OpenMSI wins R & D 100 Award
OpenMSI is the most advanced tool for analyzing and visualizing mass spectrometry instruments (MSI) data that is available via web-browser. MSI technology enables scientists to study tissues, cell cultures, and bacterial colonies in unprecedented detail at the molecular level. Nowadays, MSI datasets range from tens of gigabytes to several terabytes. Thus, basic tasks like opening a file or plotting spectra and ion images become insurmountable challenges. OpenMSI overcomes these obstacles by making highly optimized computing technologies available via a user-friendly interface. Because OpenMSI leverages NERSC resources to process, analyze, store, and serve massive MSI datasets, users can now work on their data at full-resolution and in real-time without any special hardware or software. They can also access their data on any device with an internet connection. Ben Bowen of the Environmental Genomics and Systems Biology Division and Oliver Ruebel of the Computational Research Division led the development of the technology. Several other DST and NERSC personnel were involved in the development of this technology.

Best Paper Award at the IEEE Visualization Large Data Analysis and Visualization Symposium
Alexy Agronovsky of UCD was the lead author on the paper "Improved Post Hoc Flow Analysis Via Lagrangian Representations" which won Best Paper Award at the IEEE Visualization Large Data Analysis and Visualization Symposium. The basic idea is that flow field analysis can be done more accurately using a Lagrangian basis rather than an Eulerian basis, and that the work needed to produce the Lagrangian analysis can be done in situ, which results in not only better (more accurate) analysis but also at much less I/O cost. Hank Childs of DST led the team. Additional contributors to the paper are David Camp, Christoph Garth, E. Wes Bethel, and Kenneth I. Joy.More information about the symposium can be found here.

Craig Tull Leading Multi-Disciplinary Team Enabling the SPOT Suite Transformation at ALS Beamlines
Earlier this year, the ALS became the first and only facility worldwide to fully automate GISAXS/GIWAXS measurements. This tool is primarily used to characterize the assembly and shape of nanoscopic objects at surfaces or buried interfaces in thin films—including materials like organic photovoltaics, fuel cell membranes or batteries. Combine this capability with SPOT Suite, and researchers can run experiments at this beamline from anywhere in the world, provided they have Internet access. Users can mount their samples onto barcoded sample holders at home and ship them to the ALS. At the facility, a robot arm transfers each new sample to the measurement stage, where it is automatically aligned into grazing incidence using the X-ray beam. A barcode reader informs the computer system which sample is mounted and how to run the sample. Data acquisition software then moves the sample to all angles pre-specified by the researcher and chooses the appropriate exposure time automatically for each image. As images are collected, SPOT Suite sends the data to NERSC via ESnet for scientists to access and view any time. “This automated system represents a significant leap forward in terms of labor saving, ease of use and throughput,” says Alexander Hexemer, who manages the GISAXS/GIWAXS beamline at the ALS.

DST Team Contributes to Developing Tools to Reduce Greenhouse Gases at the Source
Despite advances in alternative energy sources, the United States will continue to rely on coal-fired power plants to generate much of the nation's electricity for the next 20 years or more. While coal is an economically viable fuel, its environmental cost is high-in 2011, coal accounted for 34 percent of the energy-related carbon dioxide (CO2) emissions in the United States. This is why a U.S. Department of Energy project, called the Carbon Capture Simulation Initiative (CCSI), is bringing together America's national laboratories, industry and academic institutions, to develop and deploy state-of-the-art computational modeling and simulation tools to accelerate the commercialization of carbon capture technologies in power plants. As part of this collaboration, computational researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) are playing key roles in the development of the computational tools. on its industry advisory board.
