WLCG Global Information Registry

Introduction

The WLCG Global Information Registry prototype brings together information published by different grid infrastructures like EGI and OSG. It shows both information on pledged resources and actual available resources. The WLCG Global Information Registry aims at aiding LHC experiments to configure their own experiment databases for job submission and storage management by providing a single entry point for information on WLCG resources.

Hotfixes

Please, find the list of hotfixes agreed by all LHC VOs that will be implemented in the Global Information Registry until they are eventually fixed in the corresponding information sources.

Comparator

Please, find the comparison results between the Global Information Registry and AGIS.

Requirements

Job Submission

ATLAS

The following attributes should be provided to enable populating the ATLAS AGIS database used to submit jobs.

AGIS GLUE 1.3 GLUE 2.0
ce_endpoint GlueCEHostName GLUE2EndpointURL
ce_flavour GlueCEImplementationName GLUE2EndpointInterfaceName
ce_jobmanager GlueCEJobManager GLUE2ManagerProductName
ce_queue_maxcputime GlueCEMaxCPUTime GLUE2ShareMaxCPUTime
ce_queue_maxwctime GlueCEMaxWallClockTime GLUE2ShareMaxWallTime
ce_queue_name Glue CEName GLUE2ShareMappingQueue
ce_queue_status GlueCEStatus GLUE2ShareServingSate
ce_version GlueCEImplementationVersion GLUE2EndpointImplemenationVersion
rc N/A (Rebus Federation) N/A (Rebus Federation)
rc_site GlueSiteUniqueID GLUE2ServiceAdmindomainForeignKey

In order to provide the previous information, the following attributes are also needed. Note that in GLUE 1.3 the foreign key relationships are more complicated:

GLUE 1.3 GLUE 2.0
GlueServiceUniqueID, GlueForeignKey: GlueSiteUniqueID GLUE2ServiceUniqueID, GLUE2ServiceAdmindomainForeignKey
In GLUE 1.3 there is a constraint that one service can only contain one endpoint GLUE2EndpointUniqueID, GLUE2EndpointServiceForeignKey
GlueServiceUniqueID GlueVOViewLocalID (not globally unique), GlueCEUniqueID= (from the CE GlueForeignKey: GlueClusterUniqueID ) GLUE2ComputingShareUniqueID, GLUE2ComputingShareServiceForeignKey
GlueCEUniqueID, GlueForeignKey: GlueClusterUniqueID GLUE2ComputingManagerUniqueID, GLUE2ComputingManagerServiceForeignKey

LHCb

  • GOCDB downtimes associated to the computing resources have been requested by LHCb and added to the registry.

Storage Management

ATLAS
