Most of us take for granted the inner workings of a Google search and all we're concerned about is receiving near instantaneous results to our query. And just as well, because Google hasn't been one to pony up much specifics on the hardware it uses to sift through oodles of web pages. That is, until Google Fellow Jeff Dean gave a keynote talk at ESDM 2009.
According to Dean, a typical Google search might consume the processing power of 1000 machines. Talking about Google's growth in the past decade, Dean said search queries have gone up by x1000, and so too has the company's processing power (# machines * speed of the machines). In addition, Dean claims query latency has dropped from under 1000ms to normally under 200ms, as well as dropping the update latency by a staggering x10000, so that crawler updates have been reduced from several months down to just a few minutes.
Dean says the improved performance is a result of switching the holding indexes to now being completely in memory. The result is that it takes thousands of machines to process a search query, but it has made near instantaneous searches possible.
Ruh-roh, Shaggy, it looks as though SSDs might not be all that and a bag of chips after all. Or more specifically, Intel's mighty X25-M SSD may prove a better sprinter than a marathon runner.
One of the major concerns with SSD technology is that the cells are good only for a finite number of writes, at which point they become read-only. Intel address this potential problem using sector remapping and wear-leveling algorithms, but a new report shows it might carry a nasty performance-reducing side effect.
Most wear-leveling algorithms dynamically move frequently-rewritten logical sectors to different physical sectors of the drive, ensuring that no cells are written to more frequently than others. Intel takes it a step further by extending its remap table into individual sectors, which reduces the number of small block writes needed for small files. The problem, according to PCPerspective, is that Intel's method seriously degrades long-term performance. After two of the site's writers noticed that their X25-M SSDs were performing signicantly slower after a length of time, the review site reran the drives through its gamut of benchmarks and found the drives had indeed degraded in performance, and in some cases, reads were reduced to a paltry 22MB/s. Zoinks!
If you own an X25-M and find that your drive has also slowed down considerably, there are fixes in place. According to Intel, one way to restore performance is to use IOMeter to sequentially write content to the entire drive. PCPerspective said it met with limited success using this method, but had much better results using Intel's second suggestion, which is to use a tool to perform a SECURE ERASE command on the drive. Using an older version of HDDErase (v3.3), the site says it was able to restore its X25-M back to its original performance levels.

BenQ has finally made good on their promises to release an all-in-one computer, and it has come in the form of the nScreen i91.
The screen-based computer has a sizeable 18.5-inch 16:9 LCD screen, with an AMD Semperon 210U processor, 1GB of memory and a 160GB HDD under the hood. To help sweeten the deal they’ve included a 4-in-1 card reader, an integrated webcam, and an average power consumption of just 30 watts.
It’s designed to be as easy to use as possible, with a main selling point that you can simply plug it in, press the volume/power knob, and be on the Internet.
There haven’t been any announcements yet as to when this will be available here in the U.S., but it is currently available in Taiwan for roughly $517.
OCZ has added a backlit keyboard to its Alchemy line of gaming peripherals, but this one comes with a twist. Unlike traditional backlit planks, OCZ's Illuminati lets users switch between blue or red LED backlit keys, erasing the fear that the decor at the next LAN party you attend might clash with your keyboard.
In addition to the user-selectable color scheme, the Illuminati comes equipped with rubber-coated keys, which the company claims will last for more than 5 million cycles. Gamers can also make use of 14 multimedia and internet hotkeys and a curved wrist wrest. What you won't find on the keyboard are any USB ports.
OCZ launched its Alchemy line last year in an attempt to offer gaming peripherals without the high prices that typically come hand-in-hand. The Illuminati is the third keyboard in the company's Alchemy series, with the Elixir and Elixir II having come before it.
To borrow from Jerry Maguire's 'You had me at hello' scene, Maingear's newest product announcement had us 'Core i7,' but lost us when the talk turned to the GPU. The new Prelude 2, as it's being called, combines Intel's Core i7 platform with a Samsung 22-inch LCD monitor and tops it off with Nvidia's 3D Vision Technology, and at under two grand, it sounds like an intriguing proposition. But sticking out like a sore thumb is the inclusion of Nvidia's mid-range 9800GT videocard.
"The fact that Maingear customers will have the ability to play games in 3D stereo is just awesome," said Ujesh Desai, general manager of GPU business at NVIDIA. "NVIDIA GeForce 3D Vision is taking the world by storm, and Maingear’s Prelude 2 is going to deliver a mind-blowing experience."
That "mind-blowing experience" will be delivered by Intel's Core i7 920 (2.66GHz) processor nestled into an Asus P6T X58 motherboard, 3GB of triple channel DDR3-1066 memory, a 250GB Western Digital hard drive with 16MB of cache, onboard audio, a 650W power supply, and Windows Vista Home Premium 32-bit all stuffed inside a Lian-Li enclosure.
To be fair, this is only a baseline configuration. The Prelude 2 offers plenty of customization options, including up to a 1200W power supply, up to two of the hard to find dual-GPU GeForce GTX 295 videocards, Intel's full lineup of Core i7 processors, liquid cooling, up to 12GB of Corsair XMS DDR3-1333MHz memory, up to four hard drives (including Intel's X25-M 80GB SSD, Western Digital's Velociraptor, and RAID 0), and a host of other goodies.
The Prelude 2 is available now from Maingear.com starting at just shy of $2000 (baseline configuration).
Shuttle has always been good about their barebone systems, and that trend doesn’t stop with the SX58H7. This beefy little scrapper comes ready for tons of power, by the means of Intel’s Core i7 and two video cards.
The SX58H7 comes with an X58 Express chipset, and 500 watt PSU, two PCI-Express 2.0 x16 slots, space for up to 16GB of DDR3 DRAM, and room for two SATA II drives. Should you be looking to hook yourself into the lifeline of data, there’s also two gigabit Ethernet jacks on the back.
It’ll run you about $611, which isn’t a pleasant price tag. But, if you’ve got some money burning a hole in your pocket, and want to put a lot of power in a small place, be sure to check this out.
Sony has reached an agreement with Corel to use the latter’s InstantON technology in future Vaio P-series netbooks. Vaio Ps with Corel’s instant-on OS will begin appearing on American store shelves later this month. A lot of PC manufacturers are incorporating instant-on solutions in their netbooks.
The technology allows users to perform tasks like web browsing without having to wait for the main OS to boot. Though both the companies waxed eloquent about the inclusion of Corel’s Instant On technology in the world’s lightest 8 inch notebook, it still doesn’t seem enough to justify the netbook’s $900 price tag.
This is starting to get ugly. It's bad enough watching Intel and Nvidia go at each other over licensing disputes (remember how long we waited for SLI on Intel chipsets?), but the two aren't showing any signs of letting up. In response to Intel's recent lawsuit, which alleges Nvidia has no right to produce chipsets that are compatible with any Intel processor that has an integrated memory controller, the GPU/chipset maker had some choice words for Intel.
"We are confident that our license, as negotiated, applies," said Jen-Hsun Huang, president and CEO of Nvidia. "At the heart of this issue is that the CPU has run its course and the soul of the PC is shifting quickly to the GPU. This is clearly an attempt to stifle innovation to protect a decaying CPU business."
Huang has never been one to mince words, at one time declaring his company would "open a can of whoop-ass." Now less than a year later, the quote-worthy CEO has declared the CPU just another run-of-the-mill component taking a backseat to the GPU.
Nvidia's press release went on to talk up the company's Ion platform, and was quick to point out that it "offers 10x the performance of Intel's current three chip design." Huang also said that given the broad and growing adoption of Nvidia's platforms, including the Ion, he's not the least bit surprised Intel is disputing a four-year-old contract.
You know that couple that is always at odds with each other, turning parties and other get-togethers into awkward affairs? The worst part is when they both turn to you to pick a side, and all you're trying to do is have a good time. For power users, that couple is Intel and Nvidia. We don't know what it is with these two, but just when their relationship appears to be on an upswing, another squabble breaks out.
After years of butting heads, Intel and Nvidia just recently came to agreement over licensing the GPU maker's SLI technology for use on Intel chipsets, and all appeared to be right in the world. But now the two are at it again, this time with Intel taking the offensive. Intel has filed suit against Nvidia this week claiming that the four-year old chipset license agreement between the two does not cover both its current and any future CPUs with integrated memory controllers.
"Intel has filed suit against Nvidia seeking a declaratory judgment over rights associated with two agreements between the companies," Intel said in a statement. "The suit seeks to have the court declare that Nvidia is not licensed to produce chipsets that are compatible with any Intel processor that has integrated memory controller functionality, such as Intel’s Nehalem microprocessors and that Nvidia has breached the agreement with Intel by falsely claiming that it is licensed. Intel has been in discussions with Nvidia for more than a year attempting to resolve the matter but unfortunately we were unsuccessful. As a result Intel is asking the court to resolve this dispute."
Nvida contends that the license agreement is still valid, however admits that it has been "working with Intel to come to some kind of agreement" for the past year. And despite the lawsuit, Nvidia says it has no plans of changing its roadmap, including those chipsets which extend to future processors.
So you’re looking for a new gaming rig, but all those Mid-ATX beasties just aren’t what you’re looking for, huh? Direct your eyes to Shuttle’s new SDXi Carbon, a beautiful, power packed box with a price tag to match!
