Fast exponential calculation for the IBM 370-195 at the Oak Ridge Gaseous Diffusion Plant
J. C. Whitson, J. H. Whealton · 1977
The time spent for computing an exponential for the IBM 370-195 at the Oak Ridge Gaseous Diffusion Plant is about 25 times slower than that spent by the CDC-7600 CTR computer at Livermore. We propose a scheme which does not involve a function call, is 15 times faster than the IBM 370-195 scheme, and is useful when the exponential is called many times.
