Introduction
You would have worked with KHz(Kilo-Hertz) micro-processors in the past; MHz(Mega-Hertz) speedy ones lately; THz(Tera-Hertz) processors too are available for the lucky ones. This article studies on the research and development thats happening elsewhere in the world, manufacturing EHz(Exa-Hertz) processors.
Ticking of the Clock
MHz processing allows you to compute million calculations(10E6) per second.THzprocessing allows you to compute trillion calculations(10E9) per second. The Sandia National Laboratories based in New Mexico, USA has come up with a plan to produce computers at the exascale range(EHz) that would perform million trillion calculations per second. One EHz is equivalent to one Quintillion(10E18) hertz.
So, what's there in it?
One aim, one of the Sandia's architect says, is to reduce or eliminate the growing mismatch between data movement and processing speeds.
Processing speed refers to the rapidity with which a processor can manipulate data to solve its part of a larger problem. Data movement refers to the act of getting data from a computer’s memory to its processing chip and then back again. The larger the machine, the farther away from a processor the data may be stored and the slower the movement of data.
“In an exascale computer, data might be tens of thousands of processors away from the processor that wants it,” says Sandia computer architect DD. “But until that processor gets its data, it has nothing useful to do. One key to scalability is to make sure all processors have something to work on at all times.”
Conclusion
As the scientists faces the challenge of the data utilization by the processor, we should invent and improve our ways of data movement targeting the high-capacity processor. The big question remains here: Do we have a transportation mechanism to transfer data inside a computer, at the speed of light?
