After completing the floating-point calculation
, the result will be converted into fixed-point numbers for output.
One TERAFLOP is a floating-point calculation
speed based on 1 trillion occurrences every second.
Double-precision performance is more important for supercomputing applications as it carries higher precision for floating-point calculations
than single-precision calculations.
Add complex floating-point calculations
into the mix, and the need for major advancements in processing power becomes obvious.
At a press event in San Francisco, USA, AMD demonstrated a 'Teraflop in a Box' system running a standard version of Microsoft Windows XP Professional that leveraged AMD Opteron dual-core processor technology and two next-generation AMD R600 Stream Processors capable of performing over 1tn floating-point calculations
per second, using a general 'multiply-add' (MADD) calculation.
Altogether, the 768 SGI 400 MHz processors from the two SGI Origin 3800 systems will help to quadruple ARL MSRC's computing power, making the facility one of the world's top 10 most powerful computer sites with a data rate of approximately 2 trillion floating-point calculations
Speedy floating-point calculations
are essential for applications that require sophisticated design, analysis and three-dimensional visualization capabilities, like mechanical crash simulation and computational fluid dynamics.
are critical to technical applications, such as seismic/petroleum exploration, aircraft design analysis, weather forecasting and computational fluid dynamics.
The Clipper workstations, for example, make floating-point calculations
about twice as fast as they make integer calculations.
