No system downtimes for week of December 4 - 8

December 1, 2023

None planned for Cheyenne, Casper, Derecho, GLADE, Quasar, Stratus, or JupyterHub.

As Cheyenne limps to the finish line, move to Derecho now!

November 29, 2023

Cheyenne suffered a cooling distribution unit (CDU) failure over the Thanksgiving holiday, causing two racks of compute nodes to go down until repairs can be completed. Service is underway but the venerable machine is in a degraded state with less than a month until decommissioning. Until repairs are completed, network performance is expected to be somewhat degraded particularly for large node-...

Cheyenne Countdown: New year, new you, new supercomputer! Switch to Derecho.

November 27, 2023

Now is a great time to switch to Derecho. Just in time for the New Year, Cheyenne will retire on December 31, 2023, to be replaced by the new supercomputer Derecho. The good news is that Derecho is 3.5 times more powerful than Cheyenne. However, the bad news is that researchers now only have a couple weeks left to wrap up all their computing projects on Cheyenne. It is officially the last m...

Cheyenne Countdown: Time to say your final farewells to Cheyenne.

November 27, 2023

Cheyenne users now have less than a month to say goodbye to Cheyenne. Cheyenne will be retired on the last day of the year: December 31, 2023. This means that all users must wrap up their projects on Cheyenne by that time. That means it’s a great time to transition your computing projects to Derecho. Even more importantly, if Cheyenne experiences a crash or power loss from this point forward...
