flops.c is a C program which attempts to estimate your system's floating-
|
|
point 'MFLOPS' rating for the FADD, FSUB, FMUL, and FDIV operations based on
|
|
specific 'instruction mixes' (discussed below). The program provides an
|
|
estimate of PEAK MFLOPS performance by making maximal use of register
|
|
variables with minimal interaction with main memory. The execution loops
|
|
are all small so that they will fit in any cache. The flops.c execution
|
|
modules include various percent weightings of FDIV's (from 0% to 25% FDIV's)
|
|
so that the range of performance can be obtained when using FDIV's. FDIV's,
|
|
being computationally more intensive than FADD's or FMUL's, can impact
|
|
performance considerably on some systems.
