Summary:Certain problems in the field of stellar atmospheres, polarized radiative transfer and magnetic field diagnostics cannot be addressed by means of traditional sequential programming techniques because CPU times become prohibitive on even the fastest single processor machines when realistic physics and accurate numerical methods are employed. This contribution discusses the question of what kind of supercomputing approach is best suited for the modelling of Ap stars, pointing out the superiority of parallel computing with Ada95 over High Performance Fortran in all of the above-mentioned fields.
