Il seminario presenta un approccio innovativo al trattamento dei dati sismici mediante la combinazione di software di processing open source allo stato dell'arte con tecnologie informatiche di grid computing, rendendo possibile ed efficiente l'utilizzo di risorse distribuite e amministrate in remoto per il calcolo e la gestione dei dati. Inoltre illustra i risultati ottenuti per tre diversi tipi di dati (onde di compressione, onde di taglio e multi-offset Ground-Penetrating Radar), tratti da studi idrogeofisici condotti in Sardegna e a Larreule (Francia).

Transcript

  • 1. Environmental and ImagingSciencesWEB Services: from Research to IndustrialApplications Ernesto Bonomi Energy and Environment CRS4 ernesto@crs4.it
  • 2. Motivation for DoingEnvironment is going to be a major issue.Since 50 years, environmental problems are aggravated by • overpopulation, • increases in agricultural productivity, • fast industrial development.Problems include • starvation and malnutrition, • demand for resources such as fresh water and food, • consumption of natural resources faster than the rate of regeneration (such as fossil fuels), • rising levels of atmospheric carbon dioxide, • global warming, and pollution.Strain on the environment causes a decrease in living conditions.Environmental engineering must grow rapidly from basicresearch and deal with the activities of monitoring andmanaging natural resources on an industrial scale.
  • 3. ObjectivePromoting an interdisciplinary view of energy andenvironmental problems, in which the mechanisms, be they physical, chemical, biological, or economic,are no longer analyzed and modeled as independent, butare investigated together with the support of • robust theoretical frameworks • accurate numerical tools • reliable reference data • large computing infrastructures • motivated funding partnersOrganizing the efficient use our collective intelligence tostudy solution strategies and design innovative applications
  • 4. From Modeling to Innovative ServicesProblem formalization Application planning Programming and optimization HPC application as a Cloud service
  • 5. Critical Issues• The development of software tools for collaborative activities allowing a transparent access to • network resources • data acquisition systems • storage and computing platforms • application software within a unique infrastructureAn integrated vision that requires high level skills for:• The fundamental understanding of physical, chemical and biological processes operating at different scales• Programming and implementing on HPC clusters with architectures in continuous evolution (multicore CPUs, GPUs and FPGAs)• Conceptualizing the data analysis process and development of tools for problem solving and decision support
  • 6. Real Collaborations and Virtual Organizations monitoring, Working Group 2: monitoring, and sustainable water resource Working Group 1: short management term prediction of extremeA Cloud/Grid is an eventsinfrastructure that allowsthe integrated andcollaborative use ofvirtualized resources Data servers Computational servers Working Group 3: information systems Connecting networks for the analysis of environmental and territorial data Numerical applications Information systemsowned and managed byone or more entities On the infrastructure, each virtual organization acts as a services provider while each partner, researcher or engineer, becomes the recipient

  • 10. Environmental Geophysical Imaging: a Cloud SolutionCreating a Cloud infrastructure for environmental geophysics• In-field Quality Control• Optimization of SR/GPR data acquisition/processing • Providing a browser-based user interface easily accessible from the acquisition field • On-the-fly processing of seismic data on the remote infrastructure • Running data-driven and highly parallel imaging and velocity analysis numerical tools • Enabling remote collaboration and monitoring of data acquisition
  • 11. Environmental Geophysical: Data Acquisition
  • 12. Environmental Geophysical: Data Processing Input SystemSeismic Records Processing Phases
  • 13. Environmental Geophysical: Quality ControlOn-site-acquisition quality control is difficult when stronglyvariable near-surface conditions are encountered• Success depends on acquisition parameters such as • recording time • sampling interval • source strength • maximum offset • receivers spacingIt is impossible to optimize in the field the acquisition Cloud services from on-site tablets and PCs using Wireless data transmission + remote HPC processing
  • 14. Acquisition Quality ControlPreprocessing and visualization using SU• Basic preprocessing steps can be applied fast and conveniently without locally installed processing package.Time imaging using CRS technology• Data-driven CRS imaging technology ---state-of-the-art in oil exploration--- enables highly automated data processing.• Velocity model building based on CRS results and time migration provide complementary subsurface information.Workflow editor:• Fast construction and processing of different workflows to find optimum processing parameters.
