摘　　要：随着单机性能的不断提高、网络技术和并行编程环境的发展,基于网络的并行计算模式正日益成为高性能计算的主要模式,并得到越来越广泛的应用。网络计算使得计算资源进一步得到共享,也带来了使用他人计算资源时的费用问题。传统单机计算模式的计费系统已不适合网络并行计算环境的计费。该文提出了一种适合网络并行计算环境的计费方法,该方法充分考虑了网络计算中使用计算资源的各个因素,适应不同的计费规则,具有很强的普遍性。随着网络计算环境的进一步普及,该方法有更广泛的应用前景。With the devel op ment of the performance of a single computer,the network technology,and the p arallel pro-gramming environment ,the network_based parallel computing is bec oming the main mode of high performance comput-ing,and will be widely applied .The mode of network computing makes the computing resource being more and more shared.Thus it makes the problem of the charge when using the computing resour ce of someone else.The traditional ac-count system based on single computing mode is not fit for network parallel computing environment.In this paper,a new account method for the network parallel computing environment is introduced. The method sufficiently considered most possible factors when using network para llel computing resource,and it can be accommodated according to different ac-count rules.So,the method is universal.With the network parallel computing e nvironment becoming more and more preva-lent ,the method has more extensive a pplication future.
