Owens
System Downtime March 14, 2023
A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, March 14, 2023. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, and HPC file servers. MyOSC (https://my.osc.edu) and state-wide licenses 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., March 14, 2023.
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).
Changes on MPI libraries after Dec. 13, 2022 downtime
During the Dec. 13, 2022 downtime, we will upgrade MOFED from 4.9 to 5.6 and recompile all OpenMPI and MVAPICH2 against the newer MOFED version on Owens.
After downtime, users with their own MPI libraries on Owens may see job failures and will need to rebuild their applications linked against the MPI libraries.
System Downtime December 13, 2022
