【摘要】：多核体系结构的发展,使人们可以以猜测的方式挖掘应用中的粗粒度并行,线程级猜测执行(TLS)就是其中的典型代表。它的最大优点是编程模型非常简洁——程序员只需标识出那些可以猜测执行的代码段即可,运行时系统或硬件负责确保猜测线程之间的数据相关不被破坏。全面分析了现有的TLS技术,总结了当前TLS面临的挑战和未来的主要发展趋势。主要贡献包括:1)按照猜测变量的生命周期提出了一种新的TLS技术分类方法,并比较了各种已有方法的优缺点;2)根据猜测变量的生命周期,归纳了支持TLS的多核平台的设计空间,提出了探索该设计空间的若干方法;3)指出了TLS技术当前面临的挑战和未来的发展趋势。
[Abstract]:With the development of multi-core architecture, coarse-grained parallelism in applications can be mined by conjecture, and thread level conjecture execution (TLS) is a typical example.Its biggest advantage is that the programming model is very simple-the programmer simply needs to identify the pieces of code that can be guessed and executed, and the runtime system or hardware is responsible for ensuring that the data correlation between the guessing threads is not broken.This paper analyzes the existing TLS technology, summarizes the current TLS challenges and the main trends in the future.The main contributions include: 1) A new TLS classification method is proposed according to the life cycle of the conjectured variables, and the advantages and disadvantages of various existing methods are compared. (2) according to the life cycle of the conjectured variables, the design space of the multi-core platform supporting TLS is summarized.Several methods to explore the design space are put forward. The challenges and future trends of TLS technology are pointed out.
