We report on cosmological N-body
simulations which run over up to 4
supercomputers across the globe. We
achieved to run simulations on 60 to 750
cores distributed over a variety of
supercomputers. Regardless of the
network latency of 0.32 s and the
communication over 30.000 km of optical
network cable we are able to achieve up
to 92% of the performance compared to
an equal number of cores on a single
supercomputer.
Sharing ideas and sharing data: Researchers and Web 2.0Eric Meyer
Title: Sharing ideas and sharing data: Researchers and Web 2.0
Presenters: Lucy Power and Eric T. Meyer
Abstract: In this presentation, two case studies will be used to illustrate the types of incentives and barrier researchers face when deciding to share ideas and data using Web 2.0 tools and resources. The first case, Friendfeed, is a tool used by life scientists to disseminate, filter and discuss research and professional issues and ideas. The second case is about geospatial map sharing, early efforts to share maps that were hindered by legal barriers, and recent successful efforts to change the law in a way that will enable much more sharing. In both of these cases, researchers had a number of similar incentives to share, but also barriers to doing so. Among the incentives were a desire for openness in science, the benefits of networks, advantages of scale, and the ability to share the effort it takes to filter complex ideas and data. Barriers to sharing, however, include cultural differences among fields and institutions, institutional and individual concerns about protecting intellectual property, and the challenge of changing research behaviours. In both cases, technological limitations were not a particular barrier to sharing, unlike some common perceptions of the challenges of engaging researchers with technology.

Although unmanned aerial vehicles (UAVs) were mostly studied and used for military purposes before, they
have become very popular recently for both civil uses, such as law enforcement and crop survey, and for
potential commercial uses such as grocery delivery and Internet extension. Researchers investigating new
networking protocols for UAV networks usually need the help of simulations to test their protocol designs,
particularly when networks of large scales are desired in their tests. One choice that researchers need to
make in the simulation of UAV networks is the radio propagation model for the air links. In this paper we
compare the three radio propagation models that are available in the ns2 network simulation package and
investigate if the choice of one particular model would have a significant impact on the simulation results
for UAV networks.

New implementations for concurrent computing applications of 3D networks using corresponding nano and field-emission controlled-switching components are introduced. The developed implementations are performed within 3D lattice-based systems to perform the required concurrent computing. The introduced 3D systems utilize recent findings in field-emission and nano applications to implement the function of the basic 3D lattice networks using nano controlled-switching. This includes ternary lattice computing via carbon nanotubes and carbon field-emission techniques. The presented realization of lattice networks can be important for several reasons including the reduction of power consumption, which is an important specification for the system design in several future and emerging technologies, and in achieving high performance and reliability realizations. The introduced implementations for 3D lattice computations, with 2D lattice networks as a special case, are also important for the design within modern technologies that require optimal design specifications of high speed, high regularity and ease-of-manufacturability, such as in highly-reliable error-correcting signal processing applications.

Dr. Frank Wuerthwein from the University of California at San Diego presentation at International Super Computing Conference on Big Data, 2013, US Until recently, the large CERN experiments, ATLAS and CMS, owned and controlled the computing infrastructure they operated on in the US, and accessed data only when it was locally available on the hardware they operated. However, Würthwein explains, with data-taking rates set to increase dramatically by the end of LS1 in 2015, the current operational model is no longer viable to satisfy peak processing needs. Instead, he argues, large-scale processing centers need to be created dynamically to cope with spikes in demand. To this end, Würthwein and colleagues carried out a successful proof-of-concept study, in which the Gordon Supercomputer at the San Diego Supercomputer Center was dynamically and seamlessly integrated into the CMS production system to process a 125-terabyte data set.

Colors are the building blocks of the world we see. At the most basic level color allows us to identify what may be poisonous or edible, hot or cold, typical or abnormal and so much more. Despite the importance of color, it's often overlooked or oversimplified for data visualization. Combining these facts with the utility of color in data visualization I'll discuss color theory and how we can optimize the exploration and understanding of text mining.
Slides from the Innovation Enterprise conference on data visualization. The talk focusses on exploratory data analysis and and the power of graphics. Towards the end, the talk goes into keeping data exploration a realtime process by sampling data that would put CPUs under pressure for a long time.
The slides are meant to be additional to the verbal presentation, so the slides may be a bit hard to follow.
