Some experiences on programming of time domain boundary element in parallel processing environment

Numerical simulations of the transient dynamic response of single piles in homogenous soil under vertical loads are carried out by using the time domain boundary element method. The availability of parallel processing machine allows the programme for such analysis to be parallelized. The real time taken for computing can thus be very much reduced. This paper presents the experience gained in parallelizing the programme for the IBM 9076 Scalable Powerparallel (SP2) System. Two coarse gain and one fine grain parallelisms based on various strategies are discussed. Parallel performance results obtained in terms of speed-up and efficiency are presented to demonstrate the high level of parallelism inherent in the time domain BEM.link_to_subscribed_fulltex
