Announcing VLDB 2026 Bird-of-Feather (BoF) Session on Reproducibility

The REPETO project (an initiative funded by the NSF FAIROS RCN to build a network for practical reproducibility in experimental computer science) invites VLDB'26 attendees to join our BoF sessions on September 3, 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.
• The session will include a panel discussion with VLDB authors who used Chameleon to package their experiments for the conference.
• The audience will have the opportunity to try replicating the experiments that the VLDB authors packaged on Chameleon hardware or try packaging their own experiments to share on Trovi.

Where/When?

We will host an in-person session (1.5 hours) at VLDB'26 on September 3, 2026 (15:45 - 17:15) at the STONE room. Details about the BoF sessions are available on the conference program. Our agenda will include:

• 30 min Chameleon presentation
• 20-25 min author demo
• 20-25 min Q/A session
