Why the speed of a supercomputer is expressed in FLOPS?
Floating-point operations per second, or FLOPS, is the unit of measurement that calculates the performance capability of a supercomputer. A FLOPS reading alone isn’t enough to precisely gauge the Rpeak of a supercomputer. A number of different, intricate tests need to be run before a final figure is reached.
How is the processing speed of a supercomputer measured?
Supercomputing is measured in floating-point operations per second (FLOPS). Petaflops are a measure of a computer’s processing speed equal to a thousand trillion flops. And a 1-petaflop computer system can perform one quadrillion (1015) flops.
How does high performance computing work?
High performance computing (HPC) is the ability to process data and perform complex calculations at high speeds. One of the best-known types of HPC solutions is the supercomputer. A supercomputer contains thousands of compute nodes that work together to complete one or more tasks. This is called parallel processing.
How many FLOPS is the fastest computer?
In June 2007, Top500.org reported the fastest computer in the world to be the IBM Blue Gene/L supercomputer, measuring a peak of 596 teraFLOPS. The Cray XT4 hit second place with 101.7 teraFLOPS.
Why is performance measured in FLOPS?
While clock speed, which is measured in megahertz, is often seen as an indicator or a processor’s speed, it does not define how many calculations a processor can perform per second. Therefore, FLOPS is a more raw method of measuring a processor’s processing speed.
How are FLOPS calculated?
The basic idea is to take the number of floating-point calculations that can be performed in a single processor clock cycle (four, usually) multiply it by the processor’s clock speed and then scale it by the number of available cores per socket connecting them.
What is the speed of supercomputer?
The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, there are supercomputers which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS).
What is a supercomputer and what is it used for?
supercomputer, any of a class of extremely powerful computers. The term is commonly applied to the fastest high-performance systems available at any given time. Such computers have been used primarily for scientific and engineering work requiring exceedingly high-speed computations.
What does high performance computing mean?
High Performance Computing most generally refers to the practice of aggregating computing power in a way that delivers much higher performance than one could get out of a typical desktop computer or workstation in order to solve large problems in science, engineering, or business.
What is the speed of Summit supercomputer?
148.6 petaFLOPS
Poised at the Summit. Since its debut on the June 2018 list, Summit improved its initial High Performance Linpack (HPL) performance from 122.3 to the current 148.6 petaFLOPS.
