Welcome to the Feynman@Home France-Japan-CERN Collaboration.
This project is an attempt to solve both CPU and memory issues related to the automatic computation of complex
LHC and linear colliders
CLIC) physics processes.
High precision floating point calculations (>= quadruple precision) are often necessary to address the integration of singular amplitudes which imply CPU intensive computations. In addition, complex processes lead to very large multi-dimensional integrants often in the multi-Gbyte range. We are insvestigating weither Distributed Computing (Public or volonteer based) or/and the GRID can bring efficient solution to these needs.
Public Distributed Computing, Based on the development of an improved version of BOINC for multi-client code and soft synchronization it offers, in return, a live presentation of current HEP and Astrophysics programs and projects in the hope to increase the public understanding and interest to fundamental research.
package (KEK) for helicity amplitude code generation, it implements the multi-dimensional phase space integration (BASES) and event generation (SPRING ) packages in the framework of an hybrid computing system combining the GRID or dedicated clusters and public distributed computing.
Target physics processes will be selected both by the collaboration members and, through a self-service approach, by any physicist interested in a particular physics issue.
We will be focusing on :
user/system interface to the GRACE Package
High precision floating point calculations
"Public" and "private" Distributed Computing: Feynman@Home and the GRID
