Occasionally users may want to automate a common recurring task. Typical use cases are to initiate batch jobs, transfer input data from an external site, or run some automated testing. The UNIX cron service allows users to schedule scripts to be run based on a recurrence rule. As of December 2023 we have deployed a high-availability cron service independent of the individual HPC systems to support these workflows. This separated, HA solution allows us to perform maintenance on the HPC resources while not interrupting cron workflows that can tolerate the downtime. This new cron system is the ideal replacement for users looking to rehost previous cron workflows from Cheyenne.
