Abstract

The increasing number of cores integrated into modern processors is blurring the line between supercomputers and enterprise-grade servers. Therefore, the same attention to lock contention bottlenecks must be given to Java-based business workloads as it is given to massively parallel, high-performance computing applications, especially when it comes to characterizing global trends that would ease the transition of today's code base to tomorrow's parallel configurations. This paper first presents the characteristics of a typical Java-based business application software stack and examines the locking contentions that can appear at each level of that stack. Second, it presents scalability evaluation of three enterprise-grade, Java-based workloads and details the lock contention founds. Third, it summarizes the results of our findings, emphasizing the need for a streamlined methodology for lock-contention analysis of enterprise Java workloads.

企业Java工作负载中多核可伸缩性瓶颈的评估

集成到现代处理器中的核心越来越多，这模糊了超级计算机和企业级服务器之间的界限。因此，对于基于java的业务工作负载，必须像对大规模并行、高性能计算应用程序一样，对锁争用瓶颈给予同样的关注，特别是在描述能够简化当前代码库向未来并行配置过渡的全球趋势时。本文首先介绍了典型的基于java的业务应用程序软件堆栈的特征，并检查了可能出现在该堆栈的每个级别上的锁争用。其次，介绍了三种企业级、基于java的工作负载的可伸缩性评估，并详细介绍了锁争用的发现。第三，总结了我们的研究结果，强调需要一种简化的方法来分析企业Java工作负载的锁争用。
