一般注記A new array data assignment technique, to be used in CFD (Computational Fluid Dynamics)simulations on massively parallel processor is presented. The implenentation was done for an H2P parallel processor. H2P is an MIMD (Multiple-Instructions Multiple-Data stream) type of parallel processor in which every processing element (PE) has a local memory (i.e. a distributed-memory parallel processor) and a vector facility. The main contribution of this paper is in proposing an original data assignment technique which leads to an efficient use of the vector facilities. The proposed data assignment technique uses a combination of two methods (referred to as SWAP and Wave Front in the paper) in order to achieve its purpose, an efficient use of the vector facilities. The original CFD program is modified into a parallelized one, by applying the proposed methods. It is shown that, in running this modified program, H2P (in a 512 PEs configuration) can achieve a 180 times speedup over the original CFD program running on a uniprocessor (using the same type of PE).
