1. Grid Computing at PSNC Jarosław Nabrzyski Poznań Supercomputing and Networking Center (PSNC) and Information Sciences Institute, Poznan University of Technology email: naber@man.poznan.pl www.GridLab.org

2. Talk Outline What is Grid Computing about? Background - Polish Information Infrastructure PIONIER Program Poznan Supercomputing and Networking Center PSNC’s Grid Research International collaboration IST projects The future (6FP)

3. The Grid Problem Flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources From “The Anatomy of the Grid: Enabling Scalable Virtual Organizations” Enable communities (“virtual organizations”) to share geographically distributed resources as they pursue common goals -- assuming the absence of… central location, central control, omniscience, trust relationships.

4. The Grid - Not a New Idea Late 70’s – Networked operating systems Late 80’s – Distributed operating systems Early 90’s – Heterogeneous computing Mid of 90’ - metacomputing (C.C. Catlett and L. Smarr) Transparent access to heterogeneous and geographically distributed computational resources, Giving a user access to the required computing power Metacomputing -> then the Grid: 1999, C. Kesselman and I. Foster

5. How are Grids Different? Autonomy Heterogeneity Focus on the user These three differences create many of the problems but also make the system much more usable than its predecessors

6. Elements of the Problem Resource sharing Computers, storage, sensors, networks, … Sharing always conditional: issues of trust, policy, negotiation, payment, … Coordinated problem solving Beyond client-server: distributed data analysis, computation, collaboration, … Multi-institutional virtual orgs Community overlays on classic org structures Large or small, static or dynamic

15. Grand Challenge Applications Black hole simulations, Gravitational wave detection, Other generic applications.

16. GridLab Aims Get Computational Scientists using the “Grid” and Grid services for real, everyday, production work (AEI Relativists, EU Network, Grav Wave Data Analysis, Cactus User Community). Make it easier for applications to make flexible, efficient, robust, use of the resources available to their virtual organizations. Dream up, prototype, and test new application scenarios which make adaptive, dynamic, wild, and futuristic uses of resources.

17. Solution “Grid Application Toolkit” or GAT Provides a layer between applications and emerging grid technologies. Provides an application developer orientated API, allowing the flexible use of different tools and services, as well as providing protection from developing software. “GridLab Testbed/VO” Diverse controllable environment for developing and testing applications and tools, software maintained by people who know it. End Users GAT Tool Developers Grid Infrastructure Developers GAT-API Developers

18. What GridLab Isn’t … Don’t want to develop low level Grid Infrastructure Don’t want to repeat work which has already been done (want to incorporate and assimilate it … Globus APIs, OGSA, ASC Portal (GridSphere/Orbiter), GPDK, GridPort, DataGrid, GriPhyn)

19. Architektura GridLab

20. Grid Scenario We see something, but too weak. Please simulate to enhance signal! WashU Potsdam Thessaloniki OK! Resource Estimator Says need 5TB, 2TF. Where can I do this? RZG NCSA 1Tbit/sec Hong Kong Resource Broker: LANL is best match… Resource Broker: NCSA + Garching OK, but need 10Gbit/sec… LANL Now.. LANL

21. Workpackages WP1: Grid Application Toolkit (AEI) This is a key component of GridLab - link between Grid middleware and applications, usable by any conforming application or middleware component. Requiring input from, and connecting to, most other workpackages and components. WP2: Cactus Grid Application Toolkit (AEI) Provides an extended GAT interface for Cactus, a very general toolkit framework supporting different Grid applications, from astrophysics to chemical engineering. Cactus will be one of the primary application drivers for the GAT, and the project generally. WP3: Work-flow Application Toolkit (CARDIFF) Will develop Grid capabilities for a widely used dataflow programming environment, Triana, used in gravitational wave and other data analysis areas.

22. Workpackages (cont.) WP4: Grid Portals (AEI) Will be highly application driven, aimed at providing uniform, flexible and intuitive user access to Grid resources from anywhere, as well as administration tools for maintaining a Grid environment. WP5: Testbed management (MU) Will administrate and maintain an active development testbed across roughly a dozen EU sites (leveraging the work of the EGrid), deploying technologies as they are developed by the project. This workpackage will also coordinate with sites in the USA-based NCSA Alliance and others to test and develop interoperability. WP6: Security (PSNC) Will develop the required security mechanisms and will ensure the integration of all the technologies developed under other WPs, taking into account the various local security requirements and state of the art solutions.

23. Workpackages (cont.) WP7: Adaptive Application Components (VU) develops a set of components and APIs to be plugged into the toolkit, for example to take monitoring information and implement basic techniques for short-term forecasting and behavior adaptation/optimization. WP8: Data Handling and Visualization (ZIB) will provide Grid aware techniques for data management, analysis, and visualization, needed especially for applications that make use of multiple sites in a dynamic, time dependent manner, leaving data unpredictably scattered across the Grid. WP9: Resource Management (PSNC) will develop resource need estimators, resource brokers, and other tools, for both Grid users and the applications themselves to make intelligent decisions about which Grid resources should be used at any instant in the lifetime of a simulation.

24. Workpackages (cont.) WP10: Information Services (ISUFI) will extend existing Grid middleware toolkits with dynamic features needed by applications to select appropriate Grid resources and to provide simulation information to collaborative user groups. WP11: Monitoring (SZTAKI) will develop new components that will fit in the general Grid monitoring architecture to support application steering, adaptive monitoring, and automatic analysis and prediction of performance data. WP12: Access for mobile users (PSNC, ZIB) will develop and test Grid access and monitoring technologies through a variety of mobile devices,

25. Workpackages (cont.) WP13: Information Dissemination and Exploitation (PSNC) will ensure the active dissemination of the project results through a variety of channels, including active participation in international organizations (e.g. GGF), co-development with other Grid projects in the USA and EU, participation in international conferences, training programs, instruction of GridLab technologies into various communities, and introduction into the commercial vendor world. WP14: Project Management (PSNC) day-to-day scientific, financial and administrative management of the project, including careful orchestration and monitoring of work across groups, major project decisions, liaisons with external projects and with the international advisory board, reporting

26. 6FP, Grids and PSNC Europe needs the Distributed EU-wide Supercomputing Facility, PSNC (and others) has already started to promote this idea, EoI in preparation, Strong co-operation with colleagues from UK, Project proposal (70-100 MEuro) in preparation

27. Computational Needs not Met Great scientific and engineering talent in EU Many EU programs now beginning, with training mission, but: No EU-wide facilities No Collaborative Infrastructure No HPC Training (except for do-it-yourself) Rely on US connections What do others do?? In many cases, they do toy problems EU science and engineering fall behind Germany, UK, France are slight exceptions, but no large scale Many countries (mainly NAS, but not only) simply cut off from modern science

28. Our Vision for the EU Facility Science and Engineering Drivers Expertise Centers (CFD, Astrophysics, Computational Biology, Aerospace, etc.) Sheparding/building communities across Europe Present science/engineering calculations require TB/Tflop/sec, but just scratching the surface! Need much more! Enabling new science Computational Science Drivers Need Grid Software infrastructure Cycles, networks, visualization centers Partnerships with existing centers, networks, etc

29. Vision of the Facility Distributed Nature Pushes networking technologies through apps Works to integrate European efforts, scientific, cultural, etc. East and West at 100Gb/sec! Multi-lambda backplane (GEANT?) Unique EU facility in the HPC world Leapfrog Teragrid with Big Machine, but also Draw on unique, more diverse EU research strengths Beginning of a Worldwide Grid Effort Unique challenges to integrating diverse EU grids Already strong support from US, NSF, DOE principals Scientists/engineers know they have expanding facility over coming decades (can affect their projects)

30. Our Vision Major Center Satellite
