This event is being hosted by two of our Reproducibility Ambassadors — PhD students selected through our RepAmb (Reproducibility Ambassador) program to represent reproducibility initiatives at major systems conferences. The ambassador program sponsors active Chameleon and Trovi users to travel to conferences, share their work packaging reproducible experiments, and engage the broader research community around practical reproducibility. Our ambassadors for FAST '26 are Sabiha Afroz (Virginia Tech) and Hansen Idden (Virginia Tech). If you'd like to learn more about the ambassador program — including how to nominate a student from your group — please reach out to Marc Richardson or Rani Irawan.

The REPETO project (an initiative funded by the NSF FAIROS RCN to build a network for practical reproducibility in experimental computer science) invites FAST'26 attendees to join our BoF sessions on February 24th and February 25th, 2026, to learn about packaging storage research experiments on Chameleon. Chameleon is an open platform, which means that the hardware resources that folks use for their experiments will also be available to anybody who wishes to reproduce a presented experiment — all you will need is the packaging of the experiment itself!

We will teach the audience about tools and services Chameleon provides to share experiments, including the platform's integrated JupyterHub, Chameleon daypass, which allows you to give access to the testbed to anybody who wants to reproduce your experiment, and Chameleon Trovi, a sharing portal that allows you to share digital research and education artifacts, such as packaged experiments, workshop tutorials, or class materials.

During the sessions:

• The Chameleon team will present an overview of the testbed and highlight features that facilitate practical reproducibility in computer science research.
• Each session will include a panel discussion with FAST authors who used Chameleon to package their experiments for the conference.
• The audience will have the opportunity to try replicating the experiments that the FAST authors packaged on Chameleon hardware or try packaging their own experiments to share on Trovi.

Where/When?

We will host two in-person sessions (one hour each) at FAST'26 on Feb. 24 (7:00 pm–10:00 pm) and Feb. 25 (5:30 pm–8:30 pm), 2026. Details about the BoF sessions will be available at the conference. Our agenda will include:

• 15 min Chameleon presentation (by Chameleon staff)
• 30 min presentation from the Chameleon Reproducibility Ambassadors
• 15 min Q&A session

About the Reproducibility Ambassador Program

The students hosting these sessions — Sabiha Afroz and Hansen Idden from Virginia Tech — were selected through the Chameleon Reproducibility Ambassador (RepAmb) program, a travel grant initiative that sponsors PhD students to attend major systems conferences and advocate for research reproducibility.

To earn their ambassador status, each student packaged experiments from published FAST papers on Chameleon Trovi, making those experiments publicly reproducible by anyone with a Chameleon account. This kind of hands-on engagement is central to what the program is all about: not just talking about reproducibility, but demonstrating it live.

If you're a faculty member with a PhD student who is an active Chameleon user and would be a great ambassador at an upcoming systems conference, we'd love to hear from you. The program covers up to $1,000 in conference registration and travel costs, and is open to students at US universities attending ACM, USENIX, or IEEE conferences through September 2026. Reach out to Marc Richardson or Rani Irawan to learn more.
