New Grid desktop tool making flood prediction easier


A new tool developed under the IST CROSSGRID project aims to make running applications over the distributed computing environment of the Grid even easier. It currently is being used to help predict flooding across Europe.

Led by the Polish supercomputing institute Cyfronet, 21 partners in 11 countries across Europe are working to extend the Grid environment to a new category of practical applications. One of the key tools they have developed is the migration desktop, which is designed to support easy integration of these applications with the Grid environment.
"The migration desktop is a service that allows you to define the environment for easy integration of your application," says project coordinator Michal Turala of Cyfronet. "It’s a kind of user-friendly interface for whatever application you want to use."

Now a working prototype running in a Linux environment, the migration desktop is being further refined in preparation for the close of the project in February 2005. The desktop is already used to manage a new breed of distributed computing applications that the Grid infrastructure makes possible - in biomedics, in flood prevention, in pollution forecasting and in computation-heavy physics.

Flood prediction an urgent need

The flood prevention application is typical of these new distributed computing areas. It is a kind of virtual workgroup that uses CROSSGRID services to connect together the experts, data and processing resources needed to support fast decision-making in flooding crises.

The application’s main component is a highly automated flood warning system, based on data such as rainfall, snowmelt runoff and topographical variations. Predicting likely flooding requires extensive processing resources to carry out the meteorological simulation required, as well as handling the data from satellite sensing, hydraulic water flow models and more.

The project’s work in this area has acquired a new urgency since the severe flooding that devastated many parts of central Europe in August 2002. Tens of thousands had to be evacuated from their homes in six countries, and German officials have estimated that repairing the damage will cost billions of euros.

"The migration desktop is the tool that integrates the work of all the researchers across Europe working on this flood prevention application," says Turala. "It helps us integrate all the different data used in the flood prevention system, and runs it on the Grid."

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
