Speaker: Paul AveryThe LHC era brings unprecedented challenges in information technology: (1) providing rapid access to massive data stores of 100 PB or more and (2) providing transparent access to heterogeneous computing resources throughout the world across an ensemble of networks of varying capability and reliability.
I discuss here how these challenges can be met by a hierarchical computational Grid of data analysis centers linked by Gbps networks. Such a Grid will allow physicists to play key roles in all stages of the data analysis, from development of the reconstruction programs and software infrastructure, to the extraction of first physics results. This capability will be extended to physicists at their home institutions through the use of an integrated distributed Grid system architecture designed for efficient PetaByte-scale data access and analysis.
Several Grid projects are already underway. The network-monitoring and control software, and the modeling and optimization systems and methods, will be widely applicable functional components that should also drive the design and implementation of future distributed systems in HEP and many other fields of science, engineering and industry.
