Enabling Innovation and Discovery through Data-Intensive High Performance Cloud and Big Data Infrastructure

July 29, 2014 2:34 pm | by George Vacek, DataDirect Networks | Blogs | Comments

As the size and scale of life sciences datasets increases — think large-cohort longitudinal studies with multiple samples and multiple protocols — so does the challenge of storing, interpreting and analyzing this data. Researchers and data scientists are under increasing pressure to identify the most relevant and critical information within massive and messy data sets, so they can quickly make the next discovery.

K Computer Runs Largest Ever Ensemble Simulation of Global Weather

July 25, 2014 2:25 pm | by RIKEN | News | Comments

Ensemble forecasting is a key part of weather forecasting. Computers typically run multiple simulations using slightly different initial conditions or assumptions, and then analyze them together to try to improve forecasts. Using Japan’s K computer, researchers have succeeded in running 10,240 parallel simulations of global weather, the largest number ever performed, using data assimilation to reduce the range of uncertainties.

Multi-Bit Spin for MRAM Storage may Rival Flash Memory

July 23, 2014 3:20 pm | by American Institute of Physics (AIP) | News | Comments

Interest in magnetic random access memory (MRAM) is escalating, thanks to demand for fast, low-cost, nonvolatile, low-consumption, secure memory devices. MRAM, which relies on manipulating the magnetization of materials for data storage rather than electronic charges, boasts all of these advantages as an emerging technology, but so far it hasn't been able to match flash memory in terms of storage density.

Breakthrough Laser May Play Crucial Role in Development of Quantum Computers

No-wait Data Centers: System could reduce Transmission Delays by 99.6 Percent

July 18, 2014 3:59 pm | by Larry Hardesty, MIT | News | Comments

Big Web sites usually maintain their own “data centers,” banks of tens or even hundreds of thousands of servers, all passing data back and forth to field users’ requests. Like any big, decentralized network, data centers are prone to congestion: Packets of data arriving at the same router at the same time are put in a queue, and if the queues get too long, packets can be delayed.

Fundamental Chemistry Findings Could Help Extend Moore’s Law

July 16, 2014 11:49 am | by Lawrence Berkeley National Laboratory | News | Comments

Over the years, computer chips have gotten smaller, thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore’s Law. But there’s one component of the chip-making process in need of an overhaul if Moore’s law is to continue: the chemical mixture called photoresist.

The Cray XC30 system will be used by a nation-wide consortium of scientists called the Indian Lattice Gauge Theory Initiative (ILGTI). The group will research the properties of a phase of matter called the quark-gluon plasma, which existed when the universe was approximately a microsecond old. ILGTI also carries out research on exotic and heavy-flavor hadrons, which will be produced in hadron collider experiments.

Scientists Track Quantum Errors in Real Time, Step Toward Age of Quantum Computing

July 15, 2014 4:33 pm | by Holly Lauridsen, Yale University | News | Comments

Scientists have demonstrated the ability to track real quantum errors as they occur, a major step in the development of reliable quantum computers. Quantum computers could significantly improve the computational power of modern computers, but a major problem stands in the way: information loss, or quantum errors. To combat errors, physicists must be able to detect that an error has occurred and then correct it in real time.

The solar panels that Idaho inventor Scott Brusaw has built aren't meant for rooftops. They are meant for roads, driveways, parking lots, bike trails and, eventually, highways. Brusaw, an electrical engineer, says the hexagon-shaped panels can withstand the wear and tear that comes from inclement weather and vehicles, big and small, to generate electricity.

Chemists Discover Boron Buckyball

July 15, 2014 11:55 am | by Brown University | News | Comments

The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a new ball on the pitch. Researchers have shown that a cluster of 40 boron atoms forms a hollow molecular cage similar to a carbon buckyball. It’s the first experimental evidence that a boron cage structure — previously only a matter of speculation — does indeed exist.
