IBM launches Power7 chip, systems
Monday, February 8, 2010
IBM on Monday is launching its long-anticipated Power7 processor and systems based on the chip.
The processor is a big step for IBM, integrating eight processing cores in one chip package, with each core capable of executing four tasks--called "threads"--turning an individual chip into a virtual 32-core processor. As a yardstick, Intel's high-end Xeon processors--systems that Power7 will compete with--typically have two threads per processing core.

Blg Blue has already tipped its hand on the Power7 chip in discussions about its upcoming Blue Water supercomputer.

Power7 fuses the flagship Power chip design with key technology from a separate "Cell" processor--the latter was part of IBM's Roadrunner supercomputer system at the Los Alamos National Laboratory. "We took some of that genetic material from the Cell program--ways to do floating point (calculations)--and embedded that right into the Power7 core," Bradley McCredie, an IBM Fellow in the Systems and Technology Group, told CNET last year.

Rivals include Hewlett-Packard servers based on Intel processors and servers from Sun Microsystems.

New Power7 systems

The new Power7 systems include:

  • IBM Power 780: a new category of scalable, high-end servers, featuring an advanced modular design with up to 64 Power7 cores.
  • IBM Power 770: a midrange system with up to 64 Power7 cores, featuring higher performance per core than Power6 processors and using up to 70 percent less energy for the same number of cores as Power6 processors.
  • IBM Power 755: a high-performance computing cluster node with 32 Power7 cores.

IBM is touting the Power7's ability to manage millions of transactions in real time--necessary for applications such as smart electrical grids. IBM said electric utilities can move from processing less than one million meter reads per day, in a traditional grid for example, to more than 85 million reads per day in a smart grid.

eMeter, a leading maker of software that runs e-grids, ran a successful benchmark on IBM Power6 systems for more than 20 million smart meters. "Combining eMeter and IBM's Power7 we are confident we can hit much higher numbers to meet their needs," Scott Smith, eMeter client business manager, said in a statement.

Facebook Launches New Look for its 6th Year
Facebook is celebrating its sixth anniversary with another redesign of its homepage.

Employees at Facebook last night were celebrating the company's anniversary, passing the 400 million user mark and the launch of yet another home page makeover.

The redesign is the latest of several home page changes launched by the company in recent years -- many times to the consernation of its users. The latest makeover, according to Jing Chen, a Facebook engineer, is focused improving navigation to the many features on the site.

"We think sharing information about the applications you use enriches the shared experience between you and your friends," said Chen in a Facebook blog post . "We hope the simplified design of the home page will make it easy for you to stay connected with the people, applications and activities that matter the most to you."

For example, the updated home page provides alerts about messages, notifications and requests. And the menu on the left-hand side of the page has added links to messages, events, photos and applications. If you click on "friends", a list of friend suggestions pops up, along with friend search options. Click on "applications" and you can see what Facebook apps your friends have been using.

Comments about the redesign posted beneath Chen's blog entry show that many users aren't so happy with the changes.

"New look is AWFUL!!!!! Please change back to old look and leave it alone," wrote one user. "Once more Facebook makes changes that don't work without doing proper testing," posted another.

While most of the comments on the site were negative, some users were happy about the changes. Wrote one user: "I love the new home page! It's great and I love the ease of access for the inbox etc."

With this makeover, Facebook also is trying to deal with complaints uttered after the last redesign about about privacy controls. Some Facebook users had complained loudly last fall that the redesign made it harder for them to maintain their own privacy settings.

The latest redesign looks to rectify that issue, Chen said.

"We feel strongly that control is an important element of any information sharing on Facebook," wrote Chen. "That's why these features are launching with an entirely new privacy setting. If you would rather not have your recent application activity visible in the dashboards to your friends, you can change this through your Privacy settings. We're also working on a more granular set of controls for specific applications, so that you can turn off activity for certain applications while leaving it on for others. We'll have more information to share on this soon."
