US CMS + US ATLAS ITR (pre-)proposal “Globally Enabled Analysis Communities”. Sound Bites: “Dynamic workspaces” “Private Grids to support scientific analysis communities” “Build autonomous communities operating within global collaborations”
“Private Grids to support scientific analysis communities”
“Build autonomous communities operating within global collaborations”
“Empower small groups of scientists to profit from and contribute to international big science”
“Democratization of Science via new technologies”
What is it? Well, we will have to define it in the proposal, due in March 2003
by current projects
other grid nodes for physics,
biology, medicine, ….
Development of A Science Grid Infrastructure (L.Robertson)
Hardware: Computers, Storage (permanent and temporary)
Software Packages: physics, framework, data management, build and distribution mechanisms; base infrastructure (operating systems, compilers, network, grid);
Event and Physics Data and Datasets
Schema which define: meta-data, provenance, ancillary information (run, luminosity, trigger, Monte-Carlo parameters, calibration etc)
Organization, Policy and Practice
Analysis Groups - Communities - are of 1 to many individuals
Each community is part of the Enterprise :
Is assigned or shares the total Computation and Storage
Can access and modify software, data, schema (meta-data)
is subject the overall organization and management
Each community has local (private) control of
Use of outside resources e.g. local institution computing centers
Special versions of software, datasets, schema, compilers
Organization, policy and practicePhysics Analysis in CMS
We must be able to reliably and consistently move resources & information in both directions between the Global Collaboration and the Analysis Communities
Communities can share among themselves.
X - physicist
So - software
Sc - schema/information
a private grid/analysis community
The CS and IT part of the proposal!
Meta-data to describe and manage private grids.
Tools for information and data transfer and communication between communities
Synchronization and validation tools between the community grids and the global enterprise.
Application/user interfaces for management, administration and operation of set of private grids within an enterprise.
Rapid response reconfiguration and administration tools.
Enterprise wide integrity and validation tools across all private grids.
Application/user interfaces for the distributed request and control of extensions and contractions of private grids.
Mechanisms to support parallel evolution and resynchronization of decentralized heterogeneous local and enterprise schema.
Application interfaces for definition, modification of and access to local and enterprise schema.
And the LHC is 10 times larger in all dimensions.
