研究项目

  • Java的NVM原生支持: 非易失性内存(NVM)模糊了内存与持久性存储之间的界限,而Java缺乏对于NVM的高效支持,无法充分利用其大容量、低时延、持久化的特征。本项目为Java提供了NVM原生支持,研究结果包括:
    • Java语言及运行时扩展(Espresso)
    • 延迟持久化模型探索(GCPersist)
    • NVM带宽友好的垃圾回收算法(NVM-friendly-GC)
    • 轻量级对象置放策略(GCMove)
  • 垃圾回收优化: 垃圾回收是语言运行时的重要组成部分,其行为与应用性能息息相关。我们针对交互式服务、大数据分析、数据库等不同类型应用的内存行为提出了针对性的垃圾回收优化算法,其中部分成果已被OpenJDK接收并进入主线:
    • 面向交互式服务的高吞吐低时延垃圾回收器(Platinum)
    • 高可扩展全堆垃圾回收算法(ScissorGC)
