Abstract
AbstractIn this paper, we describe our experience of creating an OpenMP implementation of Bit-reversal for Fast Fourier Transform programs from the existing un-parallelizable sequential algorithm. The aim of this work is to present an analysis of a case study showing the development of a shared memory parallel Bit-reversal for the FFT parallel code with practical and efficient use of multi-core machines. We present our implementation and discuss the results of the case study in terms of program improvement that may be needed to help parallel application developers with similar high performance goals. Our preliminary studies, results and experiments based on FFT code running on a four 4-cores Intel Xeon64 CPUs /Dell 6850 platform. The experimental results show that the performance of our new parallel code on 16 cores shared-memory machine are promising.KeywordsShared-memory parallel programmingOpenMPBit-reversalFFT
