Steven C. Neighorn:

Thanks for the benchmark results.  The Sieve and Savage results ( SIEV.EXE
87BENCH.EXE, and 88BENCH.EXE ) are interesting to me because I have run
these on a Commodore-Amiga Turbo-Amiga ( 68020/68881 running at 14.32 MHz ).
The Savage took 0.39 seconds and the Sieve 0.8 seconds at 14.32 MHz with
32-bit memory.

What I am wondering about is:  (1) What Language did you use, and (2)
could you upload the Sieve and Savage programs because I'm not sure that
I was running the same code as yourself (even though the program names are
the same).

I ran Gibreath's Sieve using Lattice C.  The Savage was run with Absoft's
68020/68881 compiler for the Amiga.  I found that IEEE single precision
was quick but grossly inaccurate in running the Savage so I ran it in
double precision.

Thanks.
