Pitzer

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).

Reduced Pitzer capacity starting Dec. 12, 2022

Beginning Monday, December 12, 2022, 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, December 16 to complete. Given uncertainties about the time necessary to complete this work, OSC engineers opted to begin this work before the December 13 downtime to increase the likelihood of the nodes returning online before the following weekend and to minimize the total outage. We are working with our vendors to reduce the outage duration as much as possible.

NVHPC

NVHPC, or NVIDIA HPC SDK, C, C++, and Fortran compilers support GPU acceleration of HPC modeling and simulation applications with standard C++ and Fortran, OpenACC® directives, and CUDA®. GPU-accelerated math libraries maximize performance on common HPC algorithms, and optimized communications libraries enable standards-based multi-GPU and scalable systems programming. Performance profiling and debugging tools simplify porting and optimization of HPC applications, and containerization tools enable easy deployment on-premises or in the cloud.

System Downtime December 13, 2022

A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, December 13, 2022. 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., December 13, 2022. 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.
