What is HPF ?

HPF (High Performance Fortran) is a parallel language that is an extension of Fortran. All that users of HPF need do to parallelize their programs is to specify the data layout with some simple directives, and the remaining tasks, communication generation and computation partitioning, are handled automatically by the compiler.

The HPF language specification was discussed by HPFF (High Performance Fortran Forum), which is a coalision of industrial and academic groups of USA, and the HPF 1.0 language specification was established in 1993. In 1997, to fix ambiguous specifications and provide advanced extensions, the specification of HPF 2.0 and approved extensions were released. In 1999, Japan Association of High Performance Fortran (JAHPF), which is the forerunner of HPFPC, defined the specification of the HPF/JA 1.0 extensions to make HPF more useful.

HPF has the following features:

An extension of Fortran
The HPF language is defined as a set of directives to be inserted into conventional Fortran programs.
Data parallel
Parallelism of programs is extracted from the iterations of DO loops, FORALL loops and array statements.
High abstraction
User can parallelize their programs only by specifying data layout with some simple directives.

Earth Simulator Project "Performance Evaluation of Large-scale Parallel Simulation Codes and Designing New Language Features on the HPF (High Performance Fortran) Data-Parallel Programming Environment"
We have carried out the project in corporation with the Earth Simulator Center since 2002. The achieved results in 2002 are as follows:
- We parallelized a three-dimensional fluid simulation code called IMPACT-3D with HPF/ES, and achieved the performance of 14.9 Tflops (45% of the peak) for the mesh size of 2048x2048x4096, in the execution on 512 nodes of the Earth Simulator.
- We evaluated some benchmark programs from the NAS Parallel Benchmarks and HPFBench benchmark suite and revealed some requirements of improvements of HPF/ES.
