Durham 

Mike: Making good progress SL6. Ewan on monitoring, prototyped now, can be rolled out without much hassle. 
Ticked Biomed and had no response for a week. Have closed ticket as unsolved with threat of withdrawn support, will see if they reopen it. 

Aircon failure on Friday. Had to dump WNs to reduce air temp increase. 
Turned on on Monday.

EMI3 UI up and running. 

LHCb ticket 92590: Mark looked at update, and Vladimir suggested making a LHCb pilot mapping. Mike believes this has already been done. 
Some discussion about the mapping (syslog shows that *some* LHCb DNs are definitely being mapped to users). The issue is diagnosed as a missing pilot role mapping for LHCb.
Gareth shared Glasgow config to help Durham add the right mappings.

Edinburgh

Andy: Nothing much to report. Looking at SL6 move still, got SL6 CE accepting jobs, one of the test queues is now an SL6 test queue. Seems to work, but with a few errors (which seem to be related to the WN tarball). Unfortunately, the SL6 tarball is only in test - installed yesterday, and needs a few tweaks. Should be going soon.

Still battling over internal network restrictions, but ongoing.

Squid monitoring change - needed to get the site firewall adjusted, so needs a ticket to progress internally.

Ticket against ECDF, Wahid aware and will resolve.

-
Glasgow 

Mark: little happened here. Aircon unit once again rebuilt to prevent it dying whenever it is even slightly hot. 
Mark featured in an article in TechWorld on Extreme networking. 
Stuart is leaving in the next several months, we'll be replacing him via a hiring process. Date probably late July. 

Trying to put together a grant submission with GEANT. 

Pile production: even though we're not enabled for high memory jobs, PaNDA still assigned a few hundred 4G jobs to us (which then spun in PanDA without being able to actually be picked up by the pilots) 

Dave: has been developing more Graphite monitoring. Will be giving a talk at HepSysMan on this. 
New MICE user - MICE don't have a fully developed experiment software policy, so we've been making his software work locally at Glasgow.
