document: Three-dimensional global MHD simulation code for the Earth 's magnetosphere using HPF/JA We have translated a three-dimensional magnetohydrodynamic -LRB- MHD -RRB- simulation code of the Earth 's magnetosphere from VPP Fortran to HPF/JA on the Fujitsu VPP5000/56 vector-parallel supercomputer and the MHD code was fully vectorized and fully parallelized in VPP Fortran . The entire performance and capability of the HPF MHD code could be shown to be almost comparable to that of VPP Fortran . A three-dimensional global MHD simulation of the Earth 's magnetosphere was performed at a speed of over 400 Gflops with an efficiency of 76.5 % using 56 processing elements of the Fujitsu VPP5000/56 in vector and parallel computation that permitted comparison with catalog values . We have concluded that fluid and MHD codes that are fully vectorized and fully parallelized in VPP Fortran can be translated with relative ease to HPF/JA , and a code in HPF/JA may be expected to perform comparably to the same code written in VPP Fortran
