      abstract     = {Today, numerical simulation is used more and more to get
                      detailed information about crystal growth processes. In the
                      Czochralski crystal growth from electrically conductive
                      melts, the application of an external magnetic field has
                      become a very useful technique for improving crystal
                      quality. The integration of the magnetic field into the
                      simulation program leads to a system of coupled partial
                      differential equations, i.e. incompressible Navier-Stokes
                      equations and convective heat equations in combination with
                      an external magnetic field, which have to be solved. Because
                      of the regular access to data this problem is suitable for
                      vector computers. The CRAY X-MP provides vectorization and
                      multiprocessing capabilities. With multitasking it is
                      possible to run different parts of one program in parallel.
                      Both multitasking concepts, macrotasking and microtasking,
                      were examined to evaluate their potential to speed-up the
                      Czochralski crystal growth simulation program implemented on
                      a CRAY X-MP. We will give a survey of the application, and
                      will describe the concepts of macrotasking and microtasking
                      on the CRAY X-MP architecture as well as the integration of
                      these concepts into the simulation program. Timing results
                      provide information about the user benefit obtained by using
                      these techniques.},
