The supercomputing biz seems to have shaken off most of the after-effects of the global recession, with scads of new deployments large and small around the world. China, in particular, continued its big push into HPC, notching its first home-grown super. And Japan ushered in the era of 10-petaflop supercomputing this year with its world-beating K Computer. But, as always, not all the HPC news was rosy. Here are the top hits and misses for the year.

The leap forward in genomics technology promises to change health care as we know it. Sequencing a human genome, which costs millions of dollars just a few years ago, now costs thousands. And the prospect of mapping a genome for under a thousand dollars is on the horizon.

As has become apparent to nearly everyone in the HPC community, life beyond petascale supercomputing will be power limited. Many efforts around the world are now underway to address this problem, both by commercial interests and researchers. One such effort that brings both into play is the Mont-Blanc research project at the Barcelona Supercomputing Center (BSC), which is looking to exploit ARM processors, GPUs, and other off-the-shelf technologies to produce radically energy-efficient supercomputers.

CUDA introduces developers to a number of new concepts (such as kernels, streams, warps and explicitly multi-level memory) that are not encountered in serial or other parallel programming paradigms. In addition, CUDA is frequently used alongside MPI parallelism and host-side multi-core and multi-thread parallelism. The TotalView parallel debugger provides developers with methods to handle these CUDA-specific constructs, as well as an integrated view of all three levels of parallelism within a single debugging session.

Oak Ridge National Laboratory has awarded a contract to Cray Inc. to increase the Jaguar supercomputer's science impact and energy efficiency. The upgrade, which will provide advanced capabilities in modeling and simulation, will transform the DOE Office of Science-supported Cray XT5 system, currently capable of 2.3 million billion calculations per second (petaflops), into a Cray XK6 system with a peak speed between 10 and 20 petaflops.

Financial services firms are examining every aspect of their infrastructures to squeeze any delays out of their end-to-end computational workflows. This quest to lower latencies in each step of processing trades, and to perform other chores, was a common theme at the High Performance Computing Financial Markets Conference held in New York, last week.

NVIDIA started shipping Tesla M2075 GPU computing modules. It is optimized for power and performance as a successor to Tesla M2070. With Tesla M2075, customers can take advantage of 10% lower power for the same performance as its predecessor. In addition, M2075 improves ECC reporting. Applications that use a lot of cuFFT will see a performance improvement. Solutions based on Tesla M2075 are available from all leading OEMs.

Computational scientists at the Pittsburgh Supercomputing Center (PSC) and HP Labs have achieved speedups of nearly 10 times with GPUs (graphic processing units) versus CPU-only code (and more than 1000 times versus an implementation in a high-level language) in k-means clustering, a critical operation for data analysis and machine learning.
