Quantum rewrites the rules of computing

Quantum computing holds huge promise, and scientists say it could eventually surpass classic supercomputers for tackling enormous calculations, like cryptography and finding planets. But there's debate over whether quantum computers truly exist. Google and NASA are testing one.

Faster computer performance targeted by memory consortium

Faster memory is a focal point in the race to boost application performance, and an industry consortium aims to make computers zippy with a new specification released on Tuesday.

IBM's new business unit aims to make Watson a moneymaker

IBM continues to commercialize its Watson-branded cognitive computing technology, setting up a new Watson business unit and unveiling two new Watson-derived services.

Thanks to the NSA, quantum computing may some day be in the cloud

The NSA is spending some $80 million in basic research on quantum computing, money that may ultimately help commercialize quantum computing for the private sector.

D-Wave pitches quantum co-acceleration to supercomputing set

Controversial quantum device maker D-Wave is hoping to find a home for its cutting-edge technology in the high-performance computing (HPC) market.

Why the U.S. may lose the race to exascale

In the global race to build the next generation of supercomputers -- exascale -- there is no guarantee the U.S. will finish first.

SC13: Elevation plays a role in memory error rates

With memory, as with real estate, location matters. A group of researchers from Advanced Micro Devices and the Los Alamos National Laboratory have found that the altitude at which SRAM (static random access memory) resides can influence how many random errors the memory produces.

SC13: GPUs would make terrific network monitors

A network researcher at the U.S. Department of Energy's Fermi National Accelerator Laboratory has found a potential new use for graphics processing units -- capturing data about network traffic in real time.

Top500 shows growing inequality in supercomputing power

Supercomputing power is being concentrated in a smaller number of machines, according to the latest Top500 list of high-performance computers. Keepers of the list are uncertain how to parse that trend.

Cray brings Hadoop to supercomputing

Helping scientific supercomputing take advantage of emerging big-data technologies, high-performance computing manufacturer Cray is releasing a set of packages promising to optimize the process of running Hadoop on the its XC30 machines.

Dell simplifies the blade server

Dell's PowerEdge C6220 squeezes four two-socket servers into 2RU, delivering blade server density at a rack-mount price. Insider (registration required)

IT's most wanted: Mainframe programmers

As students study other technologies, vendors try to develop new talent and offer tools to fill the gap for these critical systems

Silver Surfers are past it? Never!

Been around a while? You may well be a "Silver surfer" and that makes you an IT hero!

A New Job for Mainframes?

Mainframes are stable, secure and could be perfect for anchoring a private cloud. But where's the user provisioning?

New job for mainframes: Cloud platform

As companies take steps to develop private clouds, mainframes are looking more and more like good places to house consolidated and virtualized servers. Their biggest drawback? User provisioning is weak.

You don't know tech: InfoWorld news quiz

Feb. 18, 2011: iPhones may get smaller, security firm gets unwelcome caller

The clock is ticking on encryption

The strength of today's communications security is based on the complexity of our encryption algorithms. But the day is coming when cracking those algorithms may be computationally trivial.

How China Will Eat the U.S.'s Tech Lunch

Is Congress really ready to make the U.S the world's No. 2 supercomputing power?

Disruptors have lasting impact on IT

Major market shifts in the database world don't happen often. When they do, they're massive, creating an impact that can last 10 to 20 years. When I entered the job market, it was right at the tail end of the last major shift from the mainframe to client/server.

QuickPoll: Should the U.S. be worried about China's supercomputing plans?

The Department of Energy says China is 12 to 18 months away from building an "entirely indigenous" supercomputer. Should the U.S. be worried?
