A Database of Billions of Genes and Counting!
With support from NERSC, the IMG/M data management system, which supports the analysis of microbial communities sequenced by the Joint Genome Institute, crossed the boundary of 1 billion genes recorded in the system—more than any other similar system in the world. Read more.
The Great Gas Hydrate Escape
For some time, researchers have explored flammable ice for low-carbon or alternative fuel or as a place to store carbon dioxide. Now, a computer analysis at NERSC of the ice and gas compound, known as a gas hydrate, reveals key details of its structure. The results show that hydrates can hold hydrogen at an optimal capacity of 5 weight-percent, a value that meets the goal of a Department of Energy standard and makes gas hydrates practical and affordable. Read more.
Computing Steps Up to Capture, Keep Carbon Dioxide Underground
Many of the ideas underlying carbon capture and sequestration are either in laboratory tests or pilot studies. Using traditional scale-up processes to commercialize new research ideas in the power industry has historically taken 20 to 30 years. But DOE supports several computational projects to accelerate this process.
Researchers such as CRD’s Maciej Haranczyk use supercomputers to speed designs for new materials that sponge up carbon dioxide and systems that facilitate its large-scale capture. Other scientists use computation to better understand the geological and physical processes and lay the groundwork for approaches that will sequester gas underground. Read more in ASCR Discovery.
LDRD FY 2013 Call for Proposals
On January 24, Berkeley Lab Director Paul Alivisatos issued the Laboratory Directed Research and Development (LDRD) FY 2013 Call for Proposals. The LDRD program constitutes one of the principal means to seed innovative science and new research directions.
An important factor in judging proposals will be their support of competencies aligned with the Laboratory’s and DOE’s strategic directions. Multi-investigator and multi-divisional initiatives are particularly encouraged. Topics of special significance include projects that address the use of large-scale computation and data science. All projects should have a clearly stated problem (addressing a challenging scientific question, DOE mission, or national need); coherent objectives; and a well considered plan for leadership, organization, and budget.
The complete call, schedule, guidance, and forms are available here. Proposals should be put into the submission system by Friday, March 23, 2012.

Safety Note: When Is Noise Hazardous?
Everyone knows that exposure to high noise levels can cause hearing loss, but how do you know when noise levels are in the range that might be detrimental to your hearing? In general, noise may be at a hazardous level anytime that you must raise your voice to communicate with someone three feet away.
The best way to protect your hearing is to consistently use hearing protection whenever noise levels are above 85 decibels, irrespective of exposure duration. Hearing protection must be used all the time when working in high noise areas to get the full benefit.
Though noise levels in most LBNL computer rooms do not exceed 85 decibels, employees may prefer to wear earplugs or earmuffs when working for long periods of time in these areas. Noise-cancelling headphones require special approval from EHS, because not all of them are acceptable.
Here are some hearing safety resources:
- To have noise levels measured, contact Herb Toor at x5918.
- A recent LBNL Lesson Learned discusses the proper use of hearing protection.
- A recent NY Times article on noise-cancelling headphones highlights some of the popular models.
This Week’s Computing Sciences Seminars
Cloud Seminar: Storm: Distributed and Fault-Tolerant Real-Time Computation
Monday, January 30, 11:00 am–12:00 pm, 480 Soda Hall, UC Berkeley
Nathan Marz, Twitter.com
Storm makes it easy to write and scale complex real-time computations on a cluster of computers, doing for real-time processing what Hadoop did for batch processing. Storm guarantees that every message will be processed. And it’s fast — you can process millions of messages per second with a small cluster. Best of all, you can write Storm topologies using any programming language. Storm was open-sourced by Twitter in September of 2011 and has since been adopted by many companies around the world.
Storm has a wide range of use cases, from stream processing to continuous computation to distributed RPC. In this talk I will introduce Storm and show how easy it is to use for real-time computation.
NERSC Brown Bag: Large-Scale Nanostructure Simulations from X-Ray Scattering Data on Graphics Processor Clusters
Tuesday, January 31, 12:00–1:00 pm, OSF 943-238
Sherry Li, LBNL/CRD
X-ray scattering is a valuable tool for measuring the structural properties of materials used in the design and fabrication of energy-relevant nanodevices (e.g., photovoltaic, energy storage, battery, fuel, and carbon capture and sequestration devices) that are key to the reduction of carbon emissions. Although today’s ultra-fast X-ray scattering detectors can provide tremendous information on the structural properties of materials, a primary challenge remains in the analyses of the resulting data. We are developing novel high-performance computing algorithms, codes, and software tools for the analyses of X-ray scattering data.
In this paper we describe two such HPC algorithm advances. Firstly, we have implemented a flexible and highly efficient Grazing Incidence Small Angle Scattering (GISAXS) simulation code based on the Distorted Wave Born Approximation (DWBA) theory with C++/CUDA/MPI on a cluster of GPUs. Our code can compute the scattered light intensity from any given sample in all directions of space, thus allowing full construction of the GISAXS pattern. Preliminary tests on a single GPU show speedups over 125x compared to the sequential code, and almost linear speedup when executing across a GPU cluster with 42 nodes, resulting in an additional 40x speedup compared to using one GPU node. Secondly, for the structural fitting problems in inverse modeling, we have implemented a Reverse Monte Carlo simulation algorithm with C++/CUDA using one GPU. Since there are large numbers of parameters for fitting in the X-ray scattering simulation model, the earlier single CPU code required weeks of runtime. Deploying the AccelerEyes Jacket/Matlab wrapper to use GPU gave around 100x speedup over the pure CPU code. Our further C++/CUDA optimization delivered an additional 9x speedup.

LAPACK Seminar: Application of the Voronoi Tessellation for High-Throughput Analysis of Crystalline Porous Materials
Wednesday, February 1, 12:00–1:00 pm, 380 Soda Hall, UC Berkeley
Chris Rycroft, UC Berkeley and LBNL/CRD
Crystalline porous materials, such as zeolites, contain complex networks of void channels that are exploited in many industrial applications. Since the 1950s, they have been employed in common applications such as chemical catalysts and water softeners, and more recently there has been interest their use for new technologies such as carbon capture and storage. A key requirement for the success of any nanoporous material is that the chemical composition and pore topology must be optimal for a given application. However, this is a difficult task, since the number of possible pore topologies is extremely large: thousands of materials have been already been synthesized, and databases of millions of hypothetical structures are available.
We have developed tools for rapid screening of these large databases to automatically select materials whose pore topology may make them most appropriate for a given application. Many of the methods are based on computing the Voronoi network, which provides a map of void channels in a given structure. This is carried out using the free software library Voro++, which has been modified to properly account for three-dimensional non-orthogonal periodic boundary conditions.
Open Source Robotics
Wednesday, February 1, 12:00–1:00 pm, 310 Sutardja Dai Hall (Banatao Auditorium), UC Berkeley
Steve Cousins, President and CEO, Willow Garage
Over the next 10 years, personal robots (as opposed to industrial robots) have the potential to improve people’s lives by taking automation to a new level. Like personal computers of 30 years ago, the personal robotics industry will take off and become an economic engine. But robotics is a complex, multidisciplinary field, and fielding successful applications requires expertise ranging from hardware (mechanical and electrical) to social science. By working together on an open source software platform, we can accelerate progress in the field and more quickly field successful applications. Willow Garage has partnered with Stanford University and many other top robotics laboratories around the world to create such an open source code base. The robot operating system, ROS, is quickly becoming the de facto platform for robotics research. I will argue that most if not all robotics companies should join the ROS bandwagon, as a way to move the entire industry forward quickly.
