Active System Messages

Join the Pitzer OS upgrade Early User Program

OSC is upgrading Pitzer from RHEL7 to RHEL9, bringing updated tools and libraries. RHEL7 will no longer be available after the upgrade. Join the Early User Program (no application needed) to test your workflows between June 23 and July 27, 2025 (tentative). See this page for more information: https://www.osc.edu/resources/technical_support/supercomputers/pitzer/pitzer_os_upgrade_and_early_user_program

Remove data from OSC Scratch file system

The scratch file system (/fs/scratch) is very full. Please help reduce your scratch file system usage by deleting data that is no longer needed; compressing infrequently accessed data and identifying important data that needs be moved to OSC's other file system. OSC may perform emergency file deletion to maintain the overall health of the service, if needed.

Change is Coming!

Later this fall, OSC will be introducing a major change to the current process clients use to get help. We will be rolling out a new web-based system for clients to manage and review open cases with the service desk. More information will be forthcoming over the next few months, so keep an eye out for messages on various OSC communication channels, as well as at https://www.osc.edu/service_portal_deployment .
