Parsl & funcX Fest 2021 - The Parsl/funcX Community Meeting

We are hosting the Parsl & funcXFest Community Meeting as a virtual meeting in two half-day sessions on October 27 (9am-1pm CDT) and October 28 (1pm-5pm CDT), 2021.

The meeting will bring together researchers, developers, and cyberinfrastructure experts from around the country to discuss experiences using Parsl and funcX.

Building on two prior ParslFest meetings, we are combining with the funcX community to launch a larger joint community meeting. funcX is a federated function as a service platform that builds on Parsl (enabling simple remote invocation).

Registration (free): Please indicate if you are interested in presenting a lightning talk.
