This chapter presents benchmark results to illustrate performance obtained using the Fortran 90D/HPF compiler. The chapter shows the portability and scalability of the Fortran 90D/HPF compiler. It gives the performance results for different distributions. The chapter also compares the Fortran 90D/HPF generated code with the hand-written Fortran 77 + message passing codes to show that overall performance of Fortran 90D/HPF compiler and its run-time system is comparable to hand-written codes.
