A Compiling Framework Based on Uniform Partitioning Schemes for Parallel Loops

Compilation of parallel loops is one of the most important parts in parallel compilation and optimization. This paper mainly discusses the key techniques during the compilation implementation of parallel loops, based on the uniform partition schemes. It includes techniques in local array index generating, loop space reconstructing, communication detecting and organizing and data dependence disposing. The efficiency of this implementation has been proved by lots of experiments. The p_HPF compiler which adopts this compiling framework can obtain good speedups and efficiencies. The compiler has been applied in many fields, particularly the field of petroleum exploration.Compilation of parallel loops is one of the most important parts in parallel compilation and optimization.
