Parallel solid mechanics codes at Sandia National Laboratories
Computational physicists at Sandia National Laboratories have moved their production codes to distributed memory parallel computers. Such an effort required the development of parallel algorithms, parallel data bases and parallel support tools. The Eulerian CTH code was rewritten. Moving both ALEGRA and PRONTO to parallel computers required only a modest number of modifications. It involved restructuring the restart and graphics data bases to make them parallel and minimize the I/O to the parallel computer. It also involved developing mesh decomposition tools to divide a rectangular or arbitrary connectivity into sub-meshes. It also involved developing new visualization tools to process the very large, parallel data bases. This paper also discusses Sandia's experiences running these codes on its 1840 compute node Intel Paragon, 1024 processor nCUBE and networked stations.
