The Astro Community and DCIs in Europe and the role of Astro-CG C. Vuerli - INAF
Outline • EGI and NGIs • The Astro Community in EGI • Other projects and initiatives • Interactions between DCIs and DDIs • Horizon 2020 • New astronomical projects • Challengesand possible answers • Astro-CG and its potential strength • But how should Astro-CG be operated? 2
EGI and NGIs • Presentation by Steve Brewer at the OGF35/Astro-CG session 3
The Astro Community in EGI • MAGIC and Planck: the first astronomical projects in EGEE • First porting of astro applications (five funded astro partners in EGEE-III) • The Astro Community recognized as HUC in EGI • Partnership in EGI-InSPIRE to develop and maintain astro-dedicated tools and services (WP SA3, Task 5) and prepare their long term sustainability • Visualization tools • Interoperability of different DCIs • Interoperability of DCIs and DDIs 4
SHIWA: Project Objectives • Enable user communities to share their WFs • Publish the developed WFs • Access and re-use the published WFs • Build multi-workflows from the published WFs • Toolset: • SHIWA Simulation Platform • WF Repository (production) • SHIWA Portal (production) • SHIWA Desktop (prototype) 5
SCI-BUS: Motivations There are many user communities who would like to access several DCIs (grids, clouds, clusters) in a transparent way They do not want to learn the peculiar features of the used DCIs They want to concentrate their scientific application Therefore they need a science gateway 6
SCI-BUS: MainObjectives Create a generic-purpose gateway technology Elaborate an application-specific gateway building technology and customisation methodology Establish production gateway services both for NGIs (horizontal user communities) and various science communities (vertical user communities) Create and maintain a Liferay portlet repository that enables the quick creation of user specific customised gateways Develop business models to guarantee sustainability and commercial exploitation 7
SCI-BUS: Generic Gateway • Based on Liferay • WS-PGRADE (Web Services Parallel Grid Runtime and Developer Environment) • gUSE(Grid User Support Environment) architecture • General purpose • Workflow-oriented portal framework • Supports the development and execution of workflow-based applications 8
SCI-BUS: gUSE/WS-PGRADE • Scalable architecture based on collaborating services • Seamless access to various types of DCIs: • clusters • service grids • desktop grids • clouds • Advanced data-flows and workflow concept: • Embedded workflows • Parametric nodes • Legacy codes • Web services • Advance input data management: • Cross product • Dot product 9
Other projects and initiatives • Which other projects? • It is not trivial to be aware of DCI-related initiatives in progress (or planned) within astro projects • Why? It could happen that… • People don’t know the existence of a coordination at European level • People don’t see any convenience if they coordinate within EGI • People are overloaded and forced to focuson key topics of their projects/activities 10
DCIs-DDIs interactions • Interactions between computing and data e-Infrastructures are crucial for astronomy • Data repositories play a key role • The definition of standards enabling DCIs and DDIs to share and access data repositories is of utmost importance • New astro projects try to face and overcome this gap but more (and coordinated) effort is still necessary to fully achieve this objective 11
Horizon 2020 • It is the forthcoming (starting in 2013) European Framework Programme for Research and Innovation • Special emphasis is put on data exploitation and data preservation • Horizon 2020 seems then to be strongly data-oriented • Various initiatives in progress to make the astro community ready to answer to Horizon 2020 calls • In this new scenario the interoperability between DCIs and DDIs become crucial 12
New projects: challenges • The size • Large scale projects spanning over different countries and involving many Institutes • Their efficient management is not trivial • Technological advances • Need to operate astronomical instrumentation increasingly powerful and sophisticated • New data processing/storing challenges • Avalanches of complex data to process and archive in a reasonable time • Cross-correlation of data coming from different projects and facilities • Long term preservation of produced data to maximize their scientific exploitation 13
New projects: possible answers • Enforce the collaboration between projects, research groups and Institutes • Be aware of new opportunities offered by advances of technologies sitting behind DCIs • Joint analysis of their respective requirements and needs in terms of tools and services • Explore together and jointly with IVOA • The interoperability issue between DCIs and DDIs • Common standards in accessing and processing data • New challenges coming from topics like data preservation and data exploitation • How to manage legacy data and legacy software • Improve the transfer/sharing of knowledge • Improve the communication level and the flow of information • between different projects and initiatives • with coordinating entities like OGF and EGI 14
Astro-CG potential strength • Strength points empowering Astro-CG • Its worldwide geographical coverage • Its mission • Sharing of expertize and knowledge • Sharing of common issues • Collaboration in looking for and providing possible solutions and interoperability paths between different e-Infrastructures and the underlying technologies • Definition of services and interfaces enabling the integration of e-Infrastructures and of their related resources • Understanding and overcoming issues and limitations that hamper the exploitation of DCIs and their related technologies • The liaison group with IVOA (GWS WG) 15
But how to operate Astro-CG? • Collaboration tools are crucial to open new communication channels • Passive tools and services • Dedicated mailing lists • Thematic web pages • Web based collaboration tools • Proactive initiatives • Establish individual contacts with astro projects and research groups • Definitely the most time-consuming and challenging task • Promote inter-projects communication channels and thematic discussion topics • Efficient exploitation of OGFs • At each OGF identify a hot topic and focus the Astro-CG session on it, fostering related communications by the various projects and RGs 16
