标题： Supercomputing and Ap stars

摘要： 恒星大气、偏振辐射传输和磁场诊断领域中的某些问题无法通过传统的顺序编程技术来解决，因为在采用现实物理和精确数值方法时，即使在最快的单处理器计算机上，CPU时间也会变得难以承受。 本文讨论了哪种超级计算方法最适合于天琴座流星星的建模，并指出在上述所有领域中，使用Ada95的并行计算优于高性能Fortran。 显示英文摘要

摘要： 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.
