Supercomputers at Oak Ridge National Laboratory produce some of the world’s largest scientific datasets, many of which are related to climate change research. In this interview, Galen Shipman, data-systems architect for ORNL’s Computing and Computational Sciences Directorate and the person who oversees data management at the OLCF, discusses strategies for coping with the “3 Vs” of big data: variety, velocity, and volume.

Multicore chipmaker Adapteva is sampling its 4th-generation multicore processor, known as Epiphany-IV. The 64-core chip delivers a peak performance of 100 gigaflops and draws just two watts of power, yielding a stunning 50 gigaflops/watt. The engineering samples were manufactured by GLOBALFOUNDRIES on its latest 28nm process technology.

Solid state storage specialist Nimbus Data Systems has unveiled its third-generation flash memory array, setting new benchmarks on resiliency, performance, and capacity. The new product, known as Gemini, offers up to 48 TB of capacity and over 1 million IOPS per 2U box. And despite moving to the less expensive and less reliable consumer-grade MLC flash, Nimbus has managed to double the endurance of its storage arrays.

In a recent report in Real World Technologies, chip guru David Kanter dissects the new 64-bit ARM design and what it might mean to the IT landscape. His take on the architecture is almost uniformly positive, noting that not only did the designers manage to develop an elegant instruction set that was backwardly compatible with the existing ISA, but they also took the extra step to jettison a few of the poorly designed features of the 32-bit architecture.
