Abstract: The investigation of strongly interacting matter and its implications is one of the big challenges in modern physics. It is also a big challenge for computational science and for supercomputers especially, because many of very interesting aspects can only be studied numerically, using time consuming Monte Carlo simulations with large memory requirements. At KFA we supported a QCD-project of the Höchstleistungsrechenzentrum (HLRZ), an institution founded by the three german research centers KFA, GMD and DESY. In May 1989 the scientific council of the HLRZ decided to grant this QCD-project, called MTc-project, and to make about 20,000 CPU-hours on the CRAY Y-MP8/832 available to their investigations in one year. This project size makes it necessary to provide special adaptions and tuning arrangements in the operating system. Furthermore, it is highly essential to have a program which uses not only the vector but also the parallel hardware in an optimal fashion. This paper summarizes the optimization strategy and its realization.
