摘要

本文提出了一种在工作站的异构网络中独立于所使用的系统来评估CPU功率的方法。它基于Java语言的使用,以确保应用程序的可移植性,特别是基于Sun Java版本1.5中引入的线程CPU处理时间度量机制。该工具将集成到负载平衡机制中,该机制完全用Java编写,并由我们在LIFL项目ADAJ中开发。我们展示了如何用一个完全用Java编写的软件来评估CPU的潜在能力。此外,我们将证明我们的方法所提供的结果。我们还将分析校准工具的开发,以便在工作站网络负载平衡的背景下改善并行和分布式应用程序的执行时间。

A Java CPU calibration tool for load balancing in distributed applications
This article presents a method for evaluating the CPU power, independently from the system used, in heterogeneous networks of workstations. It is based on the use of Java language in order to ensure application portability and more particularly on the mechanism of thread CPU processing time measurement introduced in the version 1.5 of Sun Java. That tool will be integrated into the load balancing mechanism which is totally written in Java and that we developed in the LIFL project ADAJ. We show how to evaluate the potential power of the CPU with a software totally written in Java. Moreover, we will justify the results provided by our approach. We will also analyse the exploitation of the calibration tool in order to improve the execution time of parallel and distributed applications in the context of load balancing in a network of workstations.
