all services are running EMI
now migrating worker nodes to EMI2 release (sl5)
for WLCG and other vo we have test queue with the emi2-sl6 worker nodes
recently upgraded/replaced part of the worker nodes
most of the recent purchases for the worker nodes are for the Interlagos AMD processors
we observe some discrepancy between the HEPSPEC results and the real jobs from the vo's for Intel and AMD processors (does anyone knows about the plan for new benchmark to replace HEPSPEC?)
added recently storage space to the SE's. This month there will be another update for storage
Since August we run cvmfs-nfs version for the atlas software directory. Works rather nice (cvmfs-nfs server is extremely old server, but with SSD) for our case. We had up to 4.500 running atlas jobs.
The only problem we observe is  when too many (more than 5-10) jobs do the setup of atlas software at the same time on the worker node (this doesn't influence jobs on other worker node,
so it's nfs-client issue)
