5. www.egi.euEGI-InSPIRE RI-261323 VERCE Virtual Earthquake and Seismology Research Community in Europe VERCE platform: – distributed computing and data management services – portal for Earthquakes Simulation and Earth Model evaluation. VERCE Science Gateway: – Based on gUSE/WS-PGRADE technology – Workflows – Globus GT5 and Unicore Data management layer – Based on a federation of iRODS nodes which stores private and public data and models (GridFTP, iRODS microservices, mongoDB) Requirements – AAI, Data manag. and sharing, information about resources available http://verce.eu

6. www.egi.euEGI-InSPIRE RI-261323 CLIPC – Climate4Impact portal Data from Earth System Grid Federation (ESGF): – distributed data repository with OpenID acess (6 PB of data), access is free AAI – Portal login with ESGF open id identifier – Uses x509 client certificates for server side data access Requirements – Reduce security complexity (OpenID, MyProxy, SSL, ports, delegation issues, etc…) – Data transfer is a bottleneck Portal dedicated to the climate impact community: based on 21 use cases from e.g, Deltares, Alterra, UvA

7. www.egi.euEGI-InSPIRE RI-261323 EIDA - European Integrated Data Archive EIDA is a distributed data center: – securely archive seismic waveform data and related metadata, gathered by European research infrastructures – provide transparent access to the archives by the geosciences research communities – Currently around 350 TB from 130 networks and 4500 stations – ArcLink protocol (GFZ technology) Member of EUDAT 2020 project Requirements – Secure storage – Users want to ‘see’ the repository as a unique source of information (integration) – AAI (transparent access)

8. www.egi.euEGI-InSPIRE RI-261323 EIDA stations

9. www.egi.euEGI-InSPIRE RI-261323 EPOS The European Plate Observing System (EPOS): – multidisciplinary research is made possible for a better understanding of the Solid Earth Science processes – long-term plan to facilitate integrated use of data, models and facilities from distributed and new research infrastructures Earthquakes, Volcanic Eruptions, Tsunamis, Tectonics, etc. – Huge community: 244 RI, 138 Institutions, 22 countries, many sensors – More than 2 PB of data (seismology + GNSS) EPOS will adopt an external ICT infrastructure Requirements – AAI – Data Integration – Workflow engines, PID, data staging, move computation to data, processing

10. www.egi.euEGI-InSPIRE RI-261323 Solid Earth Sciences part of EGI Earth Science community Embrace large variety of disciplines each having its own approaches and tools – No general infrastructure for Earth Science – Data from the climatology group stored via the Earth System Grid (ESG) on EGI resources – Different AA mechanisms Requirements – AAI – Discovery and automatic download of data sets from computation jobs – User interfaces via portals are not very popular in this discipline, different categories of users have to be catered for

11. www.egi.euEGI-InSPIRE RI-261323 GPS – Satellite Data EPOS Thematic Centre Services: – earth surface displacements maps – geophysical parameters retrieval – provided by 5 partners coming from different European countries – each service needs an infrastructure EPOSAR service – generation of displacement time-series by exploiting the existing huge SAR data – use of external computational infrastructures can be considered Requirements – processing of large data: from 150MB up to 10GB for 1 image according to the satellite – algorithm to reduce the processing time – WNs: 10-100 per processed area, RAM > 32 GB, – Network >10 Gbps among WNs – terabytes for each simulation, a solution is needed to stage data to computing

12. www.egi.euEGI-InSPIRE RI-261323 British Geological Survey British Geological Survey: – Involved in many scientific areas (geophysics, etc..) – owns an IT infrastructure – Involved in EPOS – Many web services already available Requirements – Lack of expertise to scale with computing capabilities: need help to understand the potentiality of a distributed e-infrastructure – Integration of scientific code into the infrastructure requires care

13. www.egi.euEGI-InSPIRE RI-261323 AAI Session Issues – X.509 is difficult for some users – Group management is weak in eduGAIN/FIM – Delegation, definition of roles – Too many protocols in use How to continue? First step focus on definition of roles ? – Collect use-cases: short-term actions and long-term actions. – Trying to identify and define common roles specification for the Earth Science communities could be a use-case – The e-infrastructure providers should be involved too in defining these roles – Some use case requirements will be input for the GÉANT 4 Enabling Users task AARC project

14. www.egi.euEGI-InSPIRE RI-261323 Data and computing Session Complexity of software stack. Too many software layers may affect community services sustainability Deploy and operation in production of community services – Reduce the number of pilots in favour of smaller-scale long-term collaborations Proceed gradually into the integration of e-Infrastructure services PID and DOI – based on the same technology (Handle System) and serve two different utilization scenarios (data and publication) – They can be combined (a DOI pointing to a publication which includes references to data sets through PIDs) but are not interchangeable – RDA has a specific working group to discuss on these topics GEANT to contribute to EGI/EUDAT/PRACE calls for use cases to ensure networking needs and support for any AAI issues

15. www.egi.euEGI-InSPIRE RI-261323 Cloud Session GEANT Cloud services is about providing access to existing cloud services in various ways – Catalogue and compliance to small set of clear key requirements – Procurement based on aggregated demand from NREN user base EGI offers a federated cloud for scientific communities – Already supporting use cases coming from various scientific disciplines – Ready to support more use cases – It could be listed in the GEANT catalogue

16. www.egi.euEGI-InSPIRE RI-261323 Conclusions & Follow-up GEANT, EGI, PRACE and EUDAT will collaborate on supporting scientific applications – EGI/EUDAT/PRACE calls for use cases coming soon – GEANT will contribute ensuring networking needs and support for any AAI issues – e-Infrastructure services integration (e.g. EGI-EUDAT cookbook)EGI-EUDAT cookbook 2 use cases identified to start pilots – CLIPC – Satellite Data / GPS – Pilots setup will start in the next weeks
