UWMadisonCMS Open Science Grid Site Policy Page

Processing Policies

• All access to US-CMS processing resources for other OSG VOs is provided on an opportunistic basis unless otherwise arranged.
• Additional non-US-CMS resources (GLOW, CHTC, and Computer Science Condor pool) are available for opportunistic use by all OSG VOs.
• When using opportunistic resources, immediate preemption of jobs may happen when there are higher priority jobs.
• US-CMS requests that VOs submit via Condor-G with the Grid Monitor enabled, because this reduces load on the CE.

Storage Policies

• CMS Will provide a GridFTP interface to AFS data directories in the legacy Grid3 mode.
• Access to an SRM SE is provided to all OSG VOs
• No tape backup is provided. Either RAID 5 or resilient dCAche will be used to store all files.
• Until resource reservations are available in SRM interface, under normal operating conditions CMS will remove all files older than 30 days
• If the file system fills, CMS will attempt to contact the largest users through the iGOC and provide 4 hours of warning before deleting files
