Large-Scale Computing  Nucleus-Nucleus Collisions and the  How to proceed

   
Theory

In theoretical studies of matter at extreme temperatures and densities, a common problem has emerged in recent years. The evaluation of large and complex systems of many degrees of freedom becomes possible only if theorists have access to high performance computational facilities and sufficient manpower. For the experimental investigation in this field, considerable investments are being made and will be made in Europe during the next decade. To assure that the resulting data indeed lead to the anticipated increase in our understanding, a commensurate support must be provided for the associated theoretical work. In particular, this requires:

• a European facility for large-scale computing in the field;
• support for the manpower and the training of young theorists and for their needed computational equipment;
• a European forum for the crucial interchange between theory and experiment.
