GreenLight project will study energy efficiency of real-time computing

 

The US National Science Foundation has provided US$2 million in funding for the GreenLight project at UC San Diego (UCSD). The project’s goal is to make computing processes more energy efficient by using photonics—light over optical fiber. As part of the project, researchers will measure energy consumption and output using sensors and make the data available to researchers in real time. The project will use Sun Modular Datacenter S20s, which can house up to 280 servers in an environmentally friendly design that uses closed-loop water-cooling systems to reduce cooling costs by up to 40 percent compared to traditional server rooms. GreenLight’s data center will provide computing and storage services to projects in metagenomics, ocean observing, microscopy, bioinformatics, and digital media. Some of the research groups participating in the project will relocate servers to the data center and work virtually over UCSD’s high-performance network. (Science Daily)

Google upgrades search appliance

 

In September, Google plans to begin shipping the Search Appliance GB-7007, an updated search box that can index up to 10 million documents. The Search Appliance is a hardware box loaded with search software that lets enterprises index and retrieve data across their corporate data infrastructures. The GB-7007 builds on the GB-1001, which has a maximum indexing load of 3 million documents. The GB-7007 can’t be clustered, so Google will still produce the GB-1001, which can be clustered in configurations of five or eight units to provide indexing capabilities for up to 10 million or 30 million documents respectively. The GB-7007 also lets IT administrators tailor search results based on user types—employees in accounting will receive different results than those in marketing when searching on similar terms. Additionally, the GB-7007 natively supports the Kerberos authentication protocol. (Techworld)

IBM releases open source software for supercomputers

 

At the LinuxWorld Conference and Expo in San Francisco, IBM released the HPC Open Software Stack, software designed to facilitate the deployment of supercomputer clusters. Included in the software are the Extreme Cluster Administration Toolkit (xCAT), developed for large clusters using IBM’s Power architecture, and Advance Toolchain for Power Systems 1.1, a resource management tool.  HPC Open Software supports Red Hat Enterprise Linux 5.2 and IBM Power6 processors.  The National Center for Supercomputing Applications at the University of Illinois is hosting the software for download from its repository.

Comcast must stop P2P throttling

 

The US Federal Communications Commission (FCC) has ordered Comcast to stop throttling P2P traffic on its networks. Comcast must comply with the FCC’s request by the end of this year. Press reports in 2007 revealed Comcast’s networking throttling—which was conducted without notifying subscribers. In a statement, FCC chairman Kevin Martin  likened Comcast’s actions to the post office screening mail and withholding delivery. “Would you be OK with the post office … if they opened letters mailed to you, decided that because the mail truck is full sometimes, letters to you could wait, and then hid both that they read your letters and delayed them? Unfortunately, that is exactly what Comcast was doing with their subscribers’ Internet traffic.” If Comcast fails to comply with the FCC’s order, it faces an injunction and penalties.

Researchers to demonstrate login information hack at Black Hat

 

Security researchers have developed a technique that could let attackers steal usernames and passwords from Web sites. The technique involves a hybrid file—what they call a Gifar (a combination of a GIF file and a Java Archive file)—that looks different to different programs or applications viewing it. Web servers will view the file as a GIF image whereas browsers will open it as a Java Archive file and run it as an applet. Web sites that let users upload their own images, such as Facebook and MySpace, are particularly vulnerable. Attackers could create a phony Facebook account, for example, and upload Gifar images containing malicious code. The browsers of victims lured into viewing the phony profiles would run the Gifar as an Java applet, giving attackers access to login information. However, the attack requires victims to be logged in. The researchers plan to demonstrate the attack at the upcoming Black Hat conference. (Techworld)

IEEE approves faster FireWire specification

 

The IEEE has approved IEEE 1394-2008, a FireWire specification that will allow for bandwidth up to 3.2 Gbps.  The specification will also support the S1600 specification (1.6 Gbps) and will be backwards compatible with the S400 and S800 specifications (400 Mbps and 800 Mbps respectively). The IEEE says the specification will be available in October. In contrast, USB 2.0, a FireWire’s competitor, reaches top speeds of 480 Mbps. The next version of USB (3.0) will have a rate of 4.8 Gbps but is scheduled for release in 2010. (ZDNet UK)

IBM develops tool that scans code as it’s written and flags errors

 

The Rational Software unit of IBM has developed the Rational Software Analyzer, a tool that flags errors as programmers write their code. The tool is similar to Microsoft Word’s spelling and grammar checker. It flags problematic code and lets programmers click on help boxes that include suggestions for fixing the code as well as sample code. Programmers can configure the tool to flag known security weaknesses too. Developer and enterprise editions are available now. (Computerworld)

HP, Intel, and Yahoo team up for cloud computing testbed

 

Hewlett-Packard, Intel, and Yahoo have joined together to form the Cloud Computing Test Bed, a research environment aimed at open source collaboration. The companies will also join forces with US universities, the Karlsruhe Institute of Technology in Germany, and Singapore’s Infocomm Development Authority to set up six data facilities to research cloud computing. The data centers will be equipped with HP hardware using Intel processors. The machines will run open source software including Apache Hadoop and Pig, a programming language that Yahoo’s research unit developed. The group plans to have the centers up by the end of the year, at which time it plans to invite more universities and companies to participate. (Computerworld)

India plans $10 laptop for students

 

At the e-India 2008 digital learning conference in New Delhi, India’s Minister of State for Higher Education, D. Purandeswai, said the country hopes to provide school children with US$10 laptops. The Indian Institute of Sciences in Bangalore and the Indian Institute of Technology are researching the government-sponsored initiative. Along with the laptops, the government plans to provide free bandwidth for education purposes. (PC World)

Oracle issues security alert for WebLogic server

 

A vulnerability in the Apache plug-in for Oracle’s WebLogic Server and Express products has prompted the company to issue a security alert while it works to create a patch. The vulnerability could lead to attackers “compromising the confidentiality, integrity and availability of the target system,” the company wrote in a blog posting. Attackers can launch the exploit over a network without usernames or passwords, the advisory said. The flaw is severe enough to score a 10.0—the most serious rating—on the Common Vulnerability Scoring System. Oracle advises network administrators to use its recommended workaround until a patch is released. (Computerworld)
