FYI, US ATLAS suspects that most of these usage numbers are over estimated by a large margin (because we don't have the resource to delivery so much). I spent last week investigating this discrepancy. It has something to do with SpecInt2K to HS06 conversion (one should measured HS06, not converting from SI2K by 4x factor). As a result, SLAC's #s were over estimated by ~30% for the last five months. We are requesting OSG to use measure HS06 in the future. regards, Wei Yang | [log in to unmask]<mailto:[log in to unmask]> | 650-926-3338(O) Begin forwarded message: From: Lcg Office <[log in to unmask]<mailto:[log in to unmask]>> Date: March 9, 2011 1:50:17 PM PST To: "worldwide-lcg-management-board (LCG Management Board)" <[log in to unmask]<mailto:[log in to unmask]>>, "project-wlcg-tier2 (List of LCG Tier 2 sites)" <[log in to unmask]<mailto:[log in to unmask]>> Cc: Lcg Office <[log in to unmask]<mailto:[log in to unmask]>> Subject: Tier 2 accounting - February 2011 Dear all, Please find below the Tier 2 accounting report for February 2011: https://lcg.web.cern.ch/LCG/accounting/Tier-2/2011/february-11/Tier2_Accounting_Report_February2011.pdf Please send any comments to [log in to unmask]<mailto:[log in to unmask]> by Monday 14 March.
