Compute server announcement
The majority of the GCE compute nodes have been rebuilt and are back online at this time. We have also added a few nodes with this work. Please see virtualhelpdesk.cels.anl.gov/docs/linux/login-compute-and-home-nodes/ for an updated list of current hostnames/configurations as some nodes have been renumbered.
As most of the nodes are now running ubuntu 20.04, if you find any needed modules missing please send a request and we will get those added asap.
Note: compute-03.cels.anl.gov and compute-04.cels.anl.gov are still down at this time as they are being moved to another location. We hope to have them back in service late this week or early next.

On Monday, Feb 14, 9:30am CST, we will be taking down the following GCE compute nodes: compute-03.cels.anl.gov, compute-04.cels.anl.gov, compute-05.cels.anl.gov and compute-06.cels.anl.gov for system upgrades. This upgrade will require about 4 hours of downtime. When they come back up, they will be running the most recent GCE compute/workstation build (Ubuntu 20.04). This will not affect data in your home or project directory, however no local data on the nodes will be retained. Please remember /scratch is ephemeral storage, can disappear at any time, and is not backed up. Please make sure you copy any data in that location to somewhere else prior to the downtime.
We’re actually reconfiguring hardware that’s been repurposed from Legacy, so some machines will be moving around. After this work is done, we’ll update virtualhelpdesk.cels.anl.gov/docs/linux/login-compute-and-home-nodes/ with the current configurations, and release compute-10.cels.anl.gov (big memory machine, formerly compute001.mcs.anl.gov) at that time.
