基于TORQUE的高性能计算平台记账系统

TORQUE-BASED ACCOUNTING SYSTEM FOR HIGH-PERFORMANCE COMPUTING PLATFORM

高性能计算已成为继理论研究和实验科学之后的第三种科研方法。如何高效地利用高性能计算平台上众多的设备为科研提供有效服务是管理者需要面对的主要问题。主要介绍基于开源软件TORQUE的高性能计算平台记账系统的设计与实现,包括计算算法、系统架构、主要功能模块、数据设计及代码实现。通过归纳法分析TORQUE日志记录模式,给出从作业角度和资源角度进行资源使用率的计算方法。该记账系统架构划分为五层,系统具有很好的灵活性和开放性,可以很容易地移植到其他平台或者其他类型的作业调度系统上。该系统更着重于当前资源的使用情况、用户资源使用情况、任务等待时间,而非简单的费用计算和账单打印,所以它更能为管理者和决策者提供有效且强大的数据支撑。

High-performance computing has become the third scientific research method following the theoretical research and experimentalscience. How to efficiently utilise numerous devices on high-performance computing platform to provide effective services for scientificresearches is a major problem faced by the managers. This paper mainly introduces the design and implementation of a TORQUE-basedaccounting system for high-performance computing platform, which includes the computational algorithm, the system architecture, the mainfunctional modules, the data design and the code implementation. Through analysing the logging mode of TORQUE with induction it presentsthe calculation method of resource utilisation from the prospective of jobs and resources. The architecture of accounting system is divided intofive levels and the system has good flexibility and openness, which can be easily ported to other platforms and other kinds of job schedulingsystems. The system focuses more on the usage of current resources, user, s resource utilisation and task waiting time rather than the costcalculation and bill printing, so it can provide more effective and powerful data support for administrators and decision-makers.
