Los Alamos lets users customize the supercomputer software stack

For all their power, supercomputers require specialized software and applications, which makes it difficult for users running big data analyses – which comes with its own set of frameworks and dependencies -- to take advantage of the hardware.

To make it easier for researchers working with big data to use supercomputers, developers at Los Alamos National Laboratory have created a program called “Charliecloud” that uses a container approach to lets users package their own software stacks. (Full Story)

Entropy: a shot in the arm for IoT security?

With machine intelligence and massive cloud-driven compute power at our disposal, it is becoming easier and easier to ‘guess’ the codes that underpin encryption and crypto-based applications. Thus, entropy is needed.

In terms of mathematics, entropy is a lack of order or predictability and a gradual decline into a state of numerical disorder.

The technology is born out of a decade-long research project conducted by the quantum security team at the Los Alamos National Laboratory and is designed to strengthen cryptographic security systems from encryption in traditional datacenters and virtual cloud environments. (Full Story)

'Magic' alloy could spur next generation of solar cells

In what could be a major step forward for a new generation of solar cells called "concentrator photovoltaics," University of Michigan researchers have developed a new semiconductor alloy that can capture the near-infrared light located on the leading edge of the visible light spectrum.

Goldman's team combined on-the-ground measurement methods including X-ray diffraction done at U-M and ion beam analysis done at Los Alamos National Laboratory with custom-built computer modeling. (Full Story)

LANL divisions win quality awards

The Human Resources Division and the Quality and Performance Assurance Division at Los Alamos National Laboratory both received Performance Excellence Recognition awards from Quality New Mexico, a non-profit organization that helps New Mexico businesses and organizations improve organizational performance.

“We want to provide the best possible human resources products and services to our employees,” Human Resources Division Leader Sue Harris said. (Full Story)
