Here are the results. #define ITERATIONS 100 e_afpa 12.4u 0.1s 0:13 96% 11+23k 0+1io 3pf+0w afpa 12.8u 0.1s 0:13 94% 12+23k 0+0io 5pf+0w mc881 16.2u 0.0s 0:16 97% 11+23k 0+0io 3pf+0w #define ITERATIONS 1000 e_afpa 123.3u 0.2s 2:04 99% 12+23k 0+1io 5pf+0w afpa 127.2u 0.1s 2:08 99% 12+23k 0+1io 5pf+0w mc881 161.0u 0.1s 2:41 99% 12+23k 0+1io 7pf+0w If you're interested, here is where you can get the program that I used. /* Written 4:09 pm Jul 27, 1989 by davies@uicsrd.csrd.uiuc.edu in m.cs.uiuc.edu:general */ Argonne National Laboratory has an automatic system for fetching various public-domain software (mostly Fortran numerical code, but also some in other languages) that includes these and other benchmarks. The following was returned to me by e-mail by sending a mail message to: netlib@anl-mcs.arpa with the body of the message being: send index from benchmarks. To get e.g. whetstone.c, put this in the message: send whetstonec from benchmarks. To get general information about netlib, try: send index.
