Porting a Seismic Network to the Grid
The chapter describes the experience and lessons learnt during customization of a seismic early warning system for the grid technology. Our goal is to shorten the workflow of an experiment, so that final users have direct access to data sources, i.e. seismic sensors, without intermediaries and without leaving the environment employed for the analysis. We strongly rely on remote instrumentation capabilities of the grid, a feature that makes this platform very attractive for scientific communities aiming at blending computational procedures and data access in a single tool. The expected outcome should be a distributed virtual laboratory working in a secure way regardless of the distance or the number of participants. We started to set up the application and the infrastructure as a part of the DORII (Deployment of Remote Instrumentation Infrastructure) project. In the following sections we will try to explain the steps that led us to integration, the experience perceived by the testers, the results obtained so far and future perspectives.
The work described is carried out under the DORII project, supported by the European Commission with contract number 213110. The authors would like to thank Mirko Corigliano for the analysis software ported into the grid and for the related explanations. The cooperation of Dip.Te.Ris at University of Genoa was fundamental to access the sensor network. In particular, the contribution received from Daniele Spallarossa and Gabriele Ferretti was very useful to fix the application. Finally, the work of Davide Silvestri in implementing the Instrument Managers and part of the Java library was highly appreciated.
