Intel Turbo Boost Technology 2.0

Intel has optimized Intel Turbo Boost Technology1 to provide even more performance when needed on 2nd Generation Intel Core processor based systems. Intel Turbo Boost Technology 2.0 automatically allows processor cores to run faster than the base operating frequency if it's operating below power, current, and temperature specification limits.


Dynamically increasing performance:

Intel Turbo Boost Technology 2.0 is activated when the Operating System (OS) requests the highest processor performance state (P0).

The maximum frequency of Intel Turbo Boost Technology 2.0 is dependent on the number of active cores. The amount of time the processor spends in the Intel Turbo Boost Technology 2.0 state depends on the workload and operating environment.

Any of the following can set the upper limit of Intel Turbo Boost Technology 2.0 on a given workload:

Number of active cores

Estimated current consumption

Estimated power consumption

Processor temperature

When the processor is operating below these limits and the user's workload demands additional performance, the processor frequency will dynamically increase until the upper limit of frequency is reached.

Intel Turbo Boost Technology 2.0 has multiple algorithms operating in parallel to manage current, power, and temperature to maximize performance and energy efficiency.

Sticky Bit: Intel Turbo Boost Technology 2.0 allows the processor to operate at a power level that is higher than its rated upper power limit (TDP) for short durations to maximize performance.

Another Try by Google to Take On Facebook

Google has tried several times, without much success, to take on Facebook and master social networking. Now it is making its biggest effort yet.

Google introduced a social networking service called The Google+ On Tuesday(30-06-11).Which happens to look a lot like Facebook. The service, which is initially available to a select group of Google users who will soon be able to invite others, will let people share and discuss status updates, photos and links, much as they do on Facebook.

But the Google+ project will be different in one significant way, which Google hopes will be enough to convince people to use yet another social network.

It is meant for sharing with groups, Like colleagues, roommates or hiking friends — not with all of one's friends or the entire Web. It also offers group text messaging and video chat.

In social networking, Google finds itself in an unusual position, one that its competitors in Web search know all too well: playing catch-up with a service that dominates the market.

The debut of Google+ will test whether Google can overcome its past stumbles in this area and deal with one of the most pressing challenges facing the company. At stake is Google's status as the most popular entry point to the Web. When people post on Facebook, which is mostly off-limits to search engines, Google loses valuable information that could benefit its Web search, advertising and other products.

But Google+ may already be too late. In May, 180 million people visited Google sites, including You Tube, compared with 157.2 million on Facebook, according to comScore. But Facebook users looked at 103 billion pages and spent an average of 375 minutes on the site, while Google users viewed 46.3 billion pages and spent 231 minutes.

Advertisers pay close attention to those numbers — and to the fact that people increasingly turn to Facebook and other social sites like Twitter to ask questions they used to ask Google, like a recommendation for a restaurant or doctor.

Analysts say that Facebook users are unlikely to duplicate their network of friends on Google+ and post to both sites, but that they could use them for different types of communication. Google+ could also attract Facebook holdouts who have been uncomfortable sharing too publicly.

Handling Threads in quad core processor

This depends on the exact processor line and model.

Intel's Core i7, i5, and i3 series can handle 2 threads per core, so any quad-core model could handle 8 threads.

AMD's Athon, Phenom, Sempron, and Opteron chips, on the other hand, are designed around a 1-thread-per-core model.

At the other extreme end, are the SPARC Niagara series of server chips, which can handled anywhere from 8 to 16 threads per core.


All this isn't free. Thread count per core comes at a cost - the more threads per core, the lower performance each individual thread has. That is, using the same hardware, if I run one thread on a core, that thread will run faster than 2 similar threads, even if the threads are independent.

Facebook veterans in venture capital spotlight

As Wall Street eagerly awaits signs that Internet sensation Facebook will offer shares to the public, the venture capitalists
that prowl California's Silicon Valley are keeping close tabs on another hot commodity: the employees leaving Facebook.

A handful of start-up companies founded by Facebook alumni are attracting attention and generating a good amount of buzz within venture circles, where competition is fierce to get a stake in the web's next hit product. On Monday, Quora, a start-up founded by four ex-Facebook employees, including former Chief Technology Officer Adam D'Angelo, raised a Series A round of funding from Benchmark Capital that the technology blog TechCrunch said valued the company at $86 million, citing an unnamed source.

Benchmark partner and former Facebook product management vice president Matt Cohler will sit on Quora's board. Quora, which operates out of a small, college-dorm-like suite in downtown Palo Alto, California, with cardboard crates of water-bottles stacked waist-high against the walls, had not planned to raise money so early, said D'Angelo, who is the CEO of Quora. "We weren't really shopping it around, but there was a lot of interest" from VCs, he said in a phone interview with Reuters after the announcement of the funding on Monday.

The company was started in April 2009, and the product which was launched in January 2010, can currently be used only by people who have received a special invitation. D'Angelo declined to comment on the financial terms of the deal, but said the funding will help Quora hire more staff and focus on a wider set of technical challenges underlying the product - an online question and answer service based on people's social connections.

The proliferation of start-ups with Facebook veterans, and the investor interest in them, follows a time-tested Silicon Valley pattern in which tech superstars from Google Inc to Fairchild Semiconductor have spawned innovative start-up companies, said Nick Sturiale, a general partner at JAFCO Ventures. "Any enterpreneur spinning out of Facebook is going to get attention," said Sturiale. "They're at the vanguard of how the Web is emerging."

Facebook, which counts 400 million active users and is the world's No.1 Internet social network, has yet to announce any plans for an initial public offering -- the traditional payday that allows early company insiders to cash-out and move on to new projects.

But the active secondary market for Facebook shares -- including more than $100 million in officially-sanctioned stock purchases of employee shares by Facebook investor Digital Sky Technologies last year -- has allowed Facebook employees to decamp at an earlier stage, say some VCs. "We've seen loads of people leave Google and now we're seeing loads of people leave Facebook.

Either because they're vested, or because they think the company's gotten too big," said Spark Capital's Todd Dagres. Dagres said he's looking at several startups founded by ex-Facebook employees, but he notes that a Facebook connection is not enough. "You definitely pay attention if somebody is leaving Google or Facebook. But then you've got to make sure that they really have built a track record, that they didn't just work there," said Dagres. A number of Facebook-related start-ups have already passed muster.

Asana, whose founders include Facebook co-founder Dustin Moskovitz, raised $9 million in December from Benchmark Capital and Andreessen-Horowitz. Cloudera, which features former Facebook, Google, Yahoo Inc and Oracle Corp veterans on its management team, raised $11 million from Greylock Partners and Accel Partners in two separate rounds of funding last year. Meanwhile, Path, a secretive project led by former Facebook employee Dave Morin and Shawn Fanning, the creator of music sharing service Napster, has piqued a lot of interest in tech circles though it's unclear if the company is looking to raise money.

Some entrepreneurs, like former Facebook director of international business development Net Jacobsson, say there's no overwhelming pressure to raise capital right away, thanks to the low cost with which Web start-ups can be created these days. Jacobsson, who advised social gaming firm Crowdstar after leaving Facebook in May 2009, recently set up his own social game start-up dubbed PlayHopper.

The game development is primarily taking place in China, he said, and the goal is to generate revenue as soon as the first game is released. Several VC firms have contacted him to check-in on his new project and in some cases to inquire about investing in the company, said Jacobsson, who noted that he was still thinking over whether he needed to take money from outside investors
