Abstract

In the last 40 years, advances in structural analysis such as the finite element method (FEM) have paralleled the advances associated with modem high-speed digital computers. What should have been a significant step in the evolution of computational structural analysis was the introduction of parallel processing. Initially, parallel processing was developed for large mainframes and supercomputers. More recently, the emphasis in parallel processing research has shifted towards clusters of workstations and personal computers (PC's). However, the complaint of many researchers is that while parallel processing is becoming reality, many engineering disciplines, (including structural analysis), are lagging behind in the use of this new computer technology. The work presented here was specifically designed to exploit the technology of parallel processing, and in particular, the use of clusters of PC's. A space frame code has been modified to analyze three-dimensional, multi-bay structures using parallel processing on PC's operating under the Linux operating system. As expected, the decrease in processing time is significantly improved as the size of the structure and the number of computers are increased. Several different models have been analyzed on multiple combinations of parallel PC's. For a common basis, all results are compared to the runtimes of the models on a single PC. Reduction factors (or speed up) ranging from 1.2 to 3 and higher have been achieved. This paper outlines the details of the development and results of this parallel processing work. In addition, efforts to move the code and assess the results on the more popular Windows NT operating system will also be outlined.
