基于工作流网的分布式作业管理系统性能分析方法

摘要

在分布式环境中,各节点本身配置不同和资源的数量多少,导致在处理能力上也有差别,再加上不同作业所需资源的不同,理论上难以精确地计算出系统性能参考值.鉴于此,本文基于已开发的分布式作业管理系统软件,利用WF_net的原理着重分析与研究作业流等价性能,进而推出系统负载性能评估方法,以进一步有效地评估分布式环境下作业调度的合理性与高性能性,并提供了具有参考价值的系统性能量化值,为系统软件功能的可靠性做好理论可行性分析,确保后续开发有据可依.%In a distributed environment, each node itself has a different configuration, resource quantity, resulting in that there are differences of processing capability, coupled with the different resources required in the different task, in theory, the reference value of system performance is difficult to be accurately calculated. In view of this, based on the developed distributed job management system software, using the principle of WF_net, the paper analyzes and researches the equivalent performance of JNW and launches the assessment methods of workload on the system, in order to further effectively assesses the rationality and high-performance of job scheduling in the distributed environment. With putting a quantized reference value of system performance , it provides the theoretical feasibility analysis for the reliability of software functions on system, and ensures that the basic methodology support on subsequent development.
