NIKHEF SARA

• NIKHEF by itself not big enough
• 200 PCs on the desktop (NT and Linux) and
• 200 unix workstations on the desktop (Sun, SGI.
  HP)
• 20 institute servers
• PC farms
• 155 Mb network
• SARA NIKHEF together much more interesting
• See presentation of Paul Wielinga !
• Large CPU capacity
• Large disk and tape storage facilities
• Expertise
• Very good connectivity

SARA

• Dutch National Supercomputer
• CRAY C90 now
• SN1-MIPS with 1024 CPUs and 1 TB RAM
• Other large mpp systems from SGI/Cray and IBM
• All inter connected by 155 Mb/s
• External connections Dutch Nat.Acad.Broadband
  Netw.
• SURFnet4 622 Mb/s backbone now
• SURFnet5 10 Gb/s (Giganet) later this year
• Plans for 1 or more PC clusters
• Storage Area Network
• 50 TB disk storage
• 240 TB tape storage
• CAVE high-end 3D VR environment

Possible HEP Testbed

• National
• D0 Monte Carlo calculations and reconstruction
• At NIKHEF on a Linux PC farm
• In Nijmegen on a Linux PC farm
• At SARA on the SGI Origin and/or Linux PC farm
• Mass storage management
• Using SARAs taperobot
• Wide-area
• D0 Monte Carlo calculations and reconstruction
• At CCIN2P3 on a Linux PC farm
• In Prague on a Linux PC farm
• In Arlington,Texas on a Linux PC farm
• Mass storage management
• Using Fermilabs taperobot

Contributions

• NIKHEF SARA
• intend to contribute 8 ftes
• existing infrastructure
• From additional funding
• another 4 ftes
• more infrastructure
• Interested parties in The Netherlands
• Dutch National Computing Facility NCF
• Dutch Academic Service Provider SurfNet
• Government sponsored program ICES/KIS (Gigaport)

Non-HEP interests

• Dutch Meteorologists (KNMI)
• See contribution of Wim Som de Cerff
• (?) Maybe Dutch biologists and nedical faculty
• Through SARA and WCW
• (?) SARA also has good connections with
  industrial partners
• Interested parties from the previous slide
• Dutch National Computing Facility NCF
• Dutch Academic Service Provider SurfNet
• Government sponsored program ICES/KIS (Gigaport)
• (?) means that no official contacts have been
  made yet
