Dear bfys friends,

On Monday 22nd and Tuesday 23rd March, Nikhef and SARA jointly organise a Tier-1 workshop at Nikhef. This workshop is very useful for those of you planning to analyse the incoming data and discuss with GRID and LHCb computing people. The agenda of the meeting can be found below in the message of Nick Brook and on Indico: http://indico.cern.ch/conferenceDisplay.py?confId=84713 If you plan to join the meeting and/or dinner please register on the registration link on the indico page as it helps the organisers with catering etc.

Cheers, - Marcel

Dear All

We would like to hold a "Tier-1 Jamboree" and we plan to synchronise this with the GDB meeting in March in Amsterdam. The plan would be to start the meeting on Monday 22nd March at 14:00 and end lunchtime on Tuesday 23rd. NIKHEF are happy to host the meeting. A very draft agenda is attached below. The purpose of this email is to check your availability. Of course if you feel you have burning issues you wish to  add to the agenda let me know. Jeff Templon at NIKHEF is looking for a swift answer on the number of participants so he can organise things on his side, so if you can let me know if you're interested asap that would be most appreciated,

Many thanks, Nick
