Update - From October 2026 to December 2026, CURC will be implementing rolling updates on Alpine’s CPU nodes in the acpu and amem partitions. The nodes in these partitions will be updated in small batches, which is intended to minimize disruption to normal operations, but may lead to temporary increases in queue wait times.
