WLCG Resources Reporting Laurence Field 2

WLCG Resource Reporting • Not the same as grid or cloud accounting! • • WLCG is supported by Mo. Us • • And the level of that commitment Ensure sufficient resources are in place • • Mo. Us represent a commitment to support WLCG Pledges are a renewal of that commitment • • But they both have a role to play Report on how those resources were used Cloud usage must therefore also be reported • Can not be considered production otherwise 3

WLCG Resource Reporting Task Force • Mission • Ensure cloud resource can be reported • • Objectives • Gap analysis of current situation • Define a plan with a list of actions • • And hence be counted towards pledges Follow up on the action list Outputs • Analysis and proposal document • https: //twiki. cern. ch/twiki/pub/ITSDC/WLCGResource. Reporting-v 1. docx Twiki page • • https: //twiki. cern. ch/twiki/bin/view/ITSDC/WLCGResource. Reporting Action List • • Follow-up 4

Proposal • Build upon the existing APEL cloud accounting work Publisher extracts the required information from the cloud resource • • Should be cross-checked with information from the VO OSG resources can send accounting summaries from Gratia • • Automated monitoring verifies that records are being published EGI Accounting Portal provides an aggregated summary • • Sends the result to the accounting database Includes a HEP-SPEC-06 normalization factor Should be registered as eu. egi. cloud. accounting in the GOCDB Similar to how this is done for Grid resources So far Nordu. Grid resources are publishing directly using SSM Extend REBUS to include cloud accounting values 5
