Modeling the Perfect Fluid

This visualization starts with particles from a nuclear collision that are compressed and heated up to create a Quark-Gluon-Plasma (QGP), which looks like a “blob” in the video. Once the QGP expands and cools down, it decays again into particles that can be measured by the research team’s experiments. This is a so-called “hybrid’ model, that basically uses the Ultrarelativistic Quantum Molecular Dynamics model (UrQMD), a microscopic model used to simulate (ultra)relativistic heavy ion collisons, to model very early and late reaction stages in the process. The model has been combined with a relativistic fluid dynamics calculation to depict the formation and evolution of a Quark-Gluon-Plasma.

Duke University physicist Steffen A. Bass uses big chunks of computing time to study the behavior of some of the universe’s most fundamental particles—quarks and gluons, which existed in an unbound state up until about a micro-second after the Big Bang. Read more

RENCI networking pros tapped for project to design the future Internet

CHAPEL HILL–RENCI’s networking research group is part of a team that will design a blueprint for a future version of the Internet.

The University of Massachusetts, Amherst, leads the $2.7 million, three-year project, named ChoiceNet, which is funded by the National Science Foundation. In addition to RENCI at UNC Chapel Hill, North Carolina State University and the University of Kentucky have roles in the project. The project complements the work of the NSF program, Future Internet Architecture (FIA). FIA’s goal is to stimulate innovative and creative research to explore, design, and evaluate trustworthy future Internet architectures.  Read more

International data grids to be highlighted in RENCI SC11 booth

SEATTLE, Nov. 9, 2011 – The RENCI/North Carolina booth (#2942) will be one of several on the SC11 show floor to participate in a demonstration that will connect booths in the Washington State Convention Center with large data sets in the U.S. and Europe, creating a distributed, high-speed international data grid that allows researchers to share, store and manage large data sets.

RENCI@SC11, Washington State Convention Center, Seattle

RENCI and its North Carolina partners at Duke and NC State universities will feature their work in an exhibit at SC11, the world’s premier conference for high performance computing, networking, storage and analysis, Nov. 14 – 17. Read more

RENCI to demonstrate on-demand resources and provisioning at SC11

SEATTLE, Nov. 1, 2011–Scientists studying data or compute-intensive problems require high bandwidth and computational resources, often from heterogeneous systems at different sites.

But they don’t need these resources all the time.

Ideally, a scientist studying the properties of new materials for producing solar energy, for example, would be able to grab a “slice” of a high-bandwidth pipeline, set their workflow in motion, grab compute resources in the cloud and then release those resources, so they could be used by other researchers in different configurations.

Look out PowerPoint: UNC students use Social Computing Room as a presentation tool

To paraphrase Marshall McLuhan, change the communication medium and you’ve changed the message.

It’s a concept that’s well understood by the students in Rebecca Nesvet’s English 102, (Writing in the Disciplines) classes at UNC Chapel Hill.

This semester, students worked in teams to develop presentations on a wide range of scientific fields of inquiry. But instead of expecting the usual PowerPoint slides filled with bulleted talking points, Nesvet brought them to RENCI’s Social Computing Room and turned them loose.  The room, with a floor-to-ceiling computer desktop that projects on all four walls, allows users to immerse themselves in panoramic montages of data and images.

Putting data in its place

Understanding data often requires understanding the geography associated with it.

Hurricane and storm surge models mean little unless tied to a specific location.  Trends in diseases and public health can be spotted and analyzed by comparing data from different counties, regions or states. Read more
