Reseachers run one million virtual machines to help flight botnet problem

Scientists at Sandia National Laboratories SNL have demonstrated a supercomputer running more than one million virtual computers that will provide insight into the behavior of botnets. Botnets are networks of infected computers zombies that can be remotely controlled, and are difficult to protect against and study since...

Application Sensitivity to Link and Injection Bandwidth on a Cray XT4 System

This paper describes the efforts to characterize application sensitivity to link and injection bandwidth on a Cray XT4 system. Link bandwidth is controlled by modifying the number of rails activated per network link. Injection bandwidth is controlled by modifying the speed of the HyperTransport connection between the Opteron and the...

Smart cars... from Sandia

Sandia National Laboratories SNL are more known for their research on nuclear weapons than for making our cars safer. Still, some SNL researchers are designing safety features for cars that can analyze human behavior. This could lead to smarter cars which would tell us that we're tired or tell our...

Boosting solar energy plants efficiency

Researchers at Sandia National Laboratories have invented a new way to make solar collector systems more energy efficient. The theoretical overlay photographic TOP technology developed at Sandia uses mirrors to focus radiation from the sun as a source of heat for power generation. In fact, they've created a mirror alignment...

Army tests energy microgrid

Roland Piquepaille blogs that the Army is working on an "energy surety" model with Sandia National Laboratories SNL. "Instead on relying on today's grid electricity system, this microgrid system will use small power generation units close to where people live and work. And it will use renewable energy...

An energy microgrid for the Army

Researchers from Sandia National Laboratories SNL are working with the U.S. Army on an energy surety model which soon will be tested by military bases. Instead on relying on today's grid electricity system, this microgrid system will use small power generation units close to where people live and work. And...

Scientists replicate the physics of a stellar jet in laboratory

Astronomers will tell you that among the most beautiful structures observed in the Universe are the intricate jets of matter speeding away from accreting stars, such as young proto-stars and stellar mass black holes. But they have a hard time explaining it. A pair of professors the University of Rochester...

Images: Supersize solar power

Utility-scale solar power plants--using everything from giant reflective dishes to plastic balloons--are changing the look of solar power.Parabolic troughs, one of which is shown here, have been around for 25 years, and the technology will be around for at least another 25. Parabolic troughs reflect sunlight to heat liquid carried...

CIA, FBI relying heavily on unreliable polygraph

In the age of retina scans and other biometric technology, it seems a bit anachronistic that the FBI and CIA are increasingly relying on the ancient polygraph test as an investigatory tool, but indeed they are, the Washington Post reports. And this even though there's a growing body...

A roundtrip to Mars in one day?

According to ideas developed in the 1950s, it should be possible to build an 'hyperspace' engine allowing a spacecraft to reach Mars in 3 hours. It would also allow us to travel to stars more that 10 light years away in 80 days by slipping into a different dimension. But...
