  • Core NGS
  • VDT (Globus 2) Middleware
  • OGSA-DAI implementation (pre-production)
  • Data Services Oracle, SRB
  • Various Applications
  • GOSC GSC Supported services for the NGS
  • MyProxy Service myproxy.grid-support.ac.uk
  • BDII / MDS Information Service (Production and
    Development)
  • VOM (LCG-VO) Service
  • Monitoring tools
  • GOSC (GSC, NGS) Developing expertise with EGEE
    software / middleware
  • Test infrastructure exists to allow evaluation

NGS Software
6
NGS Database Service
  • Database Service on CCLRC RAL and Manchester
    Sites
  • Oracle 9i RAC (hold license for 10g if/when
    required)
  • Using OCFS
  • Oracle Application Server
  • 5 node Clustered Database
  • Single node Database for SRB
  • Use of Transparent Application Failover (TAF)

7
NGS SRB
  • Single instance Oracle 9i for MCAT at CCLRC
    RAL, duplicated at Manchester
  • SRB Version 3.2.1, using GSI authentication
    mechanisms
  • SRB vaults at each of the NGS core sites
  • Single NGS zone for core nodes
  • Option to use Federation for other zones.

Production Status
  • TODAY
  • 4 new core nodes operational
  • 123 Users registered (23 since 1 September 04)
  • Grid enabled Globus v2 (VDT distribution v1.2)
    at present
  • BDII information service (GLUE MDS Schemas)
  • Data Services Oracle and SRB
  • Growing base of user applications
  • MyProxy and CA services provided by UK Grid
    Support Centre
  • VO Management Software LCG-VO
  • User support Helpdesk
  • Next
  • Other Middleware gLite/OMII etc
  • NGS Portal
  • Resource Broker
  • SRB production service

18
Challenges
  • Defining the Service Computational and Data
    Services
  • Middleware ? EGEE/LCG? O/S Dependancy (RH7.3)
  • Integrating Helpdesk Support within UK Europe
    GGUS
  • Adding new sites (SLDs, monitoring)
  • Licensing (applications)
  • Getting people to use the Grid / Education
  • Making it easier to use better/easier client
    access for non-technical users

19
  • LCG2/EGEE0 Interested to see if makes
    installation easier
  • LCG2 not Enterprise Linux ready yet. (Redhat 7.3
    Officially)
  • Taking package gives additional items, free
    such as R-GMA
  • At Present
  • Use of BDII, use of GLUE schemas (not fully
    populated no fmon agents)
  • LCG VO Management software
  • For creating grid-mapfiles
  • For Portal access control
  • Resource Broker
  • Some successful tests against NGS nodes
  • Kevin?

20
  • Future
  • Use of gLite?
  • Other EGEE applications? VOMS?
  • EGEE/OMII Middleware others?
  • Aim
  • Ease of interaction between whatever grid for
    end users.
