I was particularly impressed at how fast CUDA has gained traction in HPC and other areas. The CUDA wave has definitely hit the beach and I’ll have more on nVidia as the Fermi GPU begins to filter into the HPC trenches. In this column I want to talk about the other GPU [...]

The introduction of multicore processors in a slew of battery-powered devices is an interesting development. The ARM processor now comes in quad-core configurations, and the Intel Atom processor is now shipping in a dual-core configurations.
We can only assume there will be more cores at each new process node, and probably more cores added [...]

The addition of multiple cores inside of computers has created an enormous opportunity for virtualization. Instead of running one operating system or one application, a single server or multicore PC can run multiple virtualized OSes on a single machine at the same time.
From the standpoint of energy efficiency, this has been a huge [...]

Think about any mobile Internet device today. Batteries typically last all day, applications shut down with ease, and the number of things it can do has reached the point where many people typically carry one device on the road rather than multiple devices they used to lug around several years ago.
Perhaps even more [...]

Edward Richards, a Senior Field Applications Engineer for Green Hills Software, had a confession to make at the Real Time Embedded Computing Conference (RTECC) held in Santa Clara recently. No matter the processor architecture in use, he had no more single-core customers in Silicon Valley. All of his clients had moved to multicore [...]

Intel will release its fastest and highly anticipated eight-core Nehalem-EX server processor later this month, a company executive said late Thursday.
The processor will be targeted at four-socket servers, said Shannon Poulin, Xeon platform director at Intel. Each physical core will be able to run two threads simultaneously, giving the chip 64 virtual processing [...]

At UBM TechInsights, we’re often tasked with proving patent infringement of a software algorithm as part of our IP Management Services. An embedded algorithm can range from a sensoring technique in an appliance, to motor control, to power management scheme, to navigation algorithm, to UI control or file system on a higher end embedded device; [...]

Application developers for software on mobile phones and other embedded devices can achieve acceptable performance levels ten times faster thanks to a breakthrough by European researchers.
Human-readable software code needs to be translated into binary code by a compiler if it is to run on hardware. When hardware is upgraded the software’s compiler usually needs to [...]

Memory sub-system components contribute significantly to the performance characteristics of an application. As an increasing number of threads or processes share the limited resources of cache capacity and memory bandwidth, the scalability of a threaded application can become constrained. Memory-intensive threaded applications can suffer from memory bandwidth saturation as more threads are introduced. In such [...]

“Fast immutable persistent functional queues for concurrency with Groovy” talks about implementation of functional queues with Groovy++. Here is another article to use these queues to implement several algorithms for processing of asynchronious messages. You can find source code and more examples in the Groovy++ distro.
This article discusses implementing simplified actor, the object [...]

We all know that OpenMP is a well-known, widely accepted programming model for parallel programming on shared-memory platforms. It is based on so-called OpenMP directives that programmers add to their code to inform the compiler about which fragments of the program can be executed in parallel. Most of OpenMP is designed to allow [...]

Most companies, when they go to the enormous expense of designing a complex chip, tell everyone about it. Even a company like Sun or IBM, whose chips are used only in their own computers, unveil the details of their new processors well before products based on those new parts come to [...]
