|The OpenOndemand portal for Vera cluster is now available at https://vera.c3se.chalmers.se. It provides a simple way to run interactive jobs on the cluster, such as jupyter notebooks, RStudio, VS code, and even a full desktop session. Anyone using
|The /cephyr storage will be moved to new hardware. From 09:00 July 11 both Vera and Alvis will be completely unavailable while we sync the files and make the transition. We don't expect this to take longer than a week. Jobs that request a walltime beyond this time will not start until the system is back up again.|
|Due to an unexpected cooling outage in Alvis's main server hall large parts of the system has been shut-down. The cooling outage will continue until Monday morning and we will try to get the system up as soon as we are able. All A40, A100 nodes, the CPU node, and the alvis2 login node will be offline. Any jobs that where running there had to be killed due to this emergency.|
|Chalmers e-Commons is still hiring.; system administrators and systems engineer.|
|Cooling system will be serviced. All A100 and A40 nods in Alvis will be shut down for the day. Jobs with walltimes beyond 07:00 won't start until service is done.|
|NAISS has replaced SNIC. Read more at NAISS website and SNIC newsletter.|
|All nodes (including private partitions) have been updated to Rocky 8. If you have, you should stop using the
|Almost all nodes have been updated to Rocky 8. There are much more updated nodes than are still running CentOS7.|
|Vera expansion is now live. All Vera users should read the news page for how to use the new nodes and the upcoming changes that will affect all nodes.|
