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.

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?"

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.'"

Core bit I think you are missing is that it takes a lot of energy to cool all the necessary parts down to near absolute zero (I believe I read somewhere that it takes a couple weeks to do the initial chill at least). I imagine the cost to keep it running (with or w/o ongoing injections) is less due to the initialization sequence, as it were.

Comment Eclipse (Score 5, Informative) 1055

I like Eclipse as an IDE because it supports many languages/modes and is very customizable. I mostly use it for Java, Perl and HTML/XML/CSS right now. There are MANY plugins and the context-aware help/auto-complete is very well done.
