1. Report on Installed Resource Capacity Flavia Donno CERN/IT-GS WLCG Management Board, CERN 25 November 2008

2. Computing Capacity Glue attributes GlueSubClusterLogicalCPUs = Total number of core/hyperthreaded CPUs in the subcluster (including machines in state offline or down) GlueHostBenchMarkSI00 = Average SpecInt2000 rating per LogicalCPU CECapability: CPUScalingReferenceSI00= the CPU SI00 for which the published GlueCEMaxCPUTimes are valid. CECapability: Fairshare= : ; This value is used to express a specific VO share if VO shares are in operation.

Aggregation of heterogeneous computing resources managed by a batch system Set of (homogeneous) computing resources forming part of a Cluster It describes a batch queue

3. Storage Capacity WLCG Management Board, CERN 25 November 2008 3 Glue attributes GlueSACapability: Installed[Online|Nearline]Capacity = Online or Nearline space part of a Storage Area. It can be configured but not reserved or reserved but not yet part of a space token or reserved and assigned to a VO.

It describes storage resources at a site. It could represent one or more storage systems. It describes a logical view of a portion of space that can include disk and tape resources. It describes VO specific attributes of a Storage Area

4. Installed Capacity: status WLCG Management Board, CERN 25 November 2008 4 A document has been published with all details, operational instructions for site administrators and explicative examples https://twiki.cern.ch/twiki/pub/LCG/WLCGCommonComputingReadinessChallen ges/WLCG_GlueSchemaUsage-1.7.pdf The document is the result of many discussions within the group which includes representatives from: The OGF Glue Schema Working Group The EGEE Worker Nodes Working Group OSG Storage Information Provider Developers Storage Accounting representatives Client providers We are in the process of reviewing WLCG/EGEE documents and tools to evaluate consequences and needed work: GridMap, Gstat, SAM tests APEL/cesga accounting and NGS Storage Accounting GOCDB Administrators FAQs and documents Glue 2.0
