The latest batch of Dhrystone benchmarks have just been posted to comp.misc, and here are some numbers that may be of interest to Atari users. These are measured in mythical "Dhrystone/second" units, the two numbers for each compiler being without register variable declarations, and with 'em: Lattice 3.03.01 446, 450 Megamax 1.0 1063, 1136 And, just ran this one myself: Alcyon 4.14 877, 892 On a related topic, a week or two ago I ran a couple of crude tests to compare the speed of the Alcyon IEEE floating point math library routines with the FFP math library, and the IEEE library came out about *10 times* faster. Basic arithmetic operations seem to be about the same speed in both formats, except the IEEE divide is noticibly faster than the FFP divide. The Dhrystone program does not do any floating point, so if anybody is really interested in seriously comparing floating point speeds you'll have to come up with your own benchmark program. -Sandra Loosemore (sandra@cs.utah.edu)
