2. LHC Computing in NL SARA / NIKHEF : Tier-1 for ALICE, ATLAS, LHCb
SARA: bulk of resources, all of long-term mass store
NIKHEF: significant resources, bridge to experiments & middleware groups
Contribution to exp’ts scale roughly as our presence: 4 : 2 : 1 LHCb : ATLAS : ALICE
Fraction of world Tier-1 resources in Amsterdam: 23% : 11.5% : 5.75%
Tier-1 forms large part of National e-Science Center
n.b. LHC middleware must be generic enough for others!
NIKHEF : gridified analysis facility with rough scale of Tier-2

3. numbers 3 kSI2k == latest dual-CPU machine
NIKHEF today kSI2k, 10 TB disk
3 kSI2k == latest dual-CPU machine

4. External (personnel) funds now from EGEE and VL-E projects
How We Got Here
D0 Distributed Computing (since 2000)
first farm at NIKHEF
NIKHEF led 1st HEP reco on Grid
One of principal project partners
Third site to join EDG grid
Remained one of the five ‘core sites’ throughout the project
Contributions in this project earned us a fantastic position in the grid world
Bring LHC and “rest of world” closer together
Active participation builds consensus and makes an e-Science center with LHC Tier-1 a real possibility
External (personnel) funds now from EGEE and VL-E projects

5. Local Highlights Positioned well in LCG & EGEE
Enthusiastically accepted as Tier-1
One of ‘best run’ sites
One of first sites (#3 in EDG, compare #4 in WWW)
Membership on:
Middleware Design Team (US collaboration here too)
Middleware Security Group
Various other working groups and RTAGs
D. Groep chairs world-recognized EUGridPMA and IGTF
K. Bos chairs LHC Grid Deployment Board
Profit from close collaboration with best network in world (Surfnet) and experts to exploit it (UvA)

6. people PDP group (grid)
10 staff (5 permanent), 9,5 FTE
Three arms: operations / applications / security
CT group (everything else; ~ 70% PDP also in CT)
21 staff (16 permanent)
15% support / management
35% system & hardware administration
50% technical (grid, data acquisition, etc)

7. budget Tier-1 Desktops, NIKHEF analysis facility
budget for new investments
short term (2006 – 2007): 2,8 M€ from NCF; Tier-1 part ~ 0,6 M€
mid term (2007 – 2010) : 2 M€ / yr from NCF; part of NCF long-range plan but funds not yet secured.
Budget for maintenance included in above figures
Desktops, NIKHEF analysis facility
New investments 170 k€
Maintenance & overhead 160 k€
Extra funding for analysis facility from NIKHEF discretionary budget if necessary

8. Progress at NIKHEF LHCb DC ‘04
Up to 3000 simultaneous “jobs” per experiment
2.2 million CPU-hours (250 years) used in one month
Total data volume > 25 TB
For LHCb: NIKHEF ~ 6% of global total
