The CFD Group has been involved with parallel processing and facility development for a number of years in its pursuit of tackling real engineering problems in aerodynamics. An in-house developed code for solving the unsteady Navier-Stokes equations, PMB (parallel multiblock), has been developed by the Group for implementation on distributed memory parallel computing environments. During the code development, the group has used clustered UNIX workstation and PC clusters, that it has developed, as well national parallel computing facilities. The components of the Beowulf clusters developed have been chosen on cost/performance and appropriateness for the applications. The talk will emphasise the experience on the use of its latest Beowulf facility, involving 32 750MHz AMD Athlon PCs with 16 GB overall memory, to tackle some industry based problems.
