Abstract
Along with quad-core PC coming into the market and invention of 80-core processor in the laboratory, Software development will go through a foundational innovation due to multicore technology. The technique of parallel programming on multi-core computers is explored in this thesis. First, the OpenMP standard which is an application programming interface (API) on parallel programming model of shared-memory is introduced and an overview of a set of compiler directives and a library of support functions are given. The OpenMP programs requires an OpenMP-compatible compiler and thread-safe libraries，therefore, both Intel C++ compiler 9.1 and Microsoft Visual Studio 2005 are perfect choices. Then, two-dimensional discrete fast Fourier transform (FFT) is studied by focusing on parallel program design，realization and optimization technology. Finally，the thesis predicts that high performance parallel computing software component library must be a perfect exploitation field in the further future.
