• SFU-LCG2 (CA cloud) joined– Direct dCache – Connected to xrd-
central• Mayor T1s missing
– CA –TRIUMF – good progress
– ES – pic – working with them
– FR – Lyon – progress stalled
– NL – Sara, Nikhef – no progress

North American Redirectors
• Restructuring of the redirection tree in North America• Hosted at BNL; FAX operations team provides configuration
and operational support– atlas-xrd-us.usatlas.org
o North American region– atlas-xrd-east.usatlas.org
o -BNL, BU, Victoria, Scinet– atlas-xrd-central.usatlas.org
o MWT2, AGLT2, OU, SWT2– atlas-xrd-west.usatlas.org
o SLAC, TRIUMF, McGill, SFU
• Status and timeframe:– Hosts and configurations ready. Waiting for git repository’s
connection.

saturation occurrence at FZK-LCG2
• ALICE analysis is suspect
• If it needs an analysis to find who/what is responsible, then the monitoring is inadequate.

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.
