This paper compares a high-level implementation of the NAS benchmark FT in the functional array language SAC with traditional solutions based on FORTRAN-77 and C. The impact of abstraction on expressiveness, readability, and maintainability of code as well as on clarity of underlying mathematical concepts is discussed. The associated impact on runtime performance is quantified both in a uniprocessor environment as well as in a multiprocessor environment based on automatic parallelization and on OPENMP.
