An Open Source Compiler From CUDA To X86-Multicore 71

Gregory Diamos writes "An open source project, Ocelot, has recently released a just-in-time compiler for CUDA, allowing the same programs to be run on NVIDIA GPUs or x86 CPUs and providing an alternative to OpenCL. A description of the compiler was recently posted on the NVIDIA forums. The compiler works by translating GPU instructions to LLVM and then generating native code for any LLVM target. It has been validated against over 100 CUDA applications. All of the code is available under the New BSD license."

Comment Re:engineers vs. scientists (Score 1) 338

Your idea of the LHC commissioning being in the hands of typical investigative scientists is incorrect. In the area of particle physics there are two big sets of expertise: theoretical physicists and experimental physicists. It is the EPs that design and build the components of the LHC and they have plenty of engineering expertise.

EA Shuts Down Pandemic Studios, Cuts 200 Jobs 161

lbalbalba writes "Electronic Arts is shutting down its Westwood-based game developer Pandemic Studios just two years after acquiring it, putting nearly 200 people out of work. 'The struggling video game publisher informed employees Tuesday morning that it was closing the studio as part of a recently announced plan to eliminate 1,500 jobs, or 16% of its global workforce. Pandemic has about 220 employees, but an EA spokesman said that a core team, estimated by two people close to the studio to be about 25, will be integrated into the publisher's other Los Angeles studio, in Playa Vista.' An ex-developer for Pandemic attributed the studio's struggles to poor decisions from the management."

Professor Layton and the Curious Twitter Accounts 26

Ssquared22 writes "'Frankly ... I'm ashamed. I have made myself a Twitter page and officially joined the world of technology. Perhaps Luke may help me update.' With those words on June 28, 2009, what had been just a fictional character in a Nintendo DS game became a fixture on Twitter. Over the coming days and weeks, the TopHatProfessor account would post dozens of riddles and brainteasers of the type found in 2008's Professor Layton and the Curious Village and the upcoming Professor Layton and the Diabolical Box, soliciting answers from his slowly growing cadre of followers. Along the way, the professor happily answered questions about the upcoming title and shared little slices of life from his day, all without ever breaking character. Many followers were bemused and intrigued by what they assumed was a clever new viral marketing campaign put on by Nintendo ahead of Diabolical Box's August release. In reality, though, the TopHatProfessor account was the work of a lone college student and amateur game journalist, trying to get attention for a game he felt was being sorely neglected by publisher Nintendo and the media at large."

Some of their ethernet switches block non-IE browsers as well. I forget which is which, but I think the PowerConnect 6000s warn about the browser but let you through, and the 5000s just refuse to let you in when running firefox on linux.
My experience is from a few years ago and perhaps they have fixed their firmware since then, I know I filed a complaint.

Ask Jazz Technical Lead Dr. Erich Gamma 83

As IBM continues to build out Jazz, their community-oriented development site, technical lead Dr. Erich Gamma has offered to answer questions about Jazz or anything else in his realm of expertise. Among his many accomplishments, Erich worked with Kent Beck on the Java unit testing framework, JUnit, and was actively involved until JUnit 4. Dr. Gamma was also one of the fathers of Eclipse and the original lead on the Eclipse Java development tools. Feel free to fire away on Eclipse, Java, JUnit, the Rational suite, the Jazz site, or anything else you think Erich might be able to answer. Usual Slashdot interview rules apply. Update 19:05 GMT by SM: As pointed out by user Hop-Frog, Dr. Gamma is also co-author of the influential computer science textbook Design Patterns: Elements of Reusable Object-Oriented Software.

Iran Tries To Pacify Protesters With Lord of The Rings Marathon Screenshot-sm 419

Iranian state television's Channel Two is playing a Lord of the Rings marathon in an attempt to keep people inside watching hobbits and not protesting in the streets. Normally, people in Tehran are treated to one or two Hollywood movies a week, but with recent events the government hopes that sitting through a nine-hour trilogy will take the fight out of most of the protesters. Perhaps this was not the best choice in films if you want your people not to believe that "even the smallest person can change the course of the future."

Directory Service Implementation From Scratch? 149

An anonymous reader writes "I work at a small but growing startup company. Currently, our directory and authentication information is scattered across many systems and wikis, and is becoming increasingly difficult to manage. We are looking at centralizing this information in a directory service to minimize administrative overhead as we continue to grow. The service must support basic directory searches, as well as user authentication for Linux and Windows hosts. Although we are primarily a Linux shop, there are a handful of Windows systems that will be on a Windows Active Directory domain. Most directory servers seem to support integration with other directory servers, however it seems like it may be easiest to just use Active Directory for everything. Are there any pitfalls with this approach? If you had the chance to redesign your enterprise directory service without regard for legacy services, how would you do it?"

The Myth of the Mathematics Gender Gap 588

Coryoth writes "The widely held belief that there is disparity in the innate mathematical abilities of men and women has been steadily whittled down in recent years. The gender gap in basic mathematics skills closed some time ago, and recently the gap in high school mathematics has closed up as well, with as many girls as boys now taking high school calculus. Newsweek reports on a new study published in The Proceedings of the National Academy of Sciences that begins to lay to rest the remaining argument that it is at the highest levels of mathematics that the innate differences show. Certainly men dominate current academia, with 70% of mathematics Ph.D.s going to men; however that figure is down from 95% in the 1950s. Indeed, while there remain gaps in achievement between the genders, the study shows that not only are these gaps closing, but the size of the gap varies over differing cultures and correlates with the general degree of gender inequality in the culture (as defined by World Economic Forum measures). In all, this amounts to strong evidence that the differences in outcomes in mathematics between the genders is driven by sociocultural factors rather than innate differences in ability."

Submission + - The Homeless Stay Wired

theodp writes: "San Franciscan Charles Pitts has accounts on Facebook, MySpace and Twitter. He runs a Yahoo forum, reads news online and keeps in touch with friends via email. Nothing unusual, right? Except Pitts has been homeless for two years and manages this digital lifestyle from his residence under a highway bridge. Thanks to cheap computers, free Internet access and sheer determination, the WSJ reports that being homeless isn't stopping some from staying wired. 'You don't need a TV. You don't need a radio. You don't even need a newspaper,' says Pitts. 'But you need the Internet.'"
