Parsl & funcX Fest 2022 - The Parsl/funcX Community Meeting (Sep 13-14)

The fourth Parsl & funcXFest Community Meeting will be held as a hybrid meeting on September 13-14, 2022. Thein-person component will be held at the University of Chicago.

The meeting brings together researchers, developers, and cyberinfrastructure experts from around the world to discuss experiences using and developing Parsl and funcX. funcX is a federated function as a service platform built upon Parsl.

Registration is free and we would love for you to present a lighning talk describing your work with Parsl or funcX

We have funding available to support travel to the workshop. Please contact Kyle Chard ( for information.
