The remote sensing information service grid node (RSIN) is a tool for dealing with climate change and quantitative environmental monitoring. Based on the high-throughput computing grid, RSIN enables a workflow management system for data placement. The accompanying unified data-and-computation-schedule algorithm helps load balancing between and within workflow steps.
NAREGI's middleware stack provides comprehensive support for coupled applications in the nanoscience discipline. The authors describe several mechanisms that are application-area agnostic and can be applied to other disciplines, such as weather and climate simulations, multiresolution simulation in life sciences, and other complex systems.
The Land Information System (LIS) is a multiscale hydrologic modeling and data assimilation framework that integrates the use of satellite and ground-based observational data products with advanced land-surface modeling tools to aid several application areas, including water resources management, numerical weather prediction, agricultural management, air quality, and military mobility assessment.
Through the development of new classes of software, algorithms, and hardware, data-intensive applications provide timely and meaningful analytical results in response to exponentially growing data complexity and associated analysis requirements.
Timing is everything. Neurons fire in time-locked fashion to propagate signals and form memories. The cell division cycle, the process by which an adult cell divides into two daughter cells, is carefully orchestrated by rises and decays of regulating protein concentrations. Engineered systems, like data centers, also involve temporal coordination. A few months back, the music service Last.fm had to...
Hierarchical graphs provide a data structure to support a programming model that aims to improve understandability by creating an architectural basis for building inspectable systems.We engage developers in constructing and exposing a runtime model of a system in a clear and structured way, thereby enabling them to build inspectable systems. This approach rests on the intuition that by supporting...
Great progress has been made in standardizing 2D medical images, but the standardization of 3D medical models is still lacking. The first Web extra at http://youtu.be/J_h3Pcono7A is a video in which a shoulder muscle is rendered based on a fresh cadaver and then laid out on a computer. The pattern is then applied to a 3D model of a shoulder, with corresponding muscle layers and connections to the...
A grid-computing platform facilitates geocomputational workflow composition to process big geosciences data while fully using idle resources to accelerate processing speed. An experiment with aerosol optical depth retrieval from satellite data shows a 25 percent improvement in runtime over a single high-performance computer.
Powerful computers and advanced sensors enable precise simulations of the atmospheric state, requiring data assimilation to connect simulations to real-world sensor data using statistical mathematics and dynamical systems theory. Numerical weather prediction (NWP) thus enables simulations that more closely represent the real world. The authors explore the NWP-associated challenges in managing big...
Operational NoSQL systems are relatively new in the data-management ecosystem, and there is much confusion about their capabilities and how they differ from traditional relational database systems. This summary of characteristics clearly distinguishes the two system classes and provides a glimpse into directions for future work.
