Abstract

The emergence of many-core processors raises novel demands to system design. Power-limitations and abundant parallelism require for efficient and scalable run-time management. The integration of dedicated hardware to enhance the performance of the run-time management system is gaining an increasing importance. But the design of a run-time manager for many-core generally suffers from exhaustive evaluation time. Previous works do not address for the required flexibility or do not address for reasonable evaluation time of the simulation framework. We propose the novel simulation framework Agamid to foster the development and evaluation of hardware enhanced run-time management for many-core. Our transaction-level framework performs design point evaluation of hardware enhanced run-time management for many-core at the timescale of seconds. We use a hybrid simulation approach considering the run-time management and the user application at different levels of abstraction. The framework provides a generic run-time manager to compare arbitrary management systems and HW/SW partitionings. The implementation of the run-time manager facilitates direct execution at the host machine and a detailed synchronization model. Agamid applies user application workloads by means of transaction-based task graphs. An extendable system-call interface allows arbitrary interaction between the user application and the run-time management system. The thorough calibration of the RTM timing model enables reasonable approximations of the management overhead. Our evaluation considers the accuracy, wall-time and design space exploration capabilities of Agamid. Our findings substantiate the usefulness to integrate the modeling of the run-time management, hardware architecture and user application into a single transaction-level framework.

Agamid设计空间探索框架

多核处理器的出现对系统设计提出了新的要求。功率限制和丰富的并行性需要高效和可伸缩的运行时管理。集成专用硬件以提高运行时管理系统的性能正变得越来越重要。但是多核运行时管理器的设计通常会受到详尽的评估时间的影响。以前的工作没有解决所需的灵活性或没有解决模拟框架的合理评估时间。我们提出了一种新的仿真框架Agamid，以促进多核硬件增强运行时管理的开发和评估。我们的事务级框架在秒级时间尺度上执行多核硬件增强运行时管理的设计点评估。我们使用混合模拟方法，考虑运行时管理和用户应用程序在不同的抽象层次。该框架提供了一个通用的运行时管理器，用于比较任意管理系统和硬件/软件分区。运行时管理器的实现促进了在主机上的直接执行和详细的同步模型。Agamid通过基于事务的任务图应用用户应用程序工作负载。可扩展的系统调用接口允许用户应用程序和运行时管理系统之间的任意交互。RTM时序模型的彻底校准使管理开销得到合理的近似。我们的评估考虑了Agamid的精度、时间和设计空间探索能力。我们的发现证实了将运行时管理、硬件架构和用户应用程序的建模集成到单个事务级框架中的有效性。

期刊介绍： Embedded (electronic) systems have become the electronic engines of modern consumer and industrial devices, from automobiles to satellites, from washing machines to high-definition TVs, and from cellular phones to complete base stations. These embedded systems encompass a variety of hardware and software components which implement a wide range of functions including digital, analog and RF parts. Although embedded systems have been designed for decades, the systematic design of such systems with well defined methodologies, automation tools and technologies has gained attention primarily in the last decade. Advances in silicon technology and increasingly demanding applications have significantly expanded the scope and complexity of embedded systems. These systems are only now becoming possible due to advances in methodologies, tools, architectures and design techniques. Design Automation for Embedded Systems is a multidisciplinary journal which addresses the systematic design of embedded systems, focusing primarily on tools, methodologies and architectures for embedded systems, including HW/SW co-design, simulation and modeling approaches, synthesis techniques, architectures and design exploration, among others. Design Automation for Embedded Systems offers a forum for scientist and engineers to report on their latest works on algorithms, tools, architectures, case studies and real design examples related to embedded systems hardware and software. Design Automation for Embedded Systems is an innovative journal which distinguishes itself by welcoming high-quality papers on the methodology, tools, architectures and design of electronic embedded systems, leading to a true multidisciplinary system design journal.
