System Downtime August 8 2023
A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, August 8, 2023. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, and HPC file servers. MyOSC and state-wide licenses will be available during the downtime. See this link for more details: https://www.osc.edu/calendar/events/2023_08_08-system_downtime_august_8_2023
Rolling reboot of all clusters starting from June 14 2023
Beginning 9am on Wednesday, June 14, we will be having rolling reboots of all clusters (Owens, Pitzer, and Ascend). This includes both login and compute nodes and will be done to perform OS updates. Login nodes will be rebooted at 9am on June 14, which will leave them unavailable for approximately 5-10 minutes. The rolling reboots won't affect any running batch jobs, but users may experience longer than usual wait times on all clusters.
Possible job failures due to MPI library change after May 20
There are changes on MPI libraries on Pitzer after May 20. We will upgrade MOFED from 4.9 to 5.6 and recompile all OpenMPI and Mvapich2 against the newer MOFED version. Users with their own MPI libraries may see job failures and will need to rebuild their applications linked against the MPI libraries.
Outage of most of 48-core Pitzer and a few Owens nodes May 20
Beginning Saturday, May 20, 2023, at 7 a.m., there will be an outage of most of 48core Pitzer and a few Owens nodes for UPS repair work. We anticipate this work to be completed at 2 p.m. on May 20.

Extended outage of 40core Pitzer nodes March 13, 2023
Beginning Monday, March 13, 2023, at 7 a.m., OSC will be taking the 40-core Pitzer nodes offline to replace the liquid cooling unit. We anticipate this work may take until Friday, March 17 to complete. We are working with our vendors to reduce the outage duration as much as possible.

OSC enables Globus High Assurance storage endpoint
A new High Assurance Globus endpoint for OSC will be deployed to manage protected data on February 2, 2023.
This will affect current projects at OSC which use Globus to manage their protected data. These projects will need to use the new High Assurance Globus endpoint to access their data. The name of the new endpoints are OSC /fs/ess High Assurance for project storage (/fs/ess) and OSC /fs/scratch High Assurance for scratch storage (/fs/scratch).
