Scientific Software Development as a Social Process |

Software development is often understood as an engineering process. However, the factors that affect the success of a software development project are often human and social. The social context of software design and development is important: it provides social reinforcement for good practice. Study of high-performing software development teams makes it clear that the interplay between designers plays a crucial part both in nurturing creativity and innovation, and in embedding systematic practice and rigor. This talk will present key observations from empirical studies of expert software development that can be applied usefully to scientific software development. It will discuss why matching development practices to the context and purpose of scientific software can improve both software and scientific outcomes. It will draw on research in order to discuss how communication and collaboration can be fostered, and to identify what works (and what doesn’t work) in building collaboration in software development teams, whether co-located or distributed.

The NIF: an International User Facility for High Energy Density and Inertial Fusion Science |

Funding: * This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. #LLNL-ABS-628852
The National Ignition Facility (NIF), operational since March 2009, is transitioning to an international user facility for high-energy-density science (HEDS) and inertial confinement fusion (ICF) research. The NIF, the world’s largest and most energetic laser facility consists of 192 Nd-glass lasers, a control room and a target chamber. NIF is the first laser system built to demonstrate thermonuclear burn of deuterium-tritium–filled ICF capsules. NIF’s high-powered, high-energy lasers can compress and heat material to produce unique states of matter and radiation environments in the laboratory–conditions of interest to HEDS supporting national security and fundamental science. Achieving ignition on NIF will also demonstrate the target physics basis of ICF for energy production. The NIF laser’s unprecedented power, precision, and reproducibility, coupled with sophisticated target and diagnostic capabilities, are enabling leading edge experiments in the study of matter at extreme temperatures and pressures–conditions that exists in planetary interiors. This paper describes NIF’s unprecedented current and future capabilities and the experimental results achieved so far.

The landing of the car size rover “Curiosity” on Mars was one of the most challenging engineering achievements in robotic exploration. In this talk, I will describe the innovations and challenges in developing and landing Curiosity, the scientific results during the first year of operations, as well as how it fits in the overall program of planetary exploration and Earth observatories.

Designing for Longevity |
|

- A. Rose
The Long Now Foundation, San Francisco, USA

How do you build an monument scale sculptural machine that will last as long as civilization? How do you engage the people that visit it? For the last fifteen years The Long Now Foundation and Alexander Rose have been working on building this icon of long-term thinking. Rose is currently managing the 10,000 Year Clock project underway in West Texas where they have used purpose designed robots and explosives to excavate over 500 vertical feet through solid rock to house the Clock. Alexander will discuss the research and design process that has taken him as far as the arctic Seed Vault in Svalbard, to the ultra-secret Mormon geneological vaults in Salt Lake City. He will show the building process now underway for the 10,000 Year Clock that includes fabrication of the massive Clock itself.

GNU Radio and the USRP: Building a Community and an FPGA-based Software Radio |
|
| |
- M. Ettus
Ettus Research, Santa Clara, USA
|
|
| |
GNU Radio is a free software project for software radio. Matt Ettus joined the project shortly after it was founded in 2001. He soon realized that for the project to be truly successful, it needed low cost hardware on which to build those radios, and so he designed the Universal Software Radio Peripheral (USRP) in 2003 and 2004. Since then, both projects have achieved significant growth and success. In 2010, Matt's company, Ettus Research, was acquired by National Instruments, and it continues to produce products and free software for the community. This talk will cover the history of both projects, some of the technical details of the FPGA-based hardware architecture, and the community experience over its 12 years of active development.

Java Embedded Software: Disruptions Ahead |
|

The devices supporting our daily activities are becoming more sophisticated and better connected at an astonishing rate. The Internet of Things is driving an explosion of devices and data, revolutionizing industry, science and commerce. Devices are smarter, faster, and better connected. To support these trends, increasingly sophisticated embedded devices must be developed more quickly, yet must also be secure, robust, and maintainable. Java technology is ideally suited to support this complexity, whether embedded in a lightweight, low-cost secure ID card, supporting multiple systems of a large reactor, or any conceivable application between. This presentation will cover the evolution of the Java language and it's applicability to control systems specialists. Increasingly Java is being adopted within control systems due to its scalability, robustness, portability and developer productivity features. Peter will cover in detail the new capabilities of Java and provide an overview of the roadmap ahead; toward the Internet of Things.
