8. efi.uchicago.edu ci.uchicago.edu 8 Failover Statistics – last two weeks

9. efi.uchicago.edu ci.uchicago.edu 9 Testing & Development New dCache redirector plugin developed – Provides simpler federating, improves efficiency and stability of dCache endpoints. 100Gbps tests as soon as MWT2-BNL circuit available Testing overflow now the new test pilot is available Working with EOS on finding solution to a too many DDM endpoints issue Wei continuously testing using input files from analysis jobs. Restarting frameworks measuring and following IO characteristics of ATLAS data formats – in particular xAOD.
