SHF:Small:Multicore Hardware/Software CoDesign using Fast, Cycle-Accurate Simulators

调整软件以提高性能/功耗通常非常困难，因为人们无法以精细的时间分辨率轻松观察运行硬件的整个内部工作和功耗。 因此，确定性能和功耗问题的根本原因往往只能通过精心制作的实验代码，运行该代码，并测量有限的信息，可以观察到，这项拟议中的研究旨在设计一类新的非常快速和准确的模拟器，与适当的仪器，可以提供显着更多的可见性比建模硬件。 然而，这样的模拟器可能会导致信息过载，使发现问题变得困难。因此，PI建议研究有效和自动发现此类问题的方法，以便更快更容易地解决这些问题。 这些方法可以产生更高效的计算机系统，可以更快地解决问题和/或使用更少的能量，潜在地影响硬件和软件开发人员以及用户。

Tuning software for improved performance/power is often extremely difficult because one cannot easily observe the entire inner workings and power consumption of running hardware at a fine time resolution. Thus, determining the root cause of performance and power issues can often only be done by careful crafting of experimental code, running that code, and measuring the limited information that can be observed.This proposed research is aimed at designing a new class of very fast and accurate simulators that, with proper instrumentation, can provide significantly more visibility than the modeled hardware. However, such simulators can result in information overload, making finding the issues difficult. Thus, the PI proposes to investigate methods to effectively and automatically find such issues so that they can more quickly and easily be addressed. Such methods could result in more efficient computer systems that can solve problems faster and/or use less energy, potentially impacting hardware and software developers and users alike.
