High level parallelism in hierarchy of GPST algorithm for parameter identification in engineering mechanics

Abstract The Generalized Pulse-Spectrum Technique (GPST) is a versatile and efficient iterative numerical algorithm for solving multi-parameter idenitification problems in engineering which can be formulated mathematically as multi-parameter inverse problems of a system of partial differential equations. Here high level parallelism is introduced into the hierarchy of GPST. By using a simple computational complexity analysis, it is shown that very large speedup with no communication overhead can be achieved even without the introduction of low level parallelism into the hierarchy of GPST. Moreover, the parallel structured GPST can achieve considerable speedup over the standard GPST even on a single-processor computer.
