Large-Scale Computing

The fundamental thermodynamics of strong interactions can only be evaluated by computer simulation of lattice QCD at finite temperature and density. These studies form the basis for the experimental investigation of hot and dense strongly interacting matter. They require extensive numerical work on the most powerful high performance computers, and if in Europe such facilities are not available and maintained at the latest technological level, basic research in this field is no longer possible here. The theoretical analysis and the simulation of events produced in high energy nuclear collisions requires the processing of unprecedented amounts of data and therefore advances in computer technology, analysis algorithms, and access to large computational facilities. It is also necessary to facilitate the access of theory groups to such facilities and to provide sufficient up-to-date computing power for their needs. In both areas, there exists a broad and experienced European community able to solve the mentioned problems, if it is provided with the necessary computational infrastructure. To remain internationally competitive, it is essential to establish a dedicated European facility of the highest technological standard to address the study of complex systems in nuclear physics. Such a facility should be operated by a group experienced in large scale computational physics and made accessible through high speed networks to all European groups in the field.
