HPC Centres
Contribute to the acceleration of scientific discovery, by the use of information technologies
Provide high performance supercomputing environments for dealing with science’s more challenging problems.
Act as a technology transfer agent between R&D in information technologies, and computational science

Targets for HPC in next decade
Capture more physics in the simulation of complex systems
Complex systems are characterized by multiple time and/or length scales
Not easy to capture multiple scales in one code
Code coupling for multi-physics applications is viable alternative in some conditions
This leads naturally to computational grids
Heterogeneous algorithms map naturally to heterogeneous grids.

Project motivations and strategies
Focus on heterogeneous, very high performance supercomputing environments.
Use of grid technologies to provide a unified image and a transparent access to such environments
Deploy an application testbed across Europe by the integration of partner’s HPC environments
Provide a major effort to develop and deploy distributed scientific applications (EUROGRID is roughly 2/3 applications development, 1/3 technology development)

EUROGRID middleware
MPI (scientific standard, soon interoperable)
CORBA - JAVA (internet standard, has significant software engineering advantages, but not yet fully adapted to performance focused complex applications).
