Lei Yang · Journal of Liaoning Technical University · 2011
To solve the problem of the communication overhead and synchronous overhead increase in electron charge distribution calculation of ABEEM model,this study applies Linux parallel computing system communication to develop a system layer zero copy communication optimization method based on Cholesky decomposition parallel algorithm in communication process.In addition,a LKM module,which can be removed,is developed to shorten development time and test time,and reduce data copies based on the address mapping zero copy technology.It has solved the problem of communication delay.The study results show that the communication optimization method developed based on zero copy technology can achieve a timely,efficiently and accurately data communication and greatly improve the performance of Cholesy decomposing parallel algorithm.
