OSG VO Policy
Processing Policies
- All access to US-CMS processing resources for other OSG VOs is provided on an opportunistic basis unless otherwise arranged
- Non-CMS VOs have a hard limit of 48 hours of wall clock time
- If US-CMS operators are forced to kill running processes, we will attempt to contact the iGOC to provide warning to the affected VO.
- Under normal running conditions we will attempt to give four hours notice
- During some running conditions we may be forced to remove processes without warning
- US-CMS requests that VOs submit using Condor Grid Monitor. VOs unable to submit through grid monitor will be limited in the number of active processes allowed.
Storage Policies
- CMS will provide the four canonical storage areas: $APP, $DATA, $TMP, $WN_TMP.
- $APP is an area for software installation shared across all worker nodes. It is read/write from the head node via the jobmanager-fork queue, and read-only from worker nodes. By default, the directory is mode 1777. Quotas are set to 1 GB per account if it is a pool account and 10 GB otherwise. No purge policy has yet been set. Additionally, $APP/maintained is a read-only directory with writes enabled only for users who are official VO software distributors (and have the appropriate role in VOMS). New VOs should put in a request via their local support center to give their software distribution role the appropriate permission. No quotas are set. Files will not be purged by age. If the filesystem fills, CMS will attempt to contact the users consuming the most space through OSG Operations.
- $TMP and $DATA point to the same area. It is a read/write area for temporary files shared across all worker nodes. By default, the directory is mode 1777. Quotas are set to 2 GB per account if it is a pool account and 20 GB otherwise. No purge policy has yet been set.
- $WN_TMP is a read/write area for temporary files local to each worker node. No purge policy has yet been set.
