NASA Launches Remote Real-Time Visualization Demo at SC09

MOUNTAIN VIEW, Calif., Nov. 12 -- Engineers at NASA Ames Research Center (ARC) in Mountain View, Calif., are driving remote simulation visualizations at 20 Gbits/s directly from the Columbia supercomputer by extending the machine's InfiniBand fabric to the SC09 show floor in Portland, Ore., using Obsidian Longbow E100 devices.

"NASA's high-end computing users are distributed across the country," said Alan Powers, HPC technical director of CSC at the NASA Advanced Supercomputer (NAS) facility at Ames, "so it is highly advantageous to be able to share access to supercomputing resources and provide secure high speed data transfers -- including remote real-time visualization -- without compromising fidelity or security."

Obsidian's Dr. David Southwell observes, "Remote visualization applications are very demanding on the network, being bandwidth intensive and sensitive to latency, loss, arrival time jitter and quality of service. NASA's InfiniBand-based supercomputers interface naturally to Obsidian's Longbow E100 products, which transparently extend InfiniBand over 10 GbEthernet WAN connections in a manner that preserves all of InfiniBand's properties (such as determinism and lossless flow control) while simultaneously applying standards-based AES-192-GCM cryptography."

In the demonstration, a pair of 10 Gb Ethernet circuits are used to carry 20 Gbits/s of visualization traffic from supercomputers in Mountain View to a multi-paneled display wall in Portland, while the data and assets at either end of the link are protected by the Longbow E100's authentication and encryption functions, which operate at full line rate.

Live demonstrations of real-time visualization driven from NASA supercomputers in Mountain View, Calif., can be viewed in NASA's booth, #1947.

About Obsidian Strategics

Obsidian Strategics is the developer of Longbow, a series of InfiniBand products featuring range extension, routing and encryption. Longbow technology allows an InfiniBand fabric, normally a short-range network used in high-performance computing, to be extended via optical fiber over varying distances. Longbow connects across Campus, Metro or Global networks to offer unparalleled high-bandwidth, low-latency access to InfiniBand compute and storage resources.

NVIDIA Works On CPU Co-Dependency Issues with Kepler GPU

NVIDIA is telling everyone that the GK110, its new Kepler GPU aimed at supercomputing, is all about improving performance per watt. But the other driving theme behind the new architecture is reducing the GPU's reliance on its CPU host. How well it accomplishes both these goals areas could determine the success of the new chip in high performance computing.
