Intel Labs demos crazy-efficient, crazy-fast 'network on chip'

ISSCC Researchers at Intel Labs have come up with a "network-on-chip" that holds promise for more efficient, faster, and more versatile many-core processors. And no, this use of the term "network" doesn't mean hooking up a bunch of machines in a LAN, WAN, or whatever. This is a network inside a chip – specifically chips designed for …

Tilera preps many-cored Gx chips for March launch

Updated Upstart multicore RISC chip maker Tilera is timing the launch of its third generation of Tile processors to rain a little on Intel's forthcoming parade, and to try to blunt all of the excitement that is building for ARM-based alternatives for servers. Tilera will today begin sampling of its Tile-Gx series of processors. As El …

Intel code guru: Many-core world requires radical rethink

Intel is readying its many-core "Knights Corner" coprocessor for release next year, but programming the 50-core-plus beastie and its 100 or 200 core follow-ons will require a whole new approach to code wrangling. "Something that might have been only a couple per cent overhead at most in a one- or two-core system may become …

AMD ships low-cost six-core Phenom IIs

AMD's six-core Phenom II X6 processors have hit the streets, and the company claims that since they work with existing AM3 and AM2+ socket motherboards "with proper BIOS support," the move to six cores is "an easy upgrade." As The Reg reported last week, the two new processors are the 2.8GHz Phenom II 1055T and the 3.2GHz …

US comp-boffins claim fix for multicore 'concurrency bugs'

American computer boffins say they have developed new software which makes programming of multi-processor machines much easier. "With older, single-processor systems, computers behave exactly the same way as long as you give the same commands. Today's computers are non-deterministic," says Luis Ceze, computer science and …

Power7 v Power6 - it's all about the cache

IBM is launching the first of its Power7-based systems today, and the company thinks that the innovations inside the Power7 processor are going to give it a leg-up on the competition in terms of capacity, throughput, and energy-efficiency. But how do those Power7 processors stack up to the existing Power6 and Power6+ processors …

AMD cuts to the core with 'Bulldozer' Opterons

IT shops buy current products, but they always have their eyes out one or two generations to assure themselves they aren't buying into a dead-end product. Which is why makers of chips and other components that go into systems as well as system makers themselves are forced to talk about the future when what they really want to do …

Quanta opens servers to 100-core Tilera

Upstart multicore, Linux-compatible chip maker Tilera don't need no stinking tier one server makers. That means no IBM, Dell, Hewlett-Packard, or Sun Microsystems. At least not yet. The company has just lined up $25m in its C round of funding, which includes $10m from Quanta Computer, the Taiwanese PC maker that is the volume …

Tilera pushes to 100 cores with mesh processor

Upstart massively multicore chip designer Tilera has divulged the details on its upcoming third generation of Tile processors, which will sport from 16 to 100 cores on a single die. That will give Tilera bragging rights for cramming the most general purpose computing cores onto a die, although graphics chip makers are already …

Apple open sources Snow Leopard's multicore code helper

In a surprise move, Apple has open-sourced its Grand Central Dispatch (GCD) technology under the Apache 2.0 public license. Baked into the recently released Mac OS X 10.6, aka Snow Leopard, GCD eases the programming challenges that developers face when coding for multicore processors. You can download a PDF of Apple's half- …

The multicore future, and how to survive it

Multicore processors may offer a wealth of powers, but writing efficient code for them is notoriously difficult. Thankfully, help is close at hand. The Multicore Association created the Multicore Programming Practices (MPP) working group just over a year ago to produce a guide on best practices for writing multicore-ready …

Chip makers to flex their bits at Hot Chips

Next week, the IEEE's annual Hot Chips conference will be take place at California's Stanford University, and it looks like there's an eight-core ante for any microprocessor vendor who wants to make a presentation. On August 24, AMD kicks off Hot Chips 21 with a discussion on blade servers based on the future 12-core Magny- …

Microsoft puts Sun's Tremblay in SiArch

There are so many things that software giant Microsoft could do with a seasoned chip designer of the caliber of Marc Tremblay, it's a wonder Sun would ever let him get away in the first place. As we pointed out yesterday, not everything that Tremblay helped etch into silicon at Sun turned into gold. But plenty of the chips he …

Phone designers to improve reality

Multicore Expo Future phones will recognize buildings and people by sight and replace reality with something better. They'll also have roll-out HD displays. Or projectors. Or they'll dock with your PC's display. At least, that's the vision of some visual-computing visionaries at this week's Multicore Expo, inspired by the graphic and …
