Automatic Code Generation Method of DEQSOL (Differential EQuation SOlver Language)

概要

論文の詳細を見る
DEQSOL is a high-level programming language specially designed to describe PDE problems in quite a natural way for numerical analyses. This language has two design targets. One is to enhance programming productivity by establishing a new architecture-independent language interface between numerical analysts and vector/parallel processors. The other is to automatically generate highly vectorizable FORTRAN codes from DE-QSOL descriptions, thus realizing efficient execution. The DEQSOL translator automatically generates highly vectorizable simulation codes using intrinsic parallelism remaining in DEQSOL descriptions. As a discretization method, both FDM and FEM are provided. The key techniques of the translator are the symbolic manipulation to discretize PDE and the code generation utilizing maximum DO-loops. DEQSOL has been applied to over 30 Practical Problems, and the above targets are successfully attained. Productivity, when measured by the required source's lines-of-code, is improved by almost one order of magnitude over FORTRAN programming. Also, most of the generated FORTRAN codes have extremely high vectorization ratios (91%-96%) on the HITACHI S-810/20 vector processor.
