flops

Nevertheless, an approximate comparison can be made based on the MFlop (million floating point operations per second) values of the processors on which the algorithms were coded and run [37].

5, that being the Greatly Reduced Array of Processor Elements with Data Reduction (GRAPE-DR) system at the National Astronomical Observatory of Japan, which produced 429 Mflops per watt.

The results are given (in MFlops) for execution of 2.3....

In this case, for order 0 and 1 we have the same number of Mflops and iterations for some [[sigma].sub.1] and, in three runs, the same (rounded) number of Mflops but a different number of iterations for order 2 (necessarily lower because more expensive than order 0 and 1).

In terms of performance, the direct tridiagonalization runs at roughly 75 MFlops, while the reduction to banded form reaches 220 MFlops, more than half of the processor's peak performance.

This machine contains four 332MHz PowerPC 604e processors, each with a peak performance of 664 Mflops. We refer to this simple benchmark as MATMUL.

In terms of raw number crunching, the 200MHz Power3 could in theory crank out about 800 MFLOPS, with about 630 MFLOPS realized on benchmark tests.

Each processing node of the CM-5 is equipped with a 32MHz SPARC v7 processor rated at a peak performance of 32 Mips or 5 MFlops.(6) The experiments were run on a 32-processor system running version 7.3 Final I Rev 3 of the CMOST operating system, with version 3.2 of the CMMD message passing library.

(1) Mtops (millions of theoretical operations per second) are roughly comparable to millions of floating-point operations per second (Mflops), but take into account integer computation, variations in word length between systems, and can serve to rate the performance of low- as well as high-end computers.

2) power consumption, e.g., millions of floating point operations per second (MFLOPS) per watt, an important military consideration, is less in the DSP chip

For example, a typical computing time for analyzing a metal insert filter with 15 modes is 10 seconds for each frequency point on a typical, common, low-cost workstation with 10 MFLOPS. A typical complete diplexer may be optimized within a one-day run.
