THE LIVERMORE FORTRAN KERNELS: * SUMMARY *

********************************************

        Computer : HP Vectra XU 6/150, 150 MHz Pentium Pro

        System : Windows NT 4.0

        Compiler : DEC f90, full optimization

        Date : 1998 July 24

When the computer performance range is very large

the net Mflops rate of many Fortran programs and

workloads will be in the sub-range between the equi-

weighted Harmonic and Arithmetic means depending

on the degree of code parallelism and optimization.

The least biased central measure is the Geometric

Mean of 72 rates, quoted +- a standard deviation.

Mean Mflops rates imply the average efficiency of a

computing system since the peak rate is well known.

LFK test measures a lower bound for a Multi-processor

and N * LFK rates project an upper bound for N-procs.
