Out of Office: Holiday Break

The ARCH team will be out of the office next week for the holiday. During this period, tickets may take longer to respond to than usual. We appreciate your patience and understanding.

Upcoming Rockfish Network Outage

Rockfish will experience brief network outages between 6:00 AM to 9:00 AM on Saturday, December 23rd. Expect network downtime lasting 15-20 minutes multiple times within that timeframe during upgrades. During these interruptions, there will be no connections to login nodes. All enterprise networks will be impacted but no internal networks. This should not impact a running job unless that job requires internet access. 

Globus Connectors

Starting on January 2nd, 2024 JHU’s Globus subscription will add two connectors to Cloud providers: AWS and OneDrive. To connect to your OneDrive account, connect to Globus as described here, then search for collection “ARCH OneDrive”. You will need to authenticate to your “” and then you will have a list of your files and folders under the JHU OneDrive. Instructions for AWS will be available soon.

Rockfish Cluster Queue Configuration

As of January 9th, 2024, partitions and cues will be reconfigured to allow more effective utilization of resources. We have made a video that describes the new configuration for the Rockfish cluster. View here
