ISCA 2023: gem5 Workshop


Note: This page is kept for archival purposes.

We are happy to announce the gem5 Workshop, to be co-located with ISCA 2023, in Orlando, Florida.

The gem5 Workshop is be an opportunity for members of the gem5 community to give presentations on their contributions to gem5 and gem5-related research. This year’s workshop will start with a 25 minute keynote by Dr. Bobby R. Bruce, titled “gem5 v22, v23 and the future”, and will continue with presentations and discussion panels on gem5 topics.

Call for Presentations

Note: The deadline for submitting presentations has passed. This call is kept here for archival purposes.

The gem5 simulator is an open-source platform that enables the modeling and simulation of computer systems at different levels of abstraction, including processor, memory hierarchy, and interconnects. It is widely used in academia and industry for research, education, and design space exploration. Now on its 5th iteration, the gem5 Workshop gives community stakeholders a chance to present their contributions and ideas, as well as engage in discussion with the wider community.

In this call we are soliciting presentation proposals from researchers, developers, and practitioners who are using or developing the gem5 simulator. The workshop will be co-located with ISCA ‘23 (June 17th to 21st, in Orlando, Florida), to be held on June 17th as an all-day event. The goal of the workshop is to give community members an opportunity to share their gem5-related research and insights, exchange ideas, and collaborate on future gem5 development goals.

This year we want to give anyone who wishes to an opportunity to present gem5-related topics at the workshop. As such we are foregoing Program Committee evaluation and will allocate presentation time on what we believe will invoke the most discussion. In short, as long as a presentation proposal is covering a gem5-related topic, we will allocate a time for it at the workshop. Ideas and contributions, big or small, are welcome.

Examples of gem5 topics which could be presented include, but are not limited to:

To submit a proposal, please send an email to Bobby R. Bruce at bbruce@ucdavis.edu with the following:

Above all else, we will welcome any presentation if it can be justified as being of interest to those who use and develop gem5.

To reward those who have helped improve the project, this year we we will be presenting gem5 Community Impact Awards during this year’s workshop. These awards will be presented to individuals, or groups, who have made significant positive contributions to the gem5 community. This includes introducing new features, improving the underlying infrastructure, supporting users, and any other contributions which have had substantial impact. The award will be given for work carried out within a loosely-defined 3-year sliding window meaning that contributions made between 2021 and 2023 will be acknowledged this year. Nominations for the award can be submitted via email to Bobby R. Bruce at bbruce@ucdavis.edu (self-nominations will be accepted).

Key Dates:

We look forward to receiving your proposals and seeing you at the gem5 Workshop!

Room and Venue

The workshop will be held in the Canary 1 room of the Marriott World Center Orlando.

Panel Session

The workshop will feature a panel session titled “The Future of gem5” to be held from 11:20 to 12:30. The five panelists, listed in the subsection below, will answer questions posed by the audience, and chairs (Jason Lowe-Power and Bobby R. Bruce), on the future of gem5.

The framing of this panel session will be the progress of gem5 since Jason’s ISCA presentation in 2015, “gem5 Horrors and What We Can Do About It”, a write-up of which is available at: http://www.lowepower.com/jason/gem5-horrors-and-what-we-can-do-about-it.html.

To start discussions Jason Lowe-Power will remind the panelists and audience of issues highlighted in this his 2015 presentation and the progress made on them. We will then open the floor to panel and audience to discuss issues that be tackled over the next half-decade of gem5 development. We wish to find out what are the horrors of gem5 today, and what can we do about them?.

We strongly encourage those interested in gem5 and it’s future development to attend this session and participate in the discussion.

Panelists

Poster Session

The workshop will feature a poster session to start at 14:55. This session will begin with a series of lightening talks by our accepted posters (3 minutes each, 1 slide) prior to a traditional poster session held in the same room.

The posters session is immediately before the 15:30 coffee break and may continue into the break if there is sufficient interest.

Those with posters may hang their poster at the start of the workshop (from 9:00) for viewing during the coffee breaks and lunch.
