Between now and September 30, 2024, ALCF will be conducting its annual data call to gather information about our user community. We are seeking the participation of every project PI assigned an ALCF allocation and every ALCF user who is active in FY24 (October 1, 2023 - September 30, 2024). Some of the data we gather in our annual data call will be published by DOE’s Office of Science. You can find examples of past User Facility user statistics here: https://science.osti.gov/User-Facilities/User-Statistics. Other information is used to generate a current snapshot of ALCF activities and may also be publicized on the DOE website: https://www.energy.gov/science/office-science. Users will have the opportunity to respond to a forthcoming email about the data call.
