Intel shows off its Knights Corner one teraflop chip
Intel shows off its newly developed accelerator chip, Knights Corner, capable of hitting speeds of one teraflop. The new chip was demonstrated on a test machine at the Supercomputing Conference in Seattle.
Knights Corner packs in more than 50 cores onto a single piece of silicon offering “double precision” processing allowing for greater numbers to be posted at one time. Intel also says its accelerator is its first server processor to support PCI Express 3.0 integration specification allowing for 32 gigabytes per second transfers to devices that are compatible.
While Intel’s co-processor relies on the same instruction set architecture as its popular x86 processors, its rivals are taking a different approach.
They are offering chips known as graphic processing units (GPUs) which are designed to carry out the calculations necessary to draw, colour and shade objects on the screen at high speed.
They specialise in processes that can be broken down into several parts, where the output of one calculation does not affect the input of another. This makes them particularly well suited for other tasks such as speech recognition and image processing.
However, developers need to code their software in order to take best advantage of GPUs.
