An Open Source Compiler From CUDA To X86-Multicore 71

Posted by timothy from the abstraction-gains-a-layer dept.
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."

Revisiting the "Holy Trinity" of MMORPG Classes 362

Posted by Soulskill from the or-druid-as-the-case-may-be dept.
A feature at Gamasutra examines one of the foundations of many MMORPGs — the idea that class roles within such a game fall into three basic categories: tank, healer, and damage dealer. The article evaluates the pros and cons of such an arrangement and takes a look at some alternatives. "Eliminating specialized roles means that we do away with boxing a class into a single role. Without Tanks, each class would have features that would help them participate in and survive many different encounters like heavy armor, strong avoidance, or some class or magical abilities that allow them to disengage from direct combat. Without specialized DPS, all classes should be able to do damage in order to defeat enemies. Some classes might specialize in damage type, like area of effect (AoE) damage; others might be able to exploit enemy weaknesses, and some might just be good at swinging a sharpened bit of metal in the right direction at a rapid rate. This design isn't just about having each class able to fill any trinity role. MMO combat would feel more dynamic in this system. Every player would have to react to combat events and defend against attacks."

NY Court Says Police Can't Track Suspect With GPS 414

Posted by kdawson from the when-a-cop-slaps-you-on-the-back-check-your-back dept.
SoundGuyNoise sends in a story that brings into relief just how unsettled is the question of whether police can use GPS to track suspects without a warrant. Just a couple of days ago a Wisconsin appeals court ruled that such tracking is OK; and today an appeals court in New York reached the opposite conclusion. "It was wrong for a police investigator to slap a GPS tracking device under a defendant's van to track his movements, the state's top court ruled today. A sharply divided NY Court of Appeals, in a 4-3 decision, reversed the burglary conviction of defendant Scott Weaver, 41, of Watervliet. Four years ago, State Police tracked Weaver over 65 days in connection with the burglary investigation."

Depressed Astronauts Might Get Computerized Solace 138

Posted by CmdrTaco from the just-email-them-porn dept.
alphadogg writes "Clinical tests on a four-year, $1.74 million project for NASA, called the Virtual Space Station, are expected to begin in the Boston area by next month. The effort is designed to address the onset of depression in astronauts while they are in outer space. In the project, sponsored by the National Space Biomedical Research Institute, a recorded video therapist guides astronauts through a widely used depression therapy called 'problem-solving treatment.'" Here's a related story from a few weeks ago. Those astronauts got it rough.

Flower Robots For Your Home 119

Posted by timothy from the pretty-high-on-maslow's-hierarchy dept.
Roland Piquepaille writes "Flower robots are not new, and some have already been developed in the US. Now, South Korean researchers have created a robotic plant which acts like real ones. This robot has humidifying, oxygen-producing, aroma-emitting, and kinetic functions. It is about 1.30 meters tall and 40 centimeters in diameter. The robotic plant can interact with people when they approach, and it can 'dance' when music is played. The researchers don't say when a commercial version of their flowers will come to the market. They also don't mention a retail price."

Google Demands Higher Chip Temps From Intel 287

Posted by CmdrTaco from the because-they-can dept.
JagsLive writes "When purchasing server processors directly from Intel, Google has insisted on a guarantee that the chips can operate at temperatures five degrees centigrade higher than their standard qualification, according to a former Google employee. This allowed the search giant to maintain higher temperatures within its data centers, the ex-employee says, and save millions of dollars each year in cooling costs."
