Exascale computing: it's the new terascale

Filed under: Desktops

Anybody remember when a gigaflop was a big deal? Oh, how far we've come. Researchers are now talking about exascale computing, which means systems that can handle a million trillion calculations per second. To put that in perspective, IBM's BlueGene/L (pictured), the fastest machine running, has a peak performance of 596 teraflops. A petaflop is 1000 times faster than a teraflop, and an exaflop is 1000 times faster than a petaflop. Yeah, that's a lot of flops. Right now researchers are sorting out the most preliminary of groundwork, such as how do you get data to tens of thousands of processors at a time for crunching, but we're sure before a few decades are up they'll finally have built a machine that is powerful enough to cure all human diseases -- or, you know, maybe even play Crysis at 60fps.

MetaRam aims to bump RAM capacity by 4x overnight

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/240712957/

Filed under: Desktops

We're not sure what whacky voodoo snakeoil these MetaRam people are peddling, but the company's got some high profile behind it (like Intel, for one), is being led by former AMD CTO Fred Weber, has appears to have some potentially revolutionary RAM quadrupling technology. Claiming to have leapfrogged current RAM technology by 2-4 years, MetaRam uses a specialized "MetaSDRAM" chipset that effectively bonds and addresses four cheap 1Gb DRAM chips as one, tricking any machine's memory controller into using it as a 4x capacity DIMM. Since a 1Gb chip is apparently far less expensive than a 2Gb chip, MetaRam devices can multiply capacity at prices far lower than their competition; the company claims it'll be shipping in machines in the first quarter of this year, and Hynix has already announced their own 2-rank 8GB DDR2 RDIMMs for the second half.

Fujitsu MHZ2 BT: the latest 500GB 2.5-inch laptop drive

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/240733784/

Filed under: Laptops, Storage

Solid state is still what gets our motors purring, but 500GB of storage in your laptop isn't anything to scoff at, either. Fujitsu's new MHZ2 BT is the second drive to hit the half-terabyte mark, but just like the Hitachi 500 gigger it's a non-standard height (12.5mm), meaning you won't be able to slap it in most laptops or enclosures -- unless you're willing to shave out an extra ~3mm of surrounding matter. Expect 'em out in May.

Click Fraud Keeps Rising, Up 15 percent in 2007

Source: http://feeds.feedburner.com/~r/Techcrunch/~3/239496869/

Click Forensics has some data out on click fraud (clicks on Internet ads that are not real) in the fourth quarter of 2007 and for the full year. The industry-wide average click fraud rate for the entire year went up 15 percent, ending the year with 16.6 percent of all clicks on Web ads being fraudulent. The click fraud rate for search engine ad networks alone, including Google AdSense and Yahoo Publisher Network, grew even more. That was up 47 percent in the fourth quarter, ending the year with a 28.3 percent click fraud rate. According to this data, nearly one out of every three clicks on a Google or Yahoo ad is fraudulent.

While the year-over-year growth is cause for concern, the click fraud rates remained pretty steady compared to the third quarter of 2007, when the overall click fraud rate was 16.2 percent and the search-engine click fraud rate was 28.1 percent (see charts above). One quarter does not make a trend, but could the click fraud rate be leveling off? One can hope. If Google can ever get that rate to actually go down, maybe its stock will shoot up again.

Click Forensics also published the handy heat map below showing the countries where the most click fraud is originating. (Red is bad, green is benign). The biggest sources of click fraud are India (4.3 percent), Germany (3.9 percent), and South Korea (3.7 percent). Mexico is also in the red.

Facebook Fatigue? Visitors Level Off In the U.S.

Source: http://feeds.feedburner.com/~r/Techcrunch/~3/239540820/

The number of people who visit Facebook has been leveling off over the past few months in the U.S., and even dipped by about 800,000 individuals in January. According to the latest stats from comScore, Facebook attracted 33.9 million unique visitors in January, 2008, down 2 percent from 34.7 million in December, 2007. Maybe all that friend spam has something to do with the decline. Will the Facebook fatigue get worse, or is this just a temporary dip?

Worldwide, Facebook is still doing fine. It grew 3 percent in January over December, attracting 100.7 million unique visitors. (MySpace had 109.3 million visitors worldwide, up 2 percent month-over-month. And in the U.S., it was slightly down as well from 68.9 million visitors in December, 2007 to 68.6 million in January, 2008. Despite its larger size, though, MySpace lost fewer visitors in the U.S. than Facebook did).
