【Abstract】 Heterogeneous computing has been widely introduced in high performance scientific computing as well as in “general purpose” applications due to its higher performance cost ratio.However,the application program is difficult to develop because heterogeneous parallel programming and performance analysis are still empirical.In this paper,Heterogeneous Bulk Synchronous Parallel (HBSP) model is proposed and its cost model is derived.The message passing protocol of HBSP is designed and realized in all kinds of machines which support MPICH package.The FFT algorithm is studied as an example and the experimental results of FFT in several heterogeneous systems are discussed.更多还原
