gem5 Boot Camp 2022
We are happy to announce the first gem5 Boot Camp, to be held at UC Davis from July 11th to July 15th 2022. The purpose of the gem5 Boot Camp is for junior computer architecture researchers, particularly PhD. students, to learn how to use gem5 in their projects. The Boot Camp, held over 5 days, will take attendees through setting up basic system simulations, creating bespoke components, learning to interpret gem5 stats, and up to running and modifying simulations comparable to real-world systems.
This event is free for all accepted attendees. There is no cost for registration. Accommodation and meals will be provided, and travel grants will be available.
Important Note: Registration for this event is now closed.
Livestream and discussion
You can find links to all of the livestreamed videos on YouTube.
Instead of using YouTube comments, we will be using Slack for our discussions.
You can use the following invite link to enter the slack.

Key Dates
- Boot camp: July 11th to July 15th 2022
Application deadline: May 18th 2022 (Apply here)
When and where is the Boot Camp?
The Boot Camp will be held from July 11th to July 15th 2022 at UC Davis in Davis, California. Attendees will attend workshop sessions each day, typically from 9AM to 5PM. Accommodation will be sponsored by NSF from July 10th to July 16th (6 nights).
What should attendees expect?
There will be 5 full days of workshop activities centered around learning gem5. The workshop will start with the assumption of no prior experience using gem5 and aims to go give attendees a solid and broad foundation of knowledge of gem5 in carrying out computer architecture research.
The workshop will give attendees the opportunity to:
- Learn how to create SimObjects.
- Learn how to use the gem5 Standard Library to create simulations.
- Get to grips with gem5art.
- Understand the gem5 statistics module and how to use it in your experiments.
- Create full system simulations capable of running real-world operating systems and software benchmarks.
- Network with others in the computer architecture research community.
And much, much more!
Breakfast, lunch, and dinner will be provided, as well as afternoon snacks. Attendees will be hosted on campus with evening social events planned.
Who can apply?
Anyone can apply though, as spaces are limited, preference will be given to early career researchers (e.g., first or second year PhD and masters students planning on applying for a PhD). We especially encourage those from non-research universities, minority serving institutions, and universities without PhD programs to apply.
How can I apply?
Registration for this event this event is now closed.
Those wishing to attend can fill out the following Google Form by May 18th: https://forms.gle/3wWPsMDfXyaChmQ68
If your application was successful you will be contacted, via the email address provided, by June 1st.
What does it cost?
This event is sponsored by the NSF. There will be no cost to attend. Accommodation on the UC Davis campus, meals, and social events will be provided as part of the event.
We will be offering travel grants which can be applied for to cover transport expenses after the event.
