Leading-Edge Data Analytics and Visualization Enable Breakthrough Science on Blue Gene/P

14.04.2009
Most science research programs that run on high-performance computers like the IBM Blue Gene/P Intrepid at the Argonne Leadership Computing Facility (ALCF) generate enormous quantities of data that represent the results of their calculations. But scientists can also use the ALCF to visualize, explore and communicate their findings as highly accurate simulations and often beautiful images.

The ALCF's ability to visualize such enormous quantities of data is made possible by of the world's largest graphics processing units (GPU). Nicknamed Eureka, this installation of NVIDIA Quadro Plex S4 external GPUs allows researchers to better understand the data they produce with Intrepid at the ALCF. The powerful installation provides more than 111 teraflops and more than 3.2 terabytes of RAM.

"Eureka provides a vital link between simulation and analysis by allowing scientists to probe and interrogate their data in an interactive manner," said Argonne computational scientist Paul Fischer. Since Eureka and Intrepid share a disk, there is no need to move data between machines. " Eureka dramatically reduces the amount of time needed to create these hugely complex visualizations, while greatly boosting their quality."

The ALCF's Intrepid provides resources for the U.S. Department of Energy's (DOE) Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program, which supports computationally intensive projects from industry, scientific researchers and research organizations.

Using software developed both at Argonne and externally, computer scientists have visualized data with Eureka for DOE INCITE projects focusing on turbulent thermal transport in sodium-cooled nuclear reactor cores, cardiac rhythm disorders and Type Ia supernovae, which are among the brightest and most powerful exploding stars in the universe.

"Eureka delivers a quantum leap in visual compute density, enabling breakthrough levels of productivity and capability in visualization and data analysis," said Craig Dunwoody, CEO of GraphStream, Inc. in Belmont, Calif., the supplier of scalable computer systems that provided Eureka.

Eureka incorporates four high-end graphics cards and places them in a configuration known as a "pizza box." Because the cards are packed so closely together, this configuration helps to reduce the complicated power and cooling issues associated with the graphics cards. Eureka needs only four racks to hold the same number of cards that previous configurations required more than 10 racks to accommodate.

The heart of Eureka's data-management system contains a nine-switch complex that supports up to 2,048 connections, each of which simultaneously exchanges data at roughly 1 billion bytes per second. The storage system consists of a bank of more than 10,000 disk drives that will send and receive data from the Blue Gene/P's more than 100,000 processors. Altogether, this system can deliver nearly 80 billion bytes per second to and from the disk—the equivalent of transferring the content of 100 full CDs every second.

Argonne operates the ALCF for the DOE Office of Science as part of the larger DOE Leadership Computing Facility strategy. DOE leads the world in providing the most capable civilian supercomputers for science.

Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation's first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America 's scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy's Office of Science.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
