The gem5 simulator is an open source computer architecture simulator used in academia and in industry. gem5 has been under development for at least 15 years initially at the University of Michigan as the m5 project and at the University of Wisconsin as the GEMS project. Since the merger of m5 and GEMS in 2011, gem5 has been cited by over 4800 publications. gem5 is also used by many industrial research labs including ARM Research, AMD Research, Google, Micron, Metempsy, HP, Samsung, and others. The canonical citation for gem5 is now the gem5-20 paper
Professor Jason Lowe-Power is a the chair of gem5’s project management committee and a contributor to gem5. gem5 is heavily used by the DArchR lab to investigate heterogeneous memory, security, and other projects.
The DArchR group is leading the RE-gem5 project. RE-gem5 is a directed effort to rejuvenate the underlying infrastructure of gem5. RE-gem5 is not a new simulator or a new project; it is a project to enhance and support the current gem5 infrastructure. We are embarking on the RE-gem5 project to reinvigorate the gem5 infrastructure to enable the next 15 years of computer architecture research. This project will enhance and rejuvenate the aging gem5 community infrastructure through improvements to the underlying gem5 components, community outreach and improved user services, and developing new models for emerging devices required for evaluating important applications. 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.
