基于工作流网的分布式作业管理系统性能分析方法

A Method of Distributed Job Management System Performance Analysis Based on Workflow Net

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 arc differences of processing capability, coupled with the different resources required in the different task, in theory, the refer- ence 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 perform- ance, it provides the theoretical feasibility analysis for the reliability of software functions on system, and ensures that the basic methodology support on subsequent development.
