STOMP：异构多处理器调度策略评估工具
STOMP: A Tool for Evaluation of Scheduling Policies in Heterogeneous Multi-Processors
摘要：
近年来，异构芯片多处理器的激增达到了前所未有的水平。传统的同构平台在实现高性能超低功耗计算方面表现出了根本的局限性，特别是在具有实时执行期限或关键性约束的应用领域。通过将正确的通用核心和硬件加速器组合在一起，以及适当的芯片互连和存储器技术，异构芯片多处理器已成为一种有效的高性能和低功耗计算替代方案。异构架构的挑战之一涉及跨芯片中的各种选项的应用任务（进程、线程）的高效调度。因此，关键是要提供工具，使早期的原型和评估的新的调度策略的异构平台。在本文中，我们提出了STOMP（调度技术优化在异构多处理器），一个模拟器的快速实施和评估的任务调度策略在多核/多处理器系统中的一个方便的接口，以简单的方式“插入”新的调度策略。STOMP的彻底验证表现出较小的相对误差相比，在稳态分析过程中的封闭形式的等效模型。
英文摘要：
The proliferation of heterogeneous chip multiprocessors in recent years has reached unprecedented levels. Traditional homogeneous platforms have shown fundamental limitations when it comes to enabling high-performance yet-ultra-low-power computing, in particular in application domains with real-time execution deadlines or criticality constraints. By combining the right set of general purpose cores and hardware accelerators together, along with proper chip interconnects and memory technology, heterogeneous chip multiprocessors have become an effective high-performance and low-power computing alternative. One of the challenges of heterogeneous architectures relates to efficient scheduling of application tasks (processes, threads) across the variety of options in the chip. As a result, it is key to provide tools to enable early-stage prototyping and evaluation of new scheduling policies for heterogeneous platforms. In this paper, we present STOMP (Scheduling Techniques Optimization in heterogeneous Multi-Processors), a simulator for fast implementation and evaluation of task scheduling policies in multi-core/multi-processor systems with a convenient interface for "plugging" in new scheduling policies in a simple manner. Thorough validation of STOMP exhibits small relative errors when compared against closed-formed equivalent models during steady-state analysis.
