项目摘要

Computer systems are increasingly important to society and the advancement of science. In recent years, technological trends have made it increasingly difficult to continue scaling their performance. As a result, research to further improve computer systems is vital. Traditionally, this research has relied on cycle-level software simulation of these computer systems to model the potential improvements of novel techniques. However, much of the software was written 15 years ago, and it is currently maintained by students and researchers. This project will make a concerted effort to improve the underlying simulation infrastructure, which will enable increased research output by the computer systems community. It will specifically focus on the gem5 infrastructure, which is widely used in the community (e.g., cited over 3000 times) and considered the de facto tool for simulating all components of the computing system.This project will enhance and rejuvenate the aging gem5 community infrastructure through improvements to the underlying gem5 components, community outreach and improved user's services, and developing new models for emerging devices required for evaluating important applications (e.g., machine learning, augmented and virtual reality, high performance computing, and system security). These improvements will increase the research output of gem5's broad user base and extend the ability to perform hardware-software co-design to the entire computer systems community. This project will broaden the already vibrant gem5 community through reducing the barrier to entry by (1) running two gem5 summer schools to introduce junior graduate students to gem5 and computer systems research, (2) simplifying gem5's interface, (3) improving the community's documentation and communication channels, and (4) supervising a community code shepherd to help researchers integrate their code with the community infrastructure. The investigators will also create a set of 'known-good' system configurations that will significantly increase the productivity of researchers performing detailed cycle-level research studies. These system configurations will be proxies for current state-of-the-art systems and will be publicly validated against real systems and workloads suggested by the community.This project will create a sustainable path for the future of the gem5 infrastructure by improving the code testing coverage and increasing the robustness of hardware device models. Additionally, community outreach efforts will broaden the community increasing the impact of gem5 and providing more contributors to continue development of this infrastructure after this project completes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

计算机系统对社会和科学的发展越来越重要。近年来，技术趋势使得继续扩展其性能变得越来越困难。结果，进一步改善计算机系统的研究至关重要。传统上，这项研究依赖于这些计算机系统的周期级软件模拟，以模拟新技术的潜在改进。但是，大部分软件是15年前撰写的，目前由学生和研究人员维护。该项目将齐心协力改善基础模拟基础架构，这将使计算机系统社区的研究输出增加。它将特别专注于GEM5基础架构，该基础架构在社区中广泛使用（例如，引用了3000次），并考虑了事实上的工具，用于模拟计算系统的所有组件。该项目将增强并使衰老GEM5社区基础设施通过对社区的启发，并改善社区的服务，并改善衰老的GEM5社区基础设施，并改善了社区的发展，并改善了ERSUNEDERSER，并改善了ERSEREDER EXTER，并改善了ERSUNEDERIDER，并改善了ERSUNE的ERSERING ERSER，并将其改善重要的应用程序（例如，机器学习，增强和虚拟现实，高性能计算和系统安全性）。这些改进将增加GEM5广泛用户群的研究输出，并扩展对整个计算机系统社区执行硬件软件共同设计的能力。该项目将通过（1）通过（1）运营两所GEM5暑期学校进入进入的障碍来扩大已经充满活力的GEM5社区，以将初级研究生介绍到GEM5和计算机系统研究中，（2）简化GEM5的界面，（3）改善社区的文档和沟通渠道，以及（4）（4）社区代码与社区相结合的社区代码，以帮助他们组成社区的代码。研究人员还将创建一组“已知良好”的系统配置，这些系统将显着提高进行详细的循环级别研究的研究人员的生产率。这些系统配置将是当前最新系统的代理，并将针对社区建议的实际系统和工作负载进行公开验证。该项目将通过改善代码测试覆盖范围并提高硬件设备模型的鲁棒性来为GEM5基础架构的未来创造可持续发展的道路。此外，在该项目完成后，社区推广工作将扩大社区的范围，从而增加了GEM5的影响，并为更多的贡献者提供了继续发展该基础设施的贡献者。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来获得支持的。
