announcing and logging changes

This policy defines a time schedule for announcing and logging changes to all scheduled systems, networks, important application software, and system-defined support software across the participating centers. Change announcements that apply to the default, floor version, or system accessible to the users are summarized in the table below.

Category Description Time Frame
Major Any upgrade/change to an allocated HPC machine that may affect multiple software packages. 1 month
Minor Any upgrade/change to an allocated HPC machine or center's infrastructure that may hinder the effective use of resources at the center. 2 weeks
Emergency/Security Any upgrade/change requiring Immediate action. As early as possible

All centers should use the CCAC News And Maintenance Tool (NAMT) to submit their announcements. All change announcements will remain on the CCAC Web site for a period of one year. After this time, announcements will be archived in the HPCMP's Storage Lifecycle Management system until they are no longer required by the Program.
