Ian, Per your suggestions, I reran my original timing experiments using: (a) mach_absolute_time() for time measurements, and (b) random (uniformly distributed) input data: - 100 * drand48() for sqrt -vice- vvsqrt tests, & - 20π * drand48() for sin -vice- vvsin tests. The results are similar to the original set but showing somewhat better vForce/scalar performance in both cases; - ~22.5 nsec/input value for vvsqrt() vice ~30 nsec for scalar sqrt() loop, & - ~44 nsec/input value for vvsin() vice ~53 nsec for scalar sin() loop. These were run, as before, using 10,000 pt input sets and (to my satisfaction) seem in general agreement with your & Jeff Biggus' graphs. _______________________________________________ Do not post admin requests to the list.
