Research on Efficiency of Parallel Computing in CPU+GPU Hybrid Mode
Luan Jiang-xia · Computer and Modernization · 2012
CPU+GPU hybrid mode,comparing to traditional supercomputing architectures,is more cheaper and more environmentally friendly,low-carbon.Thus the people pay more attention on it.There are more and more systems which rank on World HPC Top500 using CPU+GPU hybrid mode.However,the efficiency of heterogeneous parallel mode is too low.This article based on the principle of parallel schedule of hybrid mode,takes Linpack test as an example to explain the method of getting a higher efficiency of parallel computing.
