical structural dynamics problems. This is the first time that such a capability is plausible via a unified technology and the developments further enhance computational structural dynamics areas.
