Abstract
The Defence Research Establishment makes extensive use of the TASCflow computational fluids software (CFD) package from Advanced Scientific Computing to support research programs in Military Engineering and Bio-Chemical Hazard assessment. CFD can be computationally intensive when large integrated 3D problems are calculated. For this reason, DRES acquired a DEC 8400 multi-processor workstation with 10 CPU's and 4 GB of memory. This machine is intended to allow problems to be computed in parallel on several processors to speed up the overall performance of the computations. DRES has contracted ASC to develop and apply TASCflow3D in a parallel environment under contract number W7702-6-R587/01/EDM. The parallel version of TASCflow was intended to be installed on the DEC 8400 machine. However, near the end of the contract, a request was made by the Scientific Authority to transfer the installation from the DEC 8400 machine at DRES to the DREV site. DREV utilizes a cluster of four Sun Ultra Sparc machines, linked together by a common network. Thus, this development has been adjusted to accommodate this installation change. The report describes the parallelization algorithm and the manner in which it has been applied on a cluster of workstations. Expected performance on both multiprocessor workstations and a workstation cluster are postulated.
