Sounds like the old lines of "I work on an X (fast computer): it can do an infinite loop in 6 seconds." "Well, I work on Y (multiprocessor): it takes a little longer to do an infinite loop, but it can do N of them at once." Maybe Dhrystone 2.0 (Dhryer-stone?) will not be such a pushover. (More seriously, we look forward to 2.0: sounds good, especially if the statistics are closer to more typical programs; it will be wonderful to stop ahving to write reams of words to give reasonable explanations of optimization effects.) -- -john mashey DISCLAIMER: UUCP: {decvax,ucbvax,ihnp4}!decwrl!mips!mash OR mash@mips.com DDD: 408-991-0253 or 408-720-1700, x253 USPS: MIPS Computer Systems, 930 E.
