“…These HPF compilers are very reliable and facilitate getting good performance for real-world scientific applications [9][10][11][12]. JAHPF is now expanded into a new organization, HPF Promoting Consortium (HPFPC) [13], where various HPF promotion activities are supported.…”

We succeeded in getting 14.9 TFLOPS performance when running a plasma simulation code IMPACT-3D parallelized with High Performance Fortran on 512 nodes of the Earth Simulator. The theoretical peak performance of the 512 nodes is 32 TFLOPS, which means 45% of the peak performance was obtained with HPF. IMPACT-3D is an implosion analysis code using TVD scheme, which performs three-dimensional compressible and inviscid Eulerian fluid computation with the explicit 5-point stencil scheme for spatial differentiation and the fractional time step for time integration. The mesh size is 2048x2048x4096, and the third dimension was distributed for the parallelization. The HPF system used in the evaluation is HPF/ES, developed for the Earth Simulator by enhancing NEC HPF/SX V2 mainly in communication scalability. Shift communications were manually tuned to get best performance by using HPF/JA extensions, which was designed to give the users more control over sophisticated parallelization and communication optimizations.

“…Recently, a Japanese computer vender, NEC, has released a HPF compiler equipped with the HPF/JA extensions [1] for the vector-parallel supercomputers, SX series and the Earth Simulator. The HPF compiler is very reliable and facilitates getting good performance for realworld scientific applications [2][3][4]. Since both OpenMP and HPF are directiveoriented paradigms for parallel programming, we are very interested in comparing their programming applicability and parallel performances.…”

OpenMP is a directive-oriented paradigm for parallel programming applicable to shared memory parallel computers. On the other hand, High Performance Fortron (HPF) is also a directive-oriented paradigm but for distributed memory machines. Thus, it could be very interesting to compare their programming applicability and parallel performances. We have converted four SPEC OMP 2001 benchmark programs, which are written with OpenMP and designed to evaluate the performance of shared memory parallel computers, into HPF, and evaluated parallel performances. We also point out problems that we had faced during conversion, and discuss solutions for them. Finally, we have improved the HPF performance by modifying the original source code. We could get good performance with HPF quite similar to OpenMP with SWIM, and moderate performance with APSI.
