To achieve the best performance on modern computers, one mustunderstand and exploit the interactions between program behavior,run-time systems, and hardware. This research explores compiler andrun-time system support for improving load-value prediction and forreducing the energy consumption of programs. Load-value predictionexposes instruction-level parallelism in programs by allowing loads toexecute in parallel with the instructions that depend on it. Energyreduction techniques reduce the energy requirements of programswithout significantly degrading performance.Broadly speaking this research considers two kinds of techniques: (i)Compiler techniques that use easily-available information in programs(such as type information) to transform or annotate code to makebetter use of hardware; (ii) Run-time system techniques thatreorganize and annotate data to make better use of hardware. Thisresearch will also consider new hardware mechanisms for load-valueprediction and energy consumption that can be exploited in software.

为了在现代计算机上实现最佳性能，必须理解并利用程序行为、运行时系统和硬件之间的相互作用。本研究探索编译器和运行时系统的支持，以改善负载值预测和减少程序的能耗。负载值预测通过允许负载与依赖于它的指令并行执行，从而暴露了程序中的指令级并行性。节能技术在不显著降低性能的情况下降低了程序的能源需求。总的来说，这项研究考虑了两种技术：(i)编译器技术，它使用程序中容易获得的信息（如类型信息）来转换或注释代码，以更好地利用硬件；重新组织和注释数据以便更好地利用硬件的运行时系统技术。本研究还将考虑可在软件中开发的用于负载值预测和能耗的新硬件机制。
