Abstract

We are developing a Fortran 90D compiler, which converts Fortran 90D code into Fortran 77 node programs for distributed memory machines. This paper presents the performance results of Fortran 90D intrinsic functions on Intel iPSC/860 and iPSC/2 hypercubes. We discuss the implementation of these intrinsic functions and show that our implementations are scalable.
