Too many developers limit themselves to C++ and Java, in spite of the wealth of exciting new options
Today’s computer science graduate often leaves school with a strong knowledge of only one programming language — typically a major systems language, such as Java or C++ — and goes on to a career based almost exclusively on [...]

As multicore processors are becoming commonplace, machine-vision software vendors are re-engineering their products, allowing their customers to leverage the power of multiprocessing. However, the task is not trivial since the programmer must optimize the power of image-processing functions across multiple processors. While the maximum expected performance increase of multiprocessing can be predicted to some extent [...]

Andras Vajda writes about his experience while he was on a panel last week at the DATE (Design, Automation and Test in Europe) conference, debating programming MPSoC systems. In this post, he discusses a question: “When will we get rid of C and replace it with something better?”
“The question itself brought back to attention the [...]

“Many software developers have since been hard at work optimizing their applications to take advantage of multiple cores. Single-core CPUs are actually hard to find and two-, three-, and four-core CPUS are now the norm.
Which begs the question: how many CPU cores are right for me? Is a triple-core [...]

Cilk Arts’ Charles Leiserson talks about the key issues facing software developers going multicore. To that end, they conducted over 70 in-depth interviews with customer prospects. Over the course of the interviews, they heard a triad of key themes repeatedly:
1. Development time
2. Software reliability
3. Application performance

When [...]

In response to a recent post, less focus on threads and more focus on tasks, Gastón C. Hillar writes that he agrees that decomposing the job to be done into many tasks is the key to a successfully parallelized algorithm.
Once you have the most important tasks, you can re-design the algorithm taking into account [...]

Here is a video of the first public demonstration of OpenCL running on a GPU was done by NVIDIA on December 12, 2008 at SIGGraph Asia. This demo of OpenCL on NVIDIA GPU was based on early non-released OpenCL API/driver interface. The nbody simulation shown was a simulation of massive particles under the influence of [...]

Murphi is a popular finite-state machine verification tool, used widely in the design of cache coherence algorithms and protocols, link-level protocols, executable memory model analysis, and analysis of cryptographic and security-related protocols. These complex protocols are often verified by examining all reachable protocol states from a set of possible start states. With proper memory management [...]

AMD celebrates its 40 year anniversary next month, and the Athlon brand turns ten shortly thereafter. What better way to celebrate than by releasing a rebadged 65nm Phenom processor with two cores disabled at $69?
It’s called the Athlon X2 7850 and it actually has very little in common with the old Athlon 64 X2s. [...]
