RSC Group, a four-year-old maker of clusters based in Moscow that has created some of the most energy efficient machines installed in Russia, got plenty of attention last week at SC13 with its new PetaStream system. Like many top-end systems created today, the PetaStream is a hybrid design, and in this case it mixes a Read more…
It’s been nearly a year since the Intel Xeon Phi Coprocessor debuted at SC12, and in that time, it has experienced strong acceptance from the community. But as this is a relatively new technology, research into its usefulness is still forthcoming. Adding to the growing body of research on the Phi is “Understanding the Costs Read more…
Not content to let the Tianhe-2 announcement ride alone, Intel rolled out a series of announcements around its Knights Corner and Xeon Phi products–all of which are aimed at adding some options and variety for a wider base of potential users across the HPC spectrum. Today at the International Supercomputing Conference, the company’s Raj….
The mainstream adoption of accelerator-based computing in HPC is driving the most significant change to software since the arrival of MPI almost twenty years ago. Faced with competing “similar but different” approaches to heterogeneous computing, developers and computational scientists need to tackle their software challenges quickly. They are rapidly discovering that a single unified development toolkit able to both debug and profile is the key to results – whichever platform they choose.
Traditional HPC languages, Fortran, C and C++, have little native control over hardware capabilities such as SIMD operations, multi-core availability and prefetch instructions. The burden of optimization is therefore…
Despite developer hassle, this is a great problem from the perspective of companies who are finding ways to tailor clean layers around complex code for heterogeneous computing. Take, for example, Atlanta-based AccelerEyes, which is seeing booming business because of the demand for GPU acceleration and interest in kicking the Xeon Phi co-processor tires.
How does the Phi coprocessor measure up to Xeon “Sandy Bridge” brand-mate?

It’s a coup – for Atipa, CPU accelerators and Xeon Phi.
Intel’s manycore wonder comes with its own programming challenges.
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Xeon_Phi_chip_small.jpg” alt=”” width=”96″ height=”79″ />With the recent introduction of Intel’s first Xeon Phi coprocessors, NVIDIA’s latest Kepler GPUs, and AMD’s new FirePro S10000 graphics cards, the competition for HPC chip componentry has entered a new phase. The three chipmakers have taken somewhat different paths, though, and it will be up to the market to decide which vendor’s approach will win the day.
