System Downtime December 19 2023
A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, December 19, 2023. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, HPC file servers, and state-wide licenses. MyOSC (the client portal) will be available during the downtime. In preparation for the downtime, the batch scheduler will not start jobs that cannot be completed before 7 a.m., December 19. Jobs that are not started on clusters will be held until after the downtime and then started once the system is returned to production status.
Nodejs
Nodejs is used to create server-side web applications, and it is perfect for data-intensive applications since it uses an asynchronous, event-driven model
Running jobs requeued on all clusters
The Slurm upgrades during rolling reboots of Ascend, Owens and Pitzer we performed today (Oct 25 2023) cause all running jobs on the systems requeued around 8:45am. You will not be billed for the consumed resources before the jobs were requeued.
