The BlueBRIDGE approach to collaborative research

  1. 1. BlueBRIDGE receives funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 675680 The BlueBRIDGE approach to collaborative research Gianpaolo Coro CNR, Italy
  2. 2. Context Progress in Information Technology has changed the paradigms of Science  The large and fast increase of volume and complexity of data requires new approaches to collect-curate-analyse the data  This requires new tools to guarantee exchange and longevity of the data and of the reapplication of the experiments
  3. 3. Big Data • Large volume • High generation velocity • Large variety • Untrustworthy (veracity) • High complexity (variability) Big Data: a dataset with large volume, variety, generation velocity, containing complex and untrustworthy information that requires nonconventional methods to extract, manage and process information within a reasonable time.
  4. 4. New Science Paradigms  Open Science: make scientific research, data and dissemination accessible to all levels of an inquiring society, amateur or professional. Keywords: Open Access, Open research, Open Notebook Science  E-Science: computationally intensive science is carried out in highly distributed network environments that use large data sets and require distributed computing and collaborative tools. Keywords: Provenance of the scientific process, Scientific workflows  Science 2.0: process and publish large data sets using a collaborative approach. Share from raw data to experimental results and processes. Support collaborative experiments and Reproducibility-Repeatability-Reusability (R-R-R) of Science. Keywords: collaborative and repeatable Science
  5. 5. Requirements for IT systems • Support collaborative research and experimentation • Implement Reproducibility-Repeatability-Reusability of Science • Allow sharing data, processes and findings • Grant free access to the produced scientific knowledge • Tackle Big Data challenges • Sustainability: low operational costs, low maintenance prices • Manage heterogeneous data/processes access policies • Meet industrial processes requirements
  6. 6. e-Infrastructures e-Infrastructures enable researchers at different locations across the world to collaborate in the context of their home institutions or in national or multinational scientific initiatives. • People can work together having shared access to unique or distributed scientific facilities (including data, instruments, computing and communications). Examples: Belief, OpenAire, i-Marine, EU-Brazil OpenBio,
  7. 7. Virtual Research Environments • Define sub-communities • Allow temporary dedicated assignment of computational, storage, and data resources • Manage policies • Support data and information sharing Integrates e-Infrastructure Unified Resource Space Enables VRE VRE VRE WPS External e-Infrastructures
  8. 8. Virtual Research Environments Innovative, web-based, community-oriented, comprehensive, flexible, and secure working environments. • Communities are provided with applications to interact with the VRE services • Client services are provided both with APIs (Java, R) and simple HTTP-REST interfaces
  9. 9. VREs Example The D4Science e-Infrastructure D4Science supports scientists in several domains 1. More than 25 000 taxonomic studies per month 2. More than 60 000 species distribution maps produced and hosted 3. Used to build a pan- European geothermal energy map 4. Processing and management of heterogeneous environmental and Earth system data 5. Enhances communication and exchange in Linguistic Studies, Humanities, Cultural Heritage, History and Archaeology
  10. 10. BlueBRIDGE VREs Stock Assessment assess the health status of fisheries stocks. assessment CMSY model Marine Protected Areas reduce adverse impact of human activities (e.g. fishing, aquaculture, tourism) on ecosystems, and ensure these activities are properly embedded in policy frameworks. impact-maps
  11. 11. Education VREs Lecture-style: the course topics stress is different depending on the audience Interactive: after each explained topic, students do experiments Experimental: students reproduce the experiment shown by the teacher and possibly repeat it on their own data Social: students communicate via messaging or VRE discussion panel • 1 course/year In Pisa • 1 course/year In Paris • 12 courses In Copenhagen International Council for the Exploration of the Sea • 38 courses All over the world +1000 attendees
  12. 12. Social networking is key to share information in e-Infrastructure BlueBRIDGE offers a continuously updated list of events / news produced by users and applications User-shared News Application- shared News Share News BlueBRIDGE VREs: Social Networking
  13. 13. A free-of-use folder-based file system allows managing and sharing information objects. Information objects can be • files, dataset, workflows, experiments, etc. • organized into folders • shared • disseminated via public URLs BlueBRIDGE VREs: The Workspace – an online files storage system
  14. 14. Storage Databases Cloud storage Geospatial data Metadata generation and management Harmonisation Sharing Data management Cloud computing Elastic resources assignment Multi-platform: R, Java, Fortran Processing BlueBRIDGE Facilities: Overview
  15. 15. Data Processing
  16. 16. • Experiments on Big Data • Sharing inputs and results • Save the provenance of experiments • Supports R-R-R of experiments WPS REST • Input/Out • Parameters • Provenance Cloud Computing Platform

Scientific Workflow Script provider Updates the script on his private Workspace The service downloads the script on-the-fly A user executes an experiment on his/her data The output, the input and the parameters can be shared with another user This user can execute the experiment again and share the computation with the other user 1 2 3 4 5 6 7 89 10
  28. 28. Limitations and requirements Input OutputScript Script Required Provided Issues:  Code is often designed for one precise data set  Often, prototype scripts have code that is not separable from the I/O In the context of e-Infrastructures and Science 2.0:  Modularity is necessary for integration  Scripts should be re-organised in a way they could be re-used on other data without changing the code Vs
