e-Science Introduction Eric Yen e-Science Workshop, March 2011
Outline • Workshop Overview • E-Science Basics • Landscape of e-Science • Application Development Concept • Security Infrastructure • Exemplar Applications 2
e-Science Workshop Overview • Objectives • Help user communities to take advantage of the global DCI – World Wide Grid • Engage close collaboration among regional user communities and with the Grid community • Target Audience • Both users and Grid/e-Science engineer • Of course, this is also good for novice to understand the e-Science, application development, related technology and the collaboration. • Two workshop on Natural Disaster Mitigation and Life Science are arranged. 3

e-Science Basics • “e-Science is about global collaboration in key areas of science, and the next generation of infrastructure that will enable it. ... e-Science will change the dynamic of the way science is undertaken.” • By John Taylor, former Director General of Research Councils UK • Vision: a globally connected scholarly community promoting the highest quality scientific research • e-Science refers to either computationally intensive science or data intensive science that is carried out in highly distributed computing environment. • WLCG, EGEE, EGI, TeraGrid, OSG, EUAsiaGrid, ! 5
e-Infrastructure/ Cyberinfrastructure • Driven by Data Deluge • Turning data into insight and knowledge base efficiently • Open, consistent and well-designed data format, interface, protocol and quality code • Searchability, accessibility and sustainability • Resources and Tools are shared cross- disciplinarily • Enable Service-Oriented Science • “scientific research enabled by distributed networks of interoperating services” • New e-Infrastructure is required to host both the data and services 6
Distributed Computing Infrastructure for e-Science • Enabling collaboration to realize that the whole is grater than the sum of parts • WWG realized the global e-Infrastructure to share resources over Internet • Cloud offers versatile granularity and new usage patterns to the DCI services • Granularity: service-oriented layers in infrastructure, platform, software, data, network, etc. • Usage pattern: on-demand elasticity • More user customized and user controlled environment on remote Mário Campolargo European Commission - DG INFSO – resources OGF 23, Barcelona June 2008 7
The Grid • “a software infrastructure that enables flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources”. • Foster, Kesselman and Tuecke • Features • No central control • Production quality • Open standards and open architecture 8
Data-Driven Multiscale Collaborations for Complexity Great Challenges of 21st Century ! Multiscale Collaborations • General Relativity, Particles, Geosciences, Bio, Social... • And all combinations... ! Science and Society being transformed by CI and Data • Completely new methodologies • “The End of Science” (as we know it) ! CI plays central role • No community can attack challenges • Technical, CS, social issues to solve ! Places requirements on computing, software, networks, *Small groups still important! tools, etc 9 Source: Ed Seidel � !"

From the Basic Grid Use Case • On behalf of an authorized user, " AAI and single sign on services for versatile IaaS, PaaS and SaaS. • Tools interrogate the information system, " resource discovery or dynamic provisioning • Locates an optimal execution resource, submits the job to the execution resource, which in turn interprets the submitted job description and locates and fetches the necessary input data from a remote storage - also on behalf of the user. • Resource on-demand provisioning model with customized application environment • Elastic and efficient resource matchmaking model according to user-defined metrics and requirements • Storage space and file system on-demand • Job overflow and scalable automatically • Upon the completion, the newly created data is uploaded to a storage resource where this user is authorized (as a member of a Virtual Organization), registered in the necessary data indexing catalogs, and the job record is updated in the accounting and monitoring system. • Support streaming and minimization congestion, avoid duplicate transmission, by P2P technology • Enhanced accounting and monitoring system • Network virtualization S!"
