Applied Mathematics Seminar

The availability of powerful desktop workstations makes it possible to build relatively cheap parallel computing facilities using off the shelf components. Using parallel software with these facilities allows the simulation of complex 3 D flows in reasonable compute times. The performance of a recently installed cluster based on Pentium 4 machines with a 100Mbit/s switch using message passing and data parallel software will be discussed. The details of a time-accurate Navier-Stokes solver coded in High Performance Fortran will be presented with, in particular, a comparison of the accuracy of the solver on staggered and non-staggered grids. Results obtained using this solver for two layer mixing flow will be presented.
