1. Dave Newbold, University of Bristol8/3/2001 UK Testbed 0 Sites Sites that have committed to TB0: RAL (R) Birmingham (Q) Bristol (Q) Edinburgh (Q) Imperial College (Q) Liverpool (R) Manchester (Q) Oxford (Q) QMW (Q) Lots of other UK sites interested in GRID …will join later testbeds.

2. Dave Newbold, University of Bristol8/3/2001 Comments on TB0 Need some policies on ‘small’ sites: How will they contribute? Are they useful in the quantum state? Can we have a clear set of requirements / guidelines. Support services in the UK: CA @ RAL GLOBUS support mailing lists GLOBUS (+ other tools) in RPM form More manpower coming soon: 6 people (50% WP6) to be appointed in the next few weeks Distributed at 6 sites

3. Dave Newbold, University of Bristol8/3/2001 Resources Two ‘large’ sites signed up RAL CSF cluster GLOBUS-enabled (oo 100 CPU, TB disks, 10’s TB tape) Not all for TB! A dedicated cluster has been ordered + will arrive soon: 10’s CPU, TB disks. Liverpool MAP: A prototype Tier-2 facility Some fraction available for TB use - discussing Network SuperJanet IV (‘production’ network for UK Universities) 2.5GB/s to all (?) sites now - but not locally within institutes yet! 10GB/s by TB2...

4. Dave Newbold, University of Bristol8/3/2001 Security CA set up: Works! (thanks to Andrew Sansum) …but very laborious (isolated CA machine => floppy disks!) Some 10’s of certificates granted to existing CSF users Can potential grant to outside users - will define policy very soon Policies: Account activity must be traceable to an individual ‘Manual’ checking of identity required now Likely to be similar for Universities No restrictions on use of ‘quantum’ facilities by experiments …but will review this after TB0 startup

5. Dave Newbold, University of Bristol8/3/2001 IS + apps Information service Modelled on the TB0 proposal: Single top-level server (at QMW - Alex Martin) o=grid, o=ukhep… Each site has a server (so a two-level tree) Applications LHC production - LHCb and CMS (soon + now!) BaBar interest, with possible new central facility CDF / D0 / others… all interested to use GRID facilities How do we accommodate them all? Probably need several working releases of software at a time...
