OK, here we go. Blogging. First time for me as well. Anyway ...
I wanted to quickly list the most interesting things I found particular interesting today so that everyone can quickly look them up (on the indico page which can be found here: http://indico.cern.ch/conferenceOtherViews.py?view=standard&confId=82919):
- Tier-2 WAN networking was significantly improved by moving the Imperial College T2 outside the firewall. Who knew ... (http://indico.cern.ch/getFile.py/access?contribId=0&sessionId=0&resId=0&materialId=slides&confId=82919). But in general it is rather difficult to operate a university T2 because of the scattered infrastructure over the campus and of course the manpwer situation.
- A lot of discussion about the differences and different usage of GGUS and Savannah by the different communities. A good summary of the situation was that GGUS is a general ticketing system while Savannah is more used as a VO specific system
- Interesting fact from the Tier-1 presentation (http://indico.cern.ch/getFile.py/access?contribId=1&sessionId=0&resId=1&materialId=slides&confId=82919): Idle batch worker nodes use ~18tonnes CO2 /month (~£3K electricity). This is important as the usage of the Tier-1 sites by the LHC experiments is currently rather intermittend instead of flat. I think this has mostly to do with the amount of data we are currently procesing and the rush before the ICHEP conference.
- Ian gave a very good presentation about resource usage worth a read: http://indico.cern.ch/getFile.py/access?contribId=5&sessionId=0&resId=0&materialId=slides&confId=82919
The rest of the day was mostly spend with storage presentations and discussions and I leave that to James to comment :-)
Cheerio from London, Germany vs. Spain is starting in 1 hour, hopefully an interesting and exciting game.
