Office Hours for January 8, 2026 is cancelled. Maintenance shutdown continues…

We wanted to give you an update on where we are at with the data migration and the on-going maintenance service outage. We have escalated a request to the storage system vendor as well as the Science Engagement team at the Energy Sciences Network (ESNet – part of the DoE Labs). One of our main goals is keeping your data safe, so rest assured – no data will be lost during this manuever. That said, it’s always good practice to make a backup of any critical data, such as run results, outside of Hummingbird.

One lesson learned here is that size matters. This is where we ask for your help in the future. Please stick to our quotas (1TB per user in /home), curate your data (i.e. download only what you need and keep only the essential), share data where possible (via groups), and refrain from using HB’s storage system as long-term storage. When you’re done with data, please clean up after yourselves.

We are cancelling today’s office hours, and the team will continue to work towards getting the system back online.

Hello Hummingbird User Community,

We currently are planning to restore the cluster to normal (but improved) operations NLT January 15, 2026. Please continue to monitor this website for updates.

The Hummingbird Cluster is currently down for maintenance while we move to a new storage system.  We need to transfer nearly 750TB and until all data transfers are complete, we are unable to resume cluster operations. This migration is an essential part upgrading our computational capabilities with a new multi-PB storage service for our cluster, which will provide not only more storage, but also much faster file input/output once it is online.

These improvements are part of a $1.7M campus investment in shared HPC.Given the large inconsistency of the transfer speeds we are observing, we are unable to provide a concrete estimate for when we will be able to resume service. Our goal is January 15, 2025, but due to on-going technical issues, this may change.

We are doing everything we can to speed this process along as much as possible and will provide further information as we are able.
