  1. Next Steps Mike Minetermjm@nesc.ac.uk

  2. Acknowledgements • Most slides are from GOSC / NGS: • Stephen Pickles • Neil Geddes • Andy Richards

  3. Goal of talk • Thus far the emphasis has been on what the NGS is, and how to use its core services. • The goal of this talk is to ensure that intending users of the NGS know what support services and procedures are provided by GOSC.

  4. Overview • Story so far • The Grid Operations Support Centre • Joining the NGS • More training??! • Information sources

  5. The story so far • The National Grid Service is providing a production service • It is a developing, dynamic service! • Core services in place: data, computation, portal • New middleware en route • More sites joining • International perspectives – EGEE, Teragrid • Grid Operations Support Centre is poised to help you…

  6. GOSC The Grid Operations Support Centre is a distributed “virtual centre” providing deployment and operations support for the UK e-Science programme.

  7. Steering Committee USERS Audit Board Director GOSC Management Board Development Manager Operations Manager/ Technical Director TRAINING Operations Board Operations Board ETF GSC GOC NGS Security Networking

  8. GOSC Roles • UK Grid Services • National Services • Authentication, authorization, certificate management, VO management, security, network monitoring, help desk + support centre. • support@grid-support.ac.uk • NGS Services • Job submission, data transfer, data access and integration, resource brokering, monitoring, grid management services, operations centre,… • NGS core-node Services • CPU, (meta-) data storage, key software • Services coordinated with others (eg OMII, NeSC, LCG): • Integration testing, compatibility & Validation Tests, User Management, training • Administration: • Policies and acceptable use conditions • Resource providers: service level agreements,… • Coordinate deployment and Operations

  9. Access Grid Certification Condor ETF For Information General GT2 GT3 GT4 Globus-MDS GridFTP Internal Maillist Myproxy NGS OGSA-DAI Project Registration RA Security SRB Support Notices Training Unicore

  10. Joining the NGS • As • Users • Projects (VO’s) • Resource providers

  11. End-users: what to do • You need a current UK e-Science Certificate • http://ca.grid-support.ac.uk/ • See your local Registration Authority • Complete the application form on the NGS web site, and read the conditions of use: • http://www.ngs.ac.uk/apply.html • Wait 1-2 weeks for peer review • You gain access to all core nodes automatically (incl SRB) • Contact GOSC to gain access to OGSA-DAI and Oracle • Use the NGS and GSC web sites and help-desk • Happy computing!

  12. User Registration (Process) Accepted (User Notified) User Applies (Via Website) User added to NGS VO (includes SRB account) Application QC Application Submitted to Peer Review Panel User added NGS-USER and NGS-ANNOUNCE Mailing lists Approved ? Rejected (User Notified)

  13. Projects and VOs • Just need access to compute and data resources for users in your project? • Currently, mainly applications from individuals • project-based applications being dealt with case-by-case, as procedures are established • if in doubt, talk to us! • Want to host your data on NGS? • consider GridFTP, SRB, Oracle, or OGSA-DAI • NGS maintains infrastructure • you populate and manage data • Want to use NGS resources to provision services, portals for a community of users? • next slide

  14. Providing services for a VO • NGS resources can be used to provide a portal (or portlets) or other service for your community • Deployment and security scenarios are negotiable • NGS policies (core nodes): • your portal can present its own, or a delegated user’s credential to NGS, but tasks should be traceable to initiating end-user • you should not run your own services in user space without prior agreement of NGS and hosting site • we need to know that services are secure, will not jeopardise operation of other NGS services, or consume too much precious resource on head nodes • Talk to GOSC!

  15. Commercial Provider UofD PSRE Leeds Man. RAL Oxford NGS Partner Sites: Integrated with NGS, some services/resources available for all VOs Monitored interfaces + services NGS Core Nodes: Host core services, coordinate integration, deployment and support +free to access resources for all VOs. Monitored interfaces + services NGS Affiliated Sites: Integrated with NGS, support for some VO’s Monitored interfaces (+security etc.) Resource providers GOSC U of C U of A H P C x U of B C S A R

  16. Resource providers Resource providers join the NGS by • Defining level of service commitments • Adopting NGS acceptable use and security policies • Run compatible middleware • as defined by NGS Minimum Software Stack • and verified by compliance test suite • Support monitoring and accounting Two levels of membership • Affiliates run compatible stack, integrated support • Partners also contribute “significant resources”

  17. Affiliation Affiliates commit to: • running NGS-compatible middleware • as defined in NGS Minimum Software Stack • this means users of affiliate’s resources can access these using same client tools they use to access NGS • a well-defined level of service and problem referral mechanisms • SLD approved by NGS Management Board and published on NGS web-site • providing technical, administrative, and security (CERT) contacts • providing an account and mapping for daily compliance tests (GITS++) • accepting UK e-Science certificates • maintaining baseline of logs to assist problem resolution

  18. Partnership Partners commit to same as affiliates, plus: • making “significant” resources available to NGS users • creation of accounts/mappings • in future, VO support, pool accounts, etc • recognise additional CAs with which UK e-Science programme has reciprocal agreements • publish/provide additional information to support resource discovery, brokering • ability to compile code for computational resources Bristol and Cardiff going through certification process now. • supported by “buddies” and NGS-Rollout list • useful feedback on viability of NGS Minimum Software Stack

  19. More training? • Watch http://www.nesc.ac.uk/training • Also • Globus Week, NeSC : 4-8 April via http://www.nesc.ac.uk/esi/esi.html • http://egee.nesc.ac.uk/ for EGEE events and materials – repository. • TELL US WHAT YOU WANT !!!! • In future versions of this course • In application developer courses • …..

  20. NeSC UK Training • Establishing set of core courses: • Induction, sysadmin, application devel.,… • For EGEE (current and gLite), NGS • Cooperating with OMII • Fundamentals: WS, WS-RF • In NeSC national role: • Building collaborations to support/co-deliver training with UK e-science centres and VO’s • Establishing repository and websitehttp://www.nesc.ac.uk/training • In NeSC’s regional role, providing: • events in Scotland • Training and support for potential & current users of grids

  24. And finally….

  25. The NGS • Is providing a production service • Currently has core resources, procedures and operations in place • Is developing and expanding • Both organisationally and in middleware • Is a “SERVICE” • Organised to respond to your requirements!!! • What do YOU want of the NGS? • Tell GOSC ! • GOSC: exists to support you!!!

  26. Last chance for questions… and feedback.

  27. Background slides

  28. NGS- Production service • Operating a production grid means valuing robustness and reliability over fashion. • NGS cares about: • alignment/compatibility with leading international Grid efforts • special requirements of UK e-Science community • easy migration/upgrade paths • proven robustness/reliability • based on standards or standards-track specifications • NGS cannot support everything • Everyone wants service-oriented grids • but still settling out: WS-I, WS-I+, OGSI, WSRF, GT3, GT4, gLite • Caution over OGSI/WSRF has led to wide convergence on GT2 for production grids and hence some inter-Grid compatibility
