Abstract

Parallelization promises to allow increasing performance demand from users of scientific computation codes. In this article we discuss implementation of parallelization techniques in industrial computation codes for applications in Fluid Mechanics (N3S) and Structural Mechanics (Code_ASTER). We outline the gains afforded by parallelization on a Cray C98 machine in production mode, using a single version of the program running in sequential or in parallel mode, with minimum modifications to the initial code. Parallelization is applied at the discretion of the user, for whom no specialist knowledge of this technique is assumed.
