Focussing on those areas of simulation which dominate the large-scale computational requirements within the automotive industry, the initial aim of the paper is to give an insight into typical applications and algorithms being used. Beyond this, the main emphasis will be on the more recent developments related to the take-up of HPC technology in the form of the distributed-memory, message-passing programming paradigm. Examples will be taken from commercial applications codes involved in the ESPRIT porting action EUROPORT.
The main emphasis of the lecture is on the recent developments within automotive simulation codes related to the take up of HPC technology in the form of the distributed-memory, messagepassing programming paradigm. Included within the presentation of parallelization strategies and attained performances will be overviews of typical applications and algorithms. Given the large range of applications areas, it is not possible to address all simulation codes or algorithms being used in the framework of a single lecture. Thus, this lecture focusses its attention in two ways:
. On two of those areas of numerical simulation which could be classed as “classical” applications within the automotive industry – Computational Fluid Dynamics (CFD); crash simulation; Linear Statics and Normal Modes analyses.
. On commercial applications codes which have recently moved to parallel, distributed computing and which were involved in the recent ESPRIT porting action
