Last month, Intel brought us out to the Texas Advanced Computing Center (TACC) in Austin to brief us on its latest and greatest foray into high-performance computing (HPC) and exascale level processing performance. For Intel, years of heady talk about parallelism and exascale computing have finally come to fruition. Intel is bringing to market a pair of Xeon Phi coprocessor offerings in 2013, the 3100 family and the 5110p, and we’ve got the full scoop for you here... Intel’s Exascale HPC Revolution and Xeon Phi...

Last month, Intel brought us out to the Texas Advanced Computing Center (TACC) in Austin to brief us on their latest and greatest foray into high-performance computing (HPC) and exascale level processing performance. Parallel Computing and the Road to Exascale There are mountains of problems that need to be solved and a myriad of insight to be gained, in fields from the sciences to national security, that require HPC and highly parallel processing to most effectively and efficiently solve. Parallel processing is what the HPC space is all about, and when large amounts of data can be processed and complex problems solved, it can help researchers move from the concept phase to the...

The second day of the AMD Fusion Developer Summit began with a keynote from Microsoft’s Herb Sutter, Principal Architect, Native Languages and resident C++ guru. The gist of Herb’s talk centered around heterogeneous computing and the changes coming with future versions of Visual Studio and C++. One of the main highlights of the talk was a demo of a C++ AMP application that seamlessly took advantage of all of the compute resources within a few of the various demo systems, from workstations to netbooks. The application seamlessly switched from using CPU, integrated GPU, and discrete GPU resources, showcasing the performance capabilities of each. Heterogeneous computing capabilities...

A key Microsoft kernel architect, David Probert, has come out with a surprising statement regarding Windows' ability to harness multiple cores. While Windows has taken advantage of multicore technology for over a decade, Probert notes that users rarely see the performance that they should. "Why should you ever, with all this parallel hardware, ever be waiting for your computer?" Probert asked in a presentation last week at the Universal Parallel Computing Research Center in Champaign-Urbana. Each successive OS release from Microsoft has improved multicore scaling but bottlenecks regularly occur as multiple applications jockey for position. Priority scheduling helps a certain amount, but it's...

The programmer's Pandora's Box has been opened, and boy oh boy is it full of cores. It started out small and manageable with Intel's popular Core 2 and the Athlon 64, but it's getting out of hand quickly with chips with dozens and dozens of cores on the horizon now. The problem is that all that firepower is going to go to waste because nobody knows how to program software to take advantage of it. Wired took a good look at the challenges facing the multicore software programmer, and the chipmakers who want to love them. Typical 9-to-5 programmers, who are used to programming single-thread apps, are ill-equipped to handle things such as memory locks or calculation delays. What's more,...
