Apple's new OS geared for multicore future

Apple began shipping Snow Leopard on Friday, but the true importance of the Mac OS X update likely will emerge well afterward.

That's because Mac OS X 10.6 begins a longer-term Apple attempt to get ahead by cracking a problem facing the entire computer industry: squeezing useful work out of modern processors. Instead of stuffing Snow Leopard with immediately obvious new features, Apple is trying to adjust to the new reality in which processors can do many jobs simultaneously rather than one job fast.

"We're trying to set a foundation for the future," said Wiley Hodges, director of Mac OS X marketing.

Apple shed some light on its project, called Grand Central Dispatch, at its Worldwide Developer Conference in June, but most real detail was shared only in with programmers sworn to secrecy. Now the company has begun talking more publicly about it and other deeper projects to take advantage of graphics chips and Intel's 64-bit processors.

The moves align Apple better with changes in computing. For years, chipmakers such as Intel and Advanced Micro Devices had steadily increased the clock rate of their processors, and programmers got accustomed to a performance boost with each new generation. But earlier this decade, problems derailed the gigahertz train. … Read more

Intel, Microsoft event to highlight Windows 7 improvements

Intel and Microsoft will hold an event next week to discuss collaboration on improvements to Windows 7.

The event, on September 1 in San Francisco, will "share how the two companies collaborated on key enhancements during the development of Windows 7," according to Intel. Steve Smith, vice president and director, Intel's Digital Enterprise Group Operations, and Michael Angiulo, general manager of Windows Planning and PC Ecosystem at Microsoft, will talk at the event. Microsoft plans to launch Windows 7 on October 22.

Windows 7 collaboration will be demonstrated by engineers from both companies, according to Intel. Not … Read more

Intel acquires two software firms

Intel has quietly snapped up two software companies in the last 30 days with aim of boosting development of applications that take better advantage of chips with more than one processing core.

In a company blog, the chipmaker indicated the acquisition of Cilk at the end of last month and then Rapidmind earlier this week. Both are small companies that employ under 50 people. The acquisitions follow the purchase of software company Wind River Systems in June.

"Over the last few years, there has been a gradual emergence of multicore microprocessors. It's put parallelism in more and more … Read more

Windows 7 will give boost to PC hardware

Windows 7 will be more than just a better interface. Under-the-hood changes will allow chips from Intel, Nvidia, and Advanced Micro Devices to ratchet up Windows 7 performance above previous Microsoft operating systems.

Microsoft on Wednesday said it has finalized the code for Windows 7, set to ship with new PCs starting October 22. Improvements will include how Windows handles multitasking, graphics acceleration, and solid-state drives.

Microsoft is working closely with Intel, whose chips will power the vast majority of PCs running Windows 7. A July 22 post from Intel's Joakim Lialias, Alliance Manager responsible for Microsoft, described how … Read more

Adobe: why Lightroom image export isn't faster

Updated 3:04 p.m. PDT with further Adobe remarks. I misunderstood the company's position: Lightroom's export behavior reflects engineering priorities.

Earlier this month, I encountered an Adobe Photoshop Lightroom analysis by consultant Lloyd Chambers that expressed surprise with a facet of the image editing and cataloging software: it didn't export photos as fast as possible.

Chambers found that if a photographer wants to produce JPEG or TIF images from the originals in the program, the fastest way is to divide the batch into thirds and export each third separately. Using a modern Mac Pro system, exporting a test set of photos took 351 seconds as one batch and 189 seconds divided into three batches running at the same time.

"The big disappointment is the sluggish performance importing and exporting files, which are tasks that are key to efficient workflow--tasks one has to do over and over. Most of the 'juice' of a Mac Pro goes untapped," Chambers concluded. "You have to load it up with more than one job to force more of the available CPU cores to be used. Lightroom should do this automatically!"

The study caught the attention of others, including Scott Kelby, head of the National Association of Photoshop Professionals. I was intrigued, too, because although many programming chores are difficult to spread across multiple processor cores, exporting photos is trivially easy since it breaks conveniently into independent bite-sized pieces. So I thought I'd see what Adobe had to say for itself. … Read more

Apple: Next Mac OS X unlocks chip power

This story was corrected. See below for details.

SAN FRANCISCO--Apple wants Mac OS X to do a better job dealing with the new directions that Moore's Law has taken computer chips.

At its Apple Worldwide Developer Conference here, Bertrand Serlet, senior vice president of software engineering, shed light on technology called Grand Central Dispatch that's designed to make Mac OS X 10.6, called Snow Leopard, take better advantage of multicore processors and graphics processors.

Computer chips for years improved in performance through faster clock speeds, but processor engineers ran into problems with chips consuming inordinate amounts of … Read more

Intel: Use our CPU (not their GPU) for games

Intel is back, pitching its processors for gaming graphics.

The chipmaker will attempt to promote its silicon for sophisticated game effects at the upcoming Game Developers Conference in March, as it strives to make a case for quad-core processors in lieu of graphics chips from Nvidia and Advanced Micro Devices.

The pitch goes like this: "Learn how to easily add real-time 3D smoke, fog and other fluid simulations to your game without using up the GPU." That's according to an Intel Web page entitled Intel at Game Developers Conference. (The CPU is the central processing unit, or … Read more

Gartner: Multicore chips leave software trailing

Gartner sounded a warning on Wednesday about the impact on software of the rapid growth of multicore chips and the number of threads each processor can handle.

In a research note, the analysts argued that software is struggling to keep pace with the fast growth of multicore processors, first from two and four cores per processor, and now to eight and even 32 cores in high-end servers. With 32 processors per socket already shipping, four years from now machines could host 1,024 processors, Gartner said.

Analyst Carl Claunch said: "Many of the software configurations in use today will … Read more

Supercomputing wrap-up

At some point during the flight over the Pacific from Tokyo, I seriously questioned my decision to take a detour rather than heading straight to Boston and home. It wasn't that I had no interest in attending the Supercomputing show, SC08, being held in Austin last week. It's just that I was coming off of what was already a two-week trip to Japan. However, Supercomputing has been getting more and more buzz in recent years--and I hadn't been able to attend previously because of conflicts--so duty beckoned.

I was glad I made it. It was an immensely … Read more

Buzz Out Loud 844: Number one in space junk, USA!
