• 20 mins Data Grid (SL)

• 20 mins General discussion• SJ – animator

Technology Tracking

• PASTA– Are current requirements (from experiments) realistic ?

– Can we manage 20,000 processors ?

– Could we survive without ‘active’ data on tape ?

– Other issues

• WAN/LAN– Will AODs be transferred to the desktop ?

• Do we actually need 100 Gbe?

– What if we cannot afford 622 Mb/s to (all) Regional Centres ?

– What about the enormous ratio LAN/WAN ?

– Other issues

Technology Tracking

• Grids– Will the computing be organised as a HEP Grid ?– If there was a commercial INTEL/Seagate public

grid…• Couldn’t HEP just rent CPU and disk space ?
