  • AcknowledgementsMost slides are from GOSC / NGS:Stephen PicklesNeil GeddesAndy Richards

  • Goal of talkThus 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.

  • OverviewStory so far

    The Grid Operations Support Centre

    Joining the NGS

    More training??!

    Information sources

  • The story so farThe National Grid Service is providing a production serviceIt is a developing, dynamic service!Core services in place: data, computation, portalNew middleware en routeMore sites joining International perspectives EGEE, TeragridGrid Operations Support Centre is poised to help you

  • GOSCThe Grid Operations Support Centre is a distributed virtual centre providing deployment and operations support for the UK e-Science programme.

  • GOSC RolesUK Grid ServicesNational ServicesAuthentication, authorization, certificate management, VO management, security, network monitoring, help desk + support NGS Services Job submission, data transfer, data access and integration, resource brokering, monitoring, grid management services, operations centre,NGS core-node ServicesCPU, (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

  • Joining the NGSAsUsersProjects (VOs)Resource providers

  • End-users: what to doYou need a current UK e-Science Certificate See your local Registration AuthorityComplete the application form on the NGS web site, and read the conditions of use: Wait 1-2 weeks for peer reviewYou gain access to all core nodes automatically (incl SRB)Contact GOSC to gain access to OGSA-DAI and OracleUse the NGS and GSC web sites and help-deskHappy computing!

  • User Registration (Process)User Applies(Via Website)Application Submitted to Peer Review PanelApplication QCApproved ?Rejected(User Notified)Accepted(User Notified)User added to NGS VO(includes SRB account)User added NGS-USER andNGS-ANNOUNCEMailing lists

  • Projects and VOsJust need access to compute and data resources for users in your project?Currently, mainly applications from individualsproject-based applications being dealt with case-by-case, as procedures are establishedif in doubt, talk to us!

    Want to host your data on NGS?consider GridFTP, SRB, Oracle, or OGSA-DAINGS maintains infrastructureyou populate and manage data

    Want to use NGS resources to provision services, portals for a community of users?next slide

  • Providing services for a VONGS resources can be used to provide a portal (or portlets) or other service for your communityDeployment and security scenarios are negotiableNGS policies (core nodes):your portal can present its own, or a delegated users credential to NGS, but tasks should be traceable to initiating end-useryou should not run your own services in user space without prior agreement of NGS and hosting sitewe need to know that services are secure, will not jeopardise operation of other NGS services, or consume too much precious resource on head nodesTalk to GOSC!

  • Resource providersResource providers join the NGS byDefining level of service commitments Adopting NGS acceptable use and security policiesRun compatible middlewareas defined by NGS Minimum Software Stackand verified by compliance test suiteSupport monitoring and accounting

    Two levels of membershipAffiliates run compatible stack, integrated supportPartners also contribute significant resources

  • AffiliationAffiliates commit to:running NGS-compatible middlewareas defined in NGS Minimum Software Stackthis means users of affiliates resources can access these using same client tools they use to access NGSa well-defined level of service and problem referral mechanismsSLD approved by NGS Management Board and published on NGS web-siteproviding technical, administrative, and security (CERT) contactsproviding an account and mapping for daily compliance tests (GITS++)accepting UK e-Science certificatesmaintaining baseline of logs to assist problem resolution

  • PartnershipPartners commit to same as affiliates, plus:making significant resources available to NGS userscreation of accounts/mappingsin future, VO support, pool accounts, etcrecognise additional CAs with which UK e-Science programme has reciprocal agreementspublish/provide additional information to support resource discovery, brokeringability to compile code for computational resources

    Bristol and Cardiff going through certification process now.supported by buddies and NGS-Rollout listuseful feedback on viability of NGS Minimum Software Stack

  • More training?Watch Week, NeSC : 4-8 April via for EGEE events and materials repository.

    TELL US WHAT YOU WANT !!!!In future versions of this courseIn application developer courses..

  • NeSC UK TrainingEstablishing set of core courses:Induction, sysadmin, application devel.,For EGEE (current and gLite), NGSCooperating with OMIIFundamentals: WS, WS-RFIn NeSC national role:Building collaborations to support/co-deliver training with UK e-science centres and VOsEstablishing repository and website NeSCs regional role, providing: events in ScotlandTraining and support for potential & current users of grids

  • And finally.

  • The NGSIs providing a production serviceCurrently has core resources, procedures and operations in placeIs developing and expandingBoth organisationally and in middlewareIs a SERVICEOrganised to respond to your requirements!!! What do YOU want of the NGS?Tell GOSC !GOSC: exists to support you!!!

  • Last chance for questions and feedback.

  • Background slides

  • NGS- Production serviceOperating a production grid means valuing robustness and reliability over fashion.NGS cares about:alignment/compatibility with leading international Grid effortsspecial requirements of UK e-Science communityeasy migration/upgrade pathsproven robustness/reliabilitybased on standards or standards-track specificationsNGS cannot support everythingEveryone wants service-oriented gridsbut still settling out: WS-I, WS-I+, OGSI, WSRF, GT3, GT4, gLiteCaution over OGSI/WSRF has led to wide convergence on GT2 for production grids and hence some inter-Grid compatibility

  • Certificate Authority

    User Registration Process

    Schematic overview of the user registration process including peer review process now in place.

    The process can take up to 7 days (maximum) during which time if no reject statements have been received from anyone on the peer review panel, then the user is accepted and granted an account and subscribed to the User related NGS mailing lists.

    (Note: SRB account is also automatically generated at this stage, but until we know the licensing issue then we are not making this publicly known!)
