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

• Grids
• Will the computing be organised as a HEP Grid ?
• If there was a commercial INTEL/Seagate public
  grid
• Couldnt HEP just rent CPU and disk space ?
