1 Gigabyte Bandwidth Enables Global Co-Laboratories Prof. Harvey Newman, Caltech Jim Gray, Microsoft Presented at Windows Hardware Engineering Conference Seattle, WA, 2 May 2004

2 Analysis and development GlobalDistributedCooperative Massive amounts of data ~1 Gigabytes per second ~20 Petabytes per year Gigabyte bandwidth required ,000+Physicists 250+Institutes 60+Countries Today 500+ Physicists 100+ Institutes 100+ Institutes 35+ Countries 35+ Countries CMS Atlas Challenges Faced by Global Science Experiments

3 LHC Datal Grid Hierarchy Developed at Caltech 30 Petabytes by Exabyte by 2014 ~5 GBps CERN Filter Tier 0 +1 Tier 2 Tier 3 Tier 1 … INP3RALINFNFNAL Tier 2 Institute Tier 2 Institute Tier 4 Experiment ~1 GBps ~PBps.1 GBps Physics data cache ~1 GBps Workstations
