BEAM DYNAMICS CALCULATIONS AND PARTICLE TRACKING USING MASSIVELY-PARALLEL PROCESSORS

During the past decade massively parallel processors (MPPs) have slowl y gained acceptance within the scientific community. At present these machines typically contain a few hundred to one thousand off-the-shelf microprocessors and a total memory of up to 32 GBytes. The potential performance of these machines is illustrated by thr fact that a month long job on a high end workstation might require only a few hours on a n MPP. The acceptance of MPPs has been slow for a variety of reasons. For example, some algorithms are not easily parallelizable. Also, in t he past these machines were difficult to program. But in recent years the development of Fortran-like languages such as CM Fortran and High performance Fortran have made MPPs much easier to use. In the followin g we will describe how MPPs can be used for beam dynamics calculations and long term particle tracking.
