Latest flops.c results, MFLOPS(2), are included below.

The most recent program version (flops20.c) and latest results
(flops_1.tbl, flops_2.tbl, flops_3.tbl, and flops_4.tbl) are available
via anonymous ftp from 'marlin.nosc.mil' in directory 'pub/aburto'. The
'marlin' host number is: 128.49.16.4

I'd appreciate any new results of any kind (new machines, compilers,
compiler options). I will also periodically post results to
'comp.benchmarks'. Send results to: aburto@marlin.nosc.mil. Thank you
very much ...

FLOPS C Program (double precision) Version 2.0,  18 Dec 1992

MFLOPS(2) Weightings: FADD 38.2%, FSUB 9.2%, FMUL 43.4%, FDIV 9.2%.
          The code for MFLOPS(2) is fully vectorizable. The percentage
          of FDIV's however is somewhat on the 'high' side.               -

Results as of 19 Jan 1993:
