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.
