High performance of mathematical functions is essential to speed up scientific calculations because they are very frequently used in scientific computing. This paper presents performance of important Fortran intrinsic functions on the fastest vector supercomputers. It is assumed that a relationship between CPU-time and the number of function arguments given to calculate function values is linear, and speeds of a function were measured using the parameters and . The author also examines how the speed of the function varies with respect to the selection of arguments. The computers tested in the present paper are Cray C9016E/16256– 4, Fujitsu VP2600/10, Hitachi S-3800/480 and NEC SX-3/14R.
