6 EGEE What do we deliver? Infrastructure operation Currently includes ~200 sites across 40 countries Continuous monitoring of grid services & automated site configuration/management Middleware Production quality middleware distributed under business friendly open source licence User Support - Managed process from first contact through to production usage Training Expertise in grid-enabling applications Online helpdesk Networking events (User Forum, Conferences etc.) Interoperability Expanding geographical reach and interoperability with collaborating e-infrastructures BEGrid Seminar, Brussels - October 27,

7 Middleware Layers Enabling Grids for E-sciencE Applications Higher-Level Grid Services Workload Management Replica Management Visualization Workflow Grid Economies... Foundation Grid Middleware Security model and Infrastructure Computing (CE) and Storage Elements (SE) Accounting Information and Monitoring Applications have access both to Higher-level Grid Services and to Foundation Grid Middleware Higher-Level Grid Services are helping the users building their computing infrastructure but should not be mandatory Foundation Grid Middleware is deployed on the EGEE infrastructure Must be complete and robust Should allow interoperation with other major grid infrastructures Should not assume the use of Higher-Level Grid Services BEGrid Seminar, Brussels - October 27,

8 The glite Middleware Approach Exploit experience and existing components from VDT (Condor, Globus), EDG/LCG, and others glite is a distribution that combines components from many different providers! Develop, Test, Certify & Distribute a generic middleware stack useful to EGEE (and other) applications Pluggable components Follow SOA approach, WS-I compliant where possible Focus is on re-engineering and hardening Business friendly open source license Plan to switch to Apache-2 BEGrid Seminar, Brussels - October 27,

10 Grid Foundation: Computing Element Enabling Grids for E-sciencE The CE accepts batch jobs (and job control requests) through a gatekeeper, performs AAA, passes them to a LRMS, monitors the their execution and return results to the submitter WMS, Clients Information System Three flavours available now: LCG-CE (GT2 GRAM) in production now but will be phased-out by the end of the year glite-ce (GSI-enabled Condor-C) already deployed but still needs thorough testing and tuning. CREAM (WS-I based interface) Contribution to the OGF-BES group for a standard WS-I based CE interface Grid Site Computing Element glexec + LCAS/ LCMAPS bdii R-GMA CEMon BLAH BLAH is the interface to the local resource manager (via plug-ins) CREAM and glite-ce Information pass-through: pass parameters to the LRMS to help job scheduling WN LRMS BEGrid Seminar, Brussels - October 27,

11 Grid Foundation: Storage Element Site File Name (SFN): identifies a Storage Element and the logical name of the file inside it Physical File Name (PFN): argument of file open Storage Resource Manager (SRM) hides the storage system implementation (disk or active tape) checks the access rights to the storage system and the files translates SFNs to PFNs disk-based: DPM, dcache; tape-based: Castor, dcache File I/O: posix-like access from local nodes or the grid GFAL BEGrid Seminar, Brussels - October 27,

12 Example: The Disk Pool Manager Light-weight disk-based Storage Element Easy to install, configure, manage and to join or remove resources Integrated security (authentication/authorization) based on VOMS groups and roles All control and I/O services have security built-in: GSI or Kerberos 5 SRMv1 and SRMv2.1 interfaces. SRMv2.2 being added now Grid Client Data Server Name Server RFIO Client RFIO Daemon Disk System NS Daemon NS Database Gridftp Client SRM Client Gridftp Server RFIO Client SRM Server SRM Daemon Disk Pool Manager Request Daemon DPM Daemon DPM Database BEGrid Seminar, Brussels - October 27,

13 Grid Foundation: Accounting Enabling Grids for E-sciencE Resource usage by VO, group or single user Resource metering: sensors running on resources to determine usage Pricing policies: associate a cost to resource usage if enabled allowed marketbased resource brokering privacy: access to accounting data granted only to authorized people (user, provider, VO manager) Basic functionality in APEL, full functionality in DGAS BEGrid Seminar, Brussels - October 27,

14 High Level Services: Job Information Enabling Grids for E-sciencE Logging and Bookkeeping service Tracks jobs during their lifetime (in terms of events) Job Provenance stores long term job information Supports job rerun BEGrid Seminar, Brussels - October 27,

15 High Level Services: Workload Management Enabling Grids for E-sciencE Resource brokering, workflow management, I/O data management Î Web Service interface: WMProxy Task Queue: keep non matched jobs Information SuperMarket: optimized cache of information system Match Maker: assigns jobs to resources according to user requirements Job submission & monitoring ÎCondor-G ÎCondor-C ÎICE (to CREAM) External interactions: Information System Data Catalogs Logging&Bookkeeping Policy Management system (G-PBox) BEGrid Seminar, Brussels - October 27,

16 High Level Services : FTS Reliable and manageable File Transfer System for VOs Transfers are treated as jobs May be split onto multiple channels Channels are point-to-point or catch-all (only one end fixed). More flexible channel definitions on the way... New features that will be available in production soon: Cleaner error reporting and service monitoring interfaces Proxy renewal and delegation SRMv2.2 support Longer term development: Optimized SRM interaction split preparation from transfer Better service management controls Notification of finished jobs Pre-staging tape support Catalog & VO plug-ins framework Allow catalog registration as part of transfer workflow BEGrid Seminar, Brussels - October 27,

17 Encrypted Data Storage encrypt and decrypt data on-the-fly Key-store: Hydra N instances: at least M (<N) need to be available for decryption fault tolerance and security High Level Services: EDS Will be DPM (now d-cache) Will be LFC Demonstrated with the SRM- DICOM demo at EGEE Pisa conference (Oct 05) Will be GFAL BEGrid Seminar, Brussels - October 27,

18 Main focus for the developers Give support on the production infrastructure (GGUS, 2 nd line support) Fix defects found on the production software Support SL(C)4 and 64bit architectures (x86-64 first) Participate to Task Forces together with applications and site experts and improve scalability Improve robustness and usability (efficiency, error reporting,...) Address requests for functionality improvements from users, site administrators, etc... (through the Technical Coordination Group) Improve adherence to international standards and interoperability with other infrastructures Deploy and expose to users new components on the preview testbed Interoperability with Shibboleth Work plans available at: BEGrid Seminar, Brussels - October 27,

28 Why Sustainability? Scientific applications start to depend on Grid infrastructures e.g. EGEE supports well Sep. over 100 VOs, running over jobs/day Require long-term support Jobs/month Jan-05 Feb-05 Mar-05 Apr-05 May-05 Jun-05 Jul-05 Aug-05 Sep-05 EGEE workload Oct-05 Nov-05 Dec-05 Jan-06 Feb-06 Mar-06 Apr-06 Jan. 06 May-06 New scientific collaborations have been formed thanks to the Grid infrastructure E.g. WISDOM ( Business and Industry are getting very interested but need a long term perspective E.g. over 20 companies were present at the Business Track during the EGEE 06 conference, September, 2006 Jun-06 Jul-06 Aug-06 other VOs ops >50k jobs/day magic lhcb geant4 Virtual Organizations planck fusion esr egrid egeode dteam compchem cms biomed atlas alice BEGrid Seminar, Brussels - October 27,
