Intel Lifts the Hood on its "Single-Chip Cloud Computer"

A 48-core prototype processor is part of a move from supercomputer-on-a-chip to data-center-on-a-chip

9 February 2010—Chips that can simulate a supernova or predict a hurricane are yesterday’s goal, if Intel’s recently unveiled 48-core research chip is any indication. Today’s goal is squeezing all the simple but extensive work of a data center onto a single chip. Big IT firms have huge, sophisticated networks of servers, says Justin Rattner, Intel’s chief technology officer and director of Intel Labs. But ”they’re not computing the mass of a proton,” he says. ”They’re searching for the needle in a haystack.”

In response to the need for better, faster data mining, Intel Labs has developed what it’s calling a single-chip cloud computer. The 1.3-billion-transistor research chip, the company reported yesterday at the IEEE International Solid-State Circuits Conference, consists of 48 Pentium-class IA-32 cores formed into a network of 24 tiles. Each tile has two cores plus one router to allow intercore communication. The keys to its efficiency at handling needle-in-a-haystack-type tasks are two new software-based techniques: one for rapidly transferring data between its many cores and the other for controlling the power those cores consume.

The Ultimate Transistor Timeline

The transistor’s amazing evolution from point contacts to quantum tunnels

Even as the initial sales receipts for the first transistors to hit the market were being tallied up in 1948, the next generation of transistors had already been invented (see “The First Transistor and How it Worked.”) Since then, engineers have reinvented the transistor over and over again, raiding condensed-matter physics for anything that might offer even the possibility of turning a small signal into a larger one.
