SDXC UHS-I To Supports 4K Video Resolution

UHS speed Class 3 has been announced, which is a new high performance class that supports 4K video in its 4096 × 2160 (8.8-megapixel) resolution. The new class will be available for SDXC UHS-I and UHS-II and SDHC UHS-I and UHS-II memory cards and devices.

UHS speed class 3 defines a minimum of 30 Megabytes per second for high quality video and this should be enough even for large 4K video format files. The SD Association came up with UHS-I and UHS-II high performance bus interface that can support data transfer between SD memory card and device or up to 104 megabytes for UHS-I and 312 megabytes per second for UHS-II as a theoretical limit. Hoover, the actual speed will be much slower, but effective enough.

4K videos, live broadcasts and content can be recorded on high-performance devices such as Digital Single Lens Reflex (D-SLR) cameras, Digital Single Lens Mirrorless (D-SLM) cameras, camcorders and video cameras and then played back smoothly. New devices offering the UHS Speed Class 3 will be backwards compatible and will work with existing SD memory cards.

The compatibility of UHS Speed class 3 cards with existing devices, but at lower speeds, is unsure at the moment. There has been a lot of talks about the SDXC cards working on some unsupported devices, however the odds are that they will not work unless specifically stated. More about speed/benefits can be found here and information about compatibility can be found here.

NVIDIA Tesla GPUs and Intel Xeon Phi Coprocessors seen in Cray XC30 Supercomputers

Cray Inc. today announced the Company has expanded its support for accelerators and coprocessors. Cray is now selling the XC30 series of supercomputers with NVIDIA Tesla K20X GPU accelerators and Intel Xeon Phi coprocessors. Cray’s Adaptive Supercomputing vision has reached its goal today, which is focusing on delivering innovative systems that integrate diverse technologies like multi-core and many-core processing into a unified architecture.

“We designed the Cray XC30 supercomputer to be the realization of our Adaptive Supercomputing vision, which is about providing customers with a powerful, flexible tool for solving a multidisciplinary array of computing challenges,” said Cray’s senior vice president of high performance computing systems, Peg Williams. “Integrating diverse accelerator and coprocessor technologies into our XC30 systems gives our customers a variety of processing options for their demanding computational needs. Equally as important, Cray XC30 supercomputers feature an innovative software environment that allows our customers to optimize their use of diverse processing options for their unique applications.”

The Cray XC30 bear the code-name “Cascade” and are Cray’s most advanced HPC systems supercomputers which were engineered to meet the performance challenges of today’s HPC users. The Cray XC30 and Cray XC30-AC supercomputers feature the unique Aries system interconnect, a Dragonfly network topology that frees applications from locality constraints, innovative cooling systems to lower customers’ total cost of ownership, the next-generation of the scalable, high performance Cray Linux Environment supporting a wide range of ISV applications, Cray’s HPC optimized programming environment, and the ability to handle a wide variety of processor types.

“The Intel Xeon Phi coprocessor is designed for high-density computing and highly parallel processing while offering important efficiencies in programmability for the software developer community,” said Rajeeb Hazra, Intel Vice President & General Manager, Technical Computing Group. “The performance and programmability of Intel Xeon Phi coprocessors, along with the Intel Xeon processors, will enable a powerful and energy-efficient Cray XC30 supercomputer that will be broadly applicable for scientists, engineers, and researchers in achieving their breakthrough innovations.”
