New research can spot cloud computing problems before they start

  • PDF
TechAndComputer (July 12, 2010) — Large-scale computer hosting infrastructures offer a variety of services to computer users, including cloud computing -- which offers users access to powerful computers and software applications hosted by remote groups of servers. But when these infrastructures run into problems -- like bottlenecks that slow their operating speed -- it can be costly for both the infrastructure provider and the user.

New research...

New computer program accurately simulates protein folding dramatically faster than previous methods

  • PDF
TechAndComputer (July 8, 2010) — All proteins self-assemble in a fraction of the blink of an eye, but it can take a long time to mimic the process. And there has been no guarantee of success, even with the most powerful computers -- until now.

Rice University researchers have come up with a computer program to accurately simulate protein folding dramatically faster than previous methods. It will allow scientists to peer deeper into the roots of...

Diamonds and the holy grail of quantum computing

  • PDF
TechAndComputer (June 30, 2010) — Since Richard Feynman's first envisioned the quantum computer in 1982, there have been many studies of potential candidates -- computers that use quantum bits, or qubits, capable of holding an more than one value at a time and computing at speeds far beyond existing silicon-based machines for certain problems. Most of these candidate systems, such as atoms and semiconducting quantum dots, work for quantum...

Over two billion hours served

  • PDF
TechAndComputer (June 18, 2010) — The Argonne Leadership Computing Facility (ALCF), located at the U.S. Department of Energy's (DOE) Argonne National Laboratory, has run over two billion processor-hours of computations at a mind-boggling speed of over 557 trillion calculations a second as it enables scientists and engineers to conduct cutting-edge research in just weeks or months rather than years.

"The ALCF is dedicated to enabling breakthrough...

U.S. government's move to cloud computing

  • PDF
TechAndComputer (June 9, 2010) — The National Institute of Standards and Technology (NIST) has been designated by Federal Chief Information Officer Vivek Kundra to accelerate the federal government's secure adoption of cloud computing by leading efforts to develop standards and guidelines in close consultation and collaboration with standards bodies, the private sector, and other stakeholders. Computer science researchers at NIST are working on...
