A Study of LS-DYNA Implicit Performance in MPP

LS-DYNA models for Implicit Mechanics are getting larger and more complex. We are continually seeing models where the linear algebra problems in Implicit Mechanics have 10M rows and know of at least one that is nearly 40M rows. We expect users wanting to routinely solve problems with 30M very soon. It is these very large linear algebra problems that distinguish the computer requirements for Implicit Mechanics. This paper will present a study of the performance of the MPP implementation of implicit mechanics in LS-DYNA examining such issues as performance, speed-up, and requirements for computer configuration.
