Solarflare has announced the expansion of its SFN5000 family of 10GbE server adapters with the launch of several new midrange 10GbE adapters. The Solarflare SFC9000 controller LAN-on-motherboard (LOM), announced in August 2009, enables the product's low-power, hardware-assisted virtualization and aggressive cost performance ratios.

The SFC9000 is the industry's lowest power controller and the industry's first LOM with integrated 10GBASE-T. With its hardware-assisted support for virtualization, the SFC9000 delivers up to 5 times the application performance of other server adapters by accelerating virtual I/O for Citrix XenServer, Microsoft Hyper V and VMware. The SFC9000 also possesses the industry's most scalable virtualization architecture, supporting up to 256 virtual functions and up to 2048 virtual NICs, 16 times greater scalability than conventional approaches.

The company's two new dual-port and single-port midrange 10GbE server adapters complement the currently shipping enterprise 10GbE server adapters, expanding Solarflare's footprint in the market, while offering customers better performance at more aggressive cost and performance points.

Midrange 10GbE server adapters

Solarflare's midrange dual-port and single-port 10GbE adapters deliver high-performance, low latency, low power and scalable I/O virtualization, offering exceptional value for datacenters, enterprise networks, virtualization and cloud applications, and high performance compute (HPC) clusters: SFN5162F Dual-Port 10GbE SFP+ Server Adapter, SFN5161T Dual-Port 10GBASE-T Server Adapter, SFN5152F Single-Port SFP+ Server Adapter, and the SFN5151T Single-Port 10GBASE-T Server Adapter.

"Our customers are very excited about our expanded 10GbE server adapter portfolio," Russell Stern, CEO of Solarflare. "Our midrange server adapters offer customers exceptional value. The power, performance and cost advantages are all possible because we were the first company with a 10GBASE-T LOM chip and have the lowest power PHY and the lowest power controller. We have the right feature set to enable high-frequency trading, high-performance computing for select verticals, such as scientific computing, oil, gas and manufacturing, as well as server virtualization for cloud networking."

Solarflare is the first and only company shipping both low-power, sub 5-watt 10GBASE-T transceivers and integrated, single monolithic 10GBASE-T LOM chips. Because Solarflare is the only company with the lowest power 10GBASE-T LOM, it is able to bring to market the lowest-power, single port 10GBASE-T adapter, at 7.9 watts, and the lowest power dual port 10GBASE-T adapter, at 12.9 watts, versus competing solutions at 20 watts or more. When a datacenter customer deploys 1000s of servers, the power savings add up to a quarter of a million kw/hours per year (2000 servers * 2 slots*7 watts*24 hours*365 days).

Solarflare 10GbE network adapters, often in combination with Solarflare OpenOnload application acceleration middleware, enable companies in a wide range of industries to build high-performance compute (HPC) clusters and datacenters that meet the most demanding computing and networking challenges. These include financial services, virtualized datacenters, energy, oil and gas and academic computing environments.

To date, Solarflare has shipped the SFN5122F 10GbE dual port SFP+ adapter to over 100 customers and 150 locations in China, Europe, US, India, Hong Kong and Singapore. The SFN5122F, with its OpenOnload application acceleration middleware, is also installed in every major equities exchange worldwide.

Molecular worm algorithm navigates inside chemical labyrinth

With the passage of a molecule through the labyrinth of a chemical system being so critical to catalysis and other important chemical processes, supercomputer simulations are frequently used to model potential molecule/labyrinth interactions. In the past, such simulations have been expensive and time-consuming to carry out, but now researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new algorithm that should make future simulations easier and faster to supercompute, and yield much more accurate results.

"Currently the major limiting factor in running molecular simulations for a large number of structures before they can be screened for useful materials is the need to visually analyze the structures to set up successful simulations," says Maciej Haranczyk, a computational chemist and a 2008 Glenn T. Seaborg Fellow in Berkeley Lab's Computational Research Division. "With our approach, such structural analysis can be done automatically, which speeds up the whole process of material screening."James Sethian (seated) and Maciej Haranczyk, of the Mathematics Group in Berkeley Lab's Computational Research Division, have developed a molecular worm algorithm that makes it easier and faster to simulate the passage of a molecule through the labyrinth of a chemical system.

Haranczyk is co-author of a paper that appears in the Proceedings of the National Academy of Sciences entitled: "Navigating molecular worms inside chemical labyrinths." The other author of this paper is James Sethian, who heads the Mathematics Group of Berkeley Lab's Computational Research Division, and is also a professor in the Mathematics Department of the University of California, Berkeley.

A key to the success of this new algorithm was its departure from the traditional treatment of molecules as hard spheres with fixed radii. Instead, Haranczyk and Sethian constructed "molecular worms" from blocks connected by flexible links. These molecular worms provide a more realistic depiction of a molecule's geometry, thereby providing a more accurate picture of how that molecule will navigate through a given chemical labyrinth, as Sethian explains.

"In practice, most molecules of interest, even the simplest solvents or gases, rarely have a spherical shape, and treating molecules as such may lead to errors," he says. "Our molecular worms are able to change shape during the traversing of a chemical labyrinth, which allows them to reach areas not accessible to either a single large spherical probe or a rigid real-shape probe. This significantly extends the range of probes and structures that can be efficiently examined."

As a molecule navigates through a chemical system, its access to a particular site or place within that system determines the extent to which catalysis and other chemical reactions may occur. Many of these critical sites are either buried in clefts, pockets or hidden cavities, or else represent channel systems. The accessible volume of a chemical system – the free volume available to a penetrating molecule - is also critical to the system's physical properties, including diffusion, viscosity and electrical conductivity. Predicting whether a molecule will be able to traverse through a given chemical labyrinth is the first question that a simulation must answer, followed by identifying the shortest transverse route, finding the largest probe that can transverse though the system, and calculating accessible volume.

This figure shows a molecular worm representing a butane molecule as it navigates through the chemical labyrinth of a typical alkane-cracking zeolite. The alogorithm was used to compute the shortest...

"The required calculations become quite expensive as one needs to include interactions of all the atoms of the penetrating molecule with all the atoms in the labyrinth, and this procedure has to be repeated at every step of the simulation," Haranczyk says. "Additionally, in molecular dynamics only one trajectory per molecule is investigated. Since a penetrating molecule can be bouncing off the walls of a system before it finds a way out, mapping accessible volume in a chemical labyrinth may require the running of a very long simulation to actually see the molecule moving through."

Haranczyk, looking to automate the process by which the void spaces of porous materials are analyzed, had an idea for a probe that would walk through the inside a material and map it. Sethian had been working on mathematic techniques that can be used in robotic navigations and path planning, as well as a host of algorithms for computing geometries in complex settings.

"What's exciting here is to bring together two disparate worlds to build a new technology" says Sethian. The two scientists pooled their expertise to develop the molecular worm algorithm, which they first tested on a zeolite material. Zeolites are microporous minerals that have been widely used since the late 1950s as chemical catalysts, membranes for separations, and water softeners. They are especially useful as alkane-cracking catalysts in oil refinement.

"There are 190 zeolite structures known to exist today, but they constitute only a very small fraction of the 2.5 million structures that are feasible on theoretical grounds," Haranczyk says. "The development of a database of hypothetical zeolite structures has long been regarded as an important step toward designer catalysts as it could, in principle, be screened for zeolites of any property. However, brute-force screening of all possible zeolite structures through molecular dynamics characterization is computationally infeasible, hence the need for rapid triaging based on an initial analysis of various properties."

The successful testing of the molecular worm algorithm on a typical alkane-cracking zeolite opens an immediate door to its use in screening for new zeolites as well as a wide variety of other porous materials. The algorithm should also prove valuable in the search for materials that can capture carbon emissions before they enter the atmosphere. With further refinements, it could also one day be applied to proteins, especially enzymes.

"Being at the frontier of science and solving a very complex problem that has not been addressed before is always very exciting," Haranczyk says.

 

President Obama today named Warren Washington, a senior scientist at the National Center for Atmospheric Research (NCAR), as one of 10 eminent researchers to be awarded the National Medal of Science. The recipients of the science medal and of the National Medal of Technology and Innovation will receive their awards-the highest honor bestowed by the U.S. government on scientists, engineers, and inventors-at a White House ceremony later this year.

"The extraordinary accomplishments of these scientists, engineers, and inventors are a testament to American industry and ingenuity," President Obama said. "Their achievements have redrawn the frontiers of human knowledge while enhancing American prosperity, and it is my tremendous pleasure to honor them for their important contributions."

"We are delighted that Warren's many years of dedicated research in climate science are being recognized with this extraordinary honor," said Roger Wakimoto, NCAR director. "His scientific leadership, innate diplomacy, as well as the mentorship to future generations of scientists have deeply and profoundly impacted our field."

Richard Anthes, president of the University Corporation for Atmospheric Research (UCAR), which manages NCAR, added: "It is a well-deserved honor for Warren as well as the atmospheric sciences, the National Science Foundation (NSF), and the UCAR and NCAR community.  Warren is a wonderful scientist who has been at the forefront of climate modeling for 40 years.  Even more importantly, he is a kind and generous person."

Washington is an internationally recognized expert on atmospheric science and climate research and a pioneer in using computer models, which employ fundamental laws of physics to predict future states of the atmosphere, to study Earth's climate. He has served as a science advisor to former presidents Carter, Reagan, George H. W. Bush, Clinton, and George W. Bush, published almost 200 papers in professional journals, and garnered dozens of national and international awards. He also served on the National Science Board for 12 years and was its chair for 2002 to 2006.

Washington became one of the first developers of groundbreaking atmospheric computer models in collaboration with his colleague, Akira Kasahara, when he came to NCAR in the early 1960s. With support from NSF and the Department of Energy, Washington subsequently worked to incorporate the oceans and sea ice into climate models. Such models were used extensively in the 2007 assessment by the Intergovernmental Panel on Climate Change, for which Washington and a number of scientists at NCAR and around the world shared the 2007 Nobel Peace Prize.

"I am very pleased to receive this honor, which recognizes not only my work but that of my many colleagues whom I've had the pleasure of working with for more than 45 years," Washington said. "Akira Kasahara and Jerry Meehl, at NCAR, contributed significantly to the development of computer climate models, and support from NSF and the Department of Energy enabled us to make research advancements that I hope will contribute to mankind's ability to sustain this planet." 

As the second African-American to earn a doctorate in the atmospheric sciences, Washington has served as a role model for generations of young researchers from many backgrounds, mentoring numerous undergraduate and graduate students. In 1999, Washington won the Dr. Charles Anderson Award from the American Meteorological Society "for pioneering efforts as a mentor and passionate support of individuals, educational programs, and outreach initiatives designed to foster a diverse population of atmospheric scientists."

Washington was born and grew up in Portland, Oregon. He became interested in science in grade school, going on to earn a bachelor's degree in physics and master's degree in meteorology from Oregon State University, and then a doctorate in meteorology from Pennsylvania State University. In 1963, he joined NCAR as a research scientist.
