XD at a Glance Technical Audit Service develops lightweight tools (XDMoD) to enable stakeholders to obtain information on the systems, performance, usage and other characteristics of the XD resources – extremely valuable for data collection – Aid users, system administrators and NSF Program Director Technical Insertion Service evaluates software and middleware and makes recommendations for injection into project XSEDE provides the integrating services for the project: Coordination and management, advanced user services and training, education and outreach XSEDE is a comprehensive set of advanced heterogeneous high-end digital services, integrated into a general-purpose infrastructure. XSEDE is about increased user productivity, not just high end resources Increased productivity leads to more science at all levels Increased productivity is sometimes the difference between a feasible project and an impractical one

The Vision Enhance the productivity of scientists and engineers by providing them with new and innovative capabilities Facilitate scientific discovery while enabling transformational science/engineering and innovative educational programs Develop a more sustainable approach to the national CI

XSEDE supports a breadth of research Earthquake Science and Civil Engineering Molecular Dynamics Nanotechnology Plant Science Storm modeling Epidemiology Particle Physics Economic analysis of phone network patterns Brain science Analysis of large cosmological simulations DNA sequencing Computational Molecular Sciences Neutron Science International Collaboration in Cosmology and Plasma Physics Sampling of much larger set. Many examples are new to TeraGrid/HPC. Range from petascale to disjoint HTC, many are data driven. XSEDE will support thousands of projects. From direct contact with user community as part of requirements collections

XSEDE’s Distinguishing Characteristics Foundation for a national CI ecosystem – in sync with the NSF CIF21 vision A comprehensive suite of advanced digital services Federated with other high-end facilities, other providers of digital services here and abroad and importantly campus-based resources Unprecedented integration of diverse digital resources Developing an innovative, open architecture making possible the continuous addition of new technology capabilities and services – Achieve Seamless integration of resources at all levels

XSEDE: An Infrastructure Designed for Innovation & Evolution An environment in which all resources, data and services relevant to a researcher can be embedded and shared Campus bridging creating a single virtual system with interactive data transfer and resource sharing capabilities “make my data accessible everywhere I want to be” Coordinated archival approach to ensure persistence of important datasets beyond the lifetime of particular service providers – Still needs fleshing out An underlying infrastructure to support this Open architecture with judicious use of standards designed to evolve in a non-disruptive way Interoperability of XSEDE with other Cis – OSG, PRACE, DEISA NAREGI

XSEDE’s Distinguishing Characteristics - Architecture XSEDE is designed for innovation & evolution There is an architecture defined, but it is still evolving as a consequence of the review process based on set of design principles rooted in the judicious use of standards and best practices clearly defined transition plan from TeraGrid to XSEDE Professional systems engineering approach Responds to evolving needs of existing, emerging, and new communities incremental development/deployment model New requirements gathering processes ticket mining, focus groups, usability panels, shoulder surfing Ensure robustness and security while incorporating new and improved technologies and services Process control, quality assurance, baseline management, stakeholder involvement
10
How XSEDE describes the architecture A set of “views” examining the elephant from the perspectives of different stakeholders Not (only) immensely detailed documentation! Different stakeholders require different views, e.g., Service provider System administrator Power user Occasional user Gateway developer Tell us what views you think are important – Security officer – NSF program manager – Campus CIO – Trainer –...

XSEDE’s Distinguishing Characteristics - Governance World-class leadership from CI centers with deep experience: partnership led by NCSA, NICS, PSC, TACC and SDSC PI: John Towns, NCSA/Univ of Illinois Co-PIs: Jay Boisseau, TACC/Univ of Texas Austin Patricia Kovatch, NICS/Univ of Tenn-Knoxville Ralph Roskies, PSC/CMU Nancy Wilkins-Diehr, SDSC/UC-San Diego Partners who strongly complement these CI centers with expertise in science, engineering, technology and education Univ of Virginia Ohio Supercomputing Center SURACornell Indiana UnivPurdue Univ of Chicago Rice BerkeleyNCAR Shodor Jülich Supercomputing Centre
12
Engaging stakeholders Collection of stakeholder needs: surveys, ticket mining, … focus groups, usability panels, … interviews, shoulder surfing, … Prioritization of identified need and derived requirements User Requirements Evaluation and Prioritization (UREP) Working Group broad participation across architecture, deployment, operations, users, and service providers Assessing plans and deployments through a variety of stakeholder-focused, facilitated workshops e.g., interactive ATAM sessions focused on identifying, quantifying, discussing tradeoffs Representation in the management of XSEDE XSEDE Advisory Board User Advisory Committee Service Providers Forum
