The Grand filesystem will be undergoing upgrades between April 18 and April 20, 2022, and it will be unavailable during this time. To make sure your submitted jobs are not impacted, please follow the guidance on specifying filesystem(s) at https://www.alcf.anl.gov/support-center/theta/running-jobs-and-submission-scripts#qsub_filesystems. If you do not specify any filesystem, then the job will be tagged as requesting all filesystems (including Grand) and may be put on hold unnecessarily. Please contact support@alcf.anl.gov with any questions or concerns.
