Abstract
There is no explicit way for parallelization of DOACROSS loops in the HPF specifications. Although recent advanced HPF compilers such as HPF/ES have been as powerful as MPI in many situations of parallel programming, many of them do not have the capability of pipelining DOACROSS loops. We propose a new extension for pipelined parallelization, the PIPELINE clause, and have developed a preprocessor, named HPFX, that translates an HPF source program annotated by the PIPELINE clause into a normal HPF one, to evaluate the effectiveness of the clause. Evaluation on the Earth Simulator shows that pipelined parallelization in implementations of the NPB LU benchmark with HPFX and HPF/ES outperforms the hyperplane parallelization in the conventional HPF implementations of the benchmark.
