The Darshan team is pleased to announce the public availability of the ALCF Polaris Darshan Log Repository<https://urldefense.us/v3/__https://doi.org/10.5281/zenodo.15052603__;!!G_uC… >. This is an anonymized, continuously updated collection of all production logs captured on the 560 node Polaris system<https://www.alcf.anl.gov/polaris > at the ALCF<https://www.alcf.anl.gov/ >. We hope that continuous publication of this data helps the computer science community to better understand current production workloads.
As of this writing (June 5, 2025) the repository contains over 1.2 million log files and is growing at an average rate of roughly 3,000 logs per day, though coverage rates and job workloads vary considerably from day to day.
See the Zenodo report<https://urldefense.us/v3/__https://doi.org/10.5281/zenodo.15052603__;!!G_uC… > for more information about how to download, analyze, and acknowledge use of the data in publications.
See the CUG 2025 presentation<https://www.mcs.anl.gov/research/projects/darshan/wp-content/uploads/sites/… > (corresponding paper pending proceedings publication) for more information about how the repository was created, examples of analyses that can be performed on it, and links to tools that can be used to reproduce those examples.
