HP announces plans to add solid state memory to servers

 

At the HP Technology Forum & Expo 2008 in Las Vegas, HP and Fusion-io announced a collaboration that will allow Fusion-io’s flash-based drives to connect to HP servers’ PCI express slots and increase storage capacity up to 640 GB per card. HP’s current line of servers have up to 10 PCI slots each. Fusion-io has plans to increase the storage capacity of its drives to 1.28 TB in 2009, said David Flynn, the company’s chief technology officer. Pricing and availability have yet to be determined.

Most powerful supercomputers revealed at the International Supercomputing Conference

 

The world’s five most powerful supercomputers are housed in the US, according to a list presented at the International Supercomputing Conference in Dresden, Germany. The Roadrunner, which broke the petaflop barrier earlier in the week, takes the top spot. Rounding out the top five are the BlueGene/L at the Lawrence Livermore National Laboratory, the IBM BlueGene/P at the Argonne National Laboratory, the Sun SunBlade x6420 at the University of Texas, Austin, and the Cray XT4 at the Oak Ridge National Laboratory. Europe has 184 of the top 500, while Asia houses 48 supercomputers. (Network World, 06/18/08)

New algorithm identifies location of Flickr photos

 

Carnegie Mellon University researchers will present IM2GPS, an algorithm that analyzes the composition of photos to identify where they were taken, at the IEEE Computer Society Conference on Computer Vision and Pattern Recognition on 24–26 June in Anchorage, Alaska. The algorithm scans photos for composition, textures, and color and records the number of lines and their orientation. It then searches Flickr for photos with similar characteristics. The researchers say the algorithm could be used in forensic investigations or in tandem with geographic databases to measure climate, population, and land use. (Science Daily, 06/18/08)

New Search Technology Center based in Europe in the works for Microsoft

Microsoft announced it will create a Search Technology Center in Europe on Tuesday. The company has yet to decide on a location for the center, but it’s aiming for a 30 June 2009 opening date. Microsoft said the European center will be modeled on the Search Technology Center in Beijing and place its engineers in various countries across Europe. The new center will work with the company’s global Live Search team to increase its long-term investments, Microsoft said. (Information Week, 06/17/08)

Amsterdam launches first mobile Wimax network in Europe

On Tuesday, Dutch telecom Worldmax launched the first mobile Wimax network in Europe, giving its users high-speed Internet access on the go. Worldmax’s network covers only the city of Amsterdam for now, but the company hopes to extend the network across the country by adding roughly 3,000 access points at a cost that is expected to run into the hundreds of millions of dollars. The company said access will cost roughly US$31 (20 euros) per month and require no long-term contract. (Reuters, 06/17/08)

US bill requires 911 network operators to allow VoIP providers access

 

The US Senate unanimously passed the New and Emerging Technologies 911 Improvement Act on Monday. The act requires operators of 911 networks to let voice over IP providers connect to their networks at the same rates and conditions as mobile phone companies. In addition, the bill offers 911 networks liability protection when handling VoIP calls and requires the US government to establish a plan for developing next-generation 911 capabilities.

Nvidia introduces new high-performance GPU

Nvidia announced its new graphics processing unit, the Tesla 10P, as the successor to its Tesla 8 GPU for high-performance computing. The Tesla 10P boasts one teraflop of computational power and 4 GBs of RAM, double that of the Tesla 8 GPU. The added power gives companies additional options, Nvidia says. Instead of adding dual- or quad-core processors to servers or workstations, companies can add the new GPU, which offers 10 times the computational power while using the same amount of energy, according to Nvidia. Coding algorithms for Tesla GPUs requires developers to use Nvidia’s compute unified device architecture. Nvidia is offering the GPU in two form factors: the Tesla S1070, which fits in standard 19-inch servers, and the Tesla C1060, which is a card that fits into workstations’ PCI Express slots.

Phoenix processor uses less power than current chips on the market

Researchers at the University of Michigan will present the Phoenix processor, a microchip that uses roughly 30,000 times less power in sleep mode and 10 times less power in active mode than current chips, at the upcoming IEEE Symposium on VLSI Circuits in Honolulu, Hawaii. The chip’s intended use includes sensor-based devices such as implants or surveillance equipment, but could also be extended to environmental monitoring for air or water networks. The chip’s size is one square millimeter, equal to the size of many chips already on the market. The innovation, however, is that the chip’s low power consumption has allowed the researchers to reduce the battery size. The whole system, including the battery, is projected to be roughly 1,000 times smaller than current sensing systems. (Science Daily, 06/16/08)

Microsoft launches new OS for personal navigation devices

On Monday, Microsoft released Windows Embedded NavReady 2009, its first OS for personal navigation devices (PNDs). The OS includes Bluetooth support, which will let PND manufacturers build devices that can connect to online services such as Microsoft’s Live Search and map service, mobile phones, and computers using Windows. In a statement, Kevin Dallas, general manager of Microsoft’s embedded business for Windows, said the early release will let manufacturers adopt the Embedded NavReady OS for upcoming devices in time for the upcoming holiday season.

New compression technique leaves VoIP open to eavesdropping

A research team from Johns Hopkins University has developed software that can eavesdrop on encrypted voice-over-IP streams that use a new compression by measuring the packet size of words and phrases. The compression technique—called variable bitrate compression—varies the size of data packet. Longer and more  complex sounds have higher sampling rates while shorter and simpler sounds have lower sampling rates. The new technique cuts down on the bandwidth needed but maintains sound quality. However, the researchers created software that can partially decode VoIP conversations using software that searches for certain words and phrases and compares them to sample conversations in a database. When the software finds a match, it alerts the eavesdropper. The software yielded a 50 percent accuracy rate on short phrases; the percentage rose to 90 percent on longer and more complex words.
