The Longwood High-Performance Compute Cluster and LASER at Massachusetts Green High-Performance Computing Center (MGHPCC) will be offline from Monday, June 2, 2025, at 9:00 AM through Friday, June 6, 2025, at 5:00 PM EDT (UTC-4) for annual facility maintenance.

All systems in the MGHPCC facility must be powered down during this time.
