基于面向方面和运行时反射技术的并行框架

针对使用并行库JOMP的程序在性能方面存在的不足,提出一个可以分离并行逻辑和功能逻辑的并行框架。该框架对程序中需要并行处理的部分进行标记,采用面向方面和运行时反射技术实现被标记部分的处理,其中面向方面技术用于实现并行逻辑的分离和编织,运行时反射技术用于获取运行时被标记部分的相关信息,以并行库(waxberry)的方式实现了该并行框架。使用基准测试程序JGF套件中的三个测试程序对并行库进行了测试,实验结果表明,应用该并行库的程序可以获得较好的性能。

Parallel framework based on aspect-oriented programming and run-time reflection

JOMP that is the OpenMP-like implementation in Java needs to be optimized, so a parallel framework, which can separate parallel logic and logic function, was proposed.The parallel framework was implemented by a parallel library named waxberry, and the parts which need to be processed parallelly were annotated and executed by using Aspect-Oriented Programming (AOP) and run-time reflection. AOP was used to separate parallel parts with core ones, and to weave them together. Run-time reflection was used to obtain the related information during the parallel execution. The library waxberry was evaluated using Java Grande Forum (JGF) benchmarks on a quad-core processor. The experimental results show that the waxberry can obtain good performance.
