  3. In the Future N G S UK Grid Operations Support Centre

  4. ETF NGS Other software sources Software with proven capability & realistic deployment experience OMII ‘Gold’ services Prototypes & specifications Feedback & future requirements GOSC • Core of GOSC built around experience in deploying and running National Grid Service (NGS) • Support service • Important to coordinate and integrate this with deployment and operations work in EGEE, LCG and similar projects. • EGEE – low level services, CA, GOC, CERT... • Dedicated deployment and operations management will be a key component UK Campus and other Grids EGEE… Operations Deployment/testing/advice

  5. GOSC Roles • Core UK Grid services: Simple Registry, data transfer, Job Submission, security, Data Access • Key services (to be supported for all Grids): Authorisation, Notification, Workflow, Monitoring and Accounting, Grid Management Services, VO support • Services to be coordinated with others (eg OMII, NeSC, LCG): Integration testing, compatibility & Validation Tests, User Management, training Timeline: May/June • Develop a roadmap for the development of the grid operations centre over the next two years June • Develop the GOSC proposal for next two years. • including deployment and support plans, interfaces to related projects and integration of non core resources into NGS, and criteria for service evaluation. September • Formal start of GOSC October • NGS “production service” • Compatibility with EGEE

  6. MPI, co-scheduling … Oxford and Leeds (White Rose Grid)

  7. Manchester and CCLRC-RAL

  8. Also includes: • http://www.csar.cfs.ac.uk/ • 256 Itanium2 processor SGI Altix • 512 processor Origin3800 http://www.hpcx.ac.uk/ Full installation = 1600 IBM p690+ Regatta processors currently 1236 processors EMBL Nucleotide Sequences NCBI, BLAST, EMBOSS, FASTA, Gaussian • Thus, the NGS provides access to over 2000 processors, over 36TB of "data-grid" • capacity, common scientific applications and extensive data archives. • Other resource providers anticipated to join in the future …

  9. NGS Status 28 May 2004 • All 4 cluster nodes operational • Announcement made on 5th April, to user communities in UK • “Pre-production” • ETF, NeSC, HPCx, and also via JISC web site • Common grid-mapfile for user management. • VOM server installation abandoned. • VOMS is now under review & installation by Grid Support Centre. • Information service operating using BDII infrastructure. • GridIce installation to give front end interface to BDII data. • GRidMon work to allow NGS monitoring, almost complete. • Federated Ganglia operational to allow centralised monitoring of resources and load across the four JISC/CCLRC sites.

  10. Ab Initio Molecular Orbital Theory eMaterials The DL_POLY Molecular Simulation Package What is Available?

  11. Users and Projects Users • 63 Users registered (excluding sysadmins etc…) • Leeds, Oxford, UCL, Cardiff, Southampton, Imperial, Liverpool, Sheffield, Cambridge, Edinburgh, QUB, BBSRC and CCLRC. Projects • e-Minerals • e-Materials • Orbital Dynamics of Satellite Galaxies (Oxford), • Bioinformatics (using BLAST), (John Owen BBSRC) • GEODISE project (Southampton) • Singlet meson project within the UKQCD collaboration (QCDGrid Liverpool + Edinburgh), • Census data analysis for geographical information systems (Sheffield) • MIAKT project (image registration for medical image anaylsis – Imperial) • e-HTPX project. • RealityGrid – Computational chemistry

  12. More than just computation and data resources… • In future will include services to facilitate collaborative (grid) computing • Authentication (PKI X509) • Job submission/batch service • Resource brokering • Authorisation • Virtual Organisation management • Certificate management • Information service • Data access/integration services (SRB/OGSA-DAI/DQPS) • National Registry (of registry’s) • Data replication • Data caching • Grid monitoring • Accounting

  13. NGS Resources • Free at the point of use (for UK e-Science) • Site contributions defined by Service Level Description • 4+2 core sites now • Cardiff and Bristol any day now • Anyone can join • Agree to the Base SLD • VDT (RB/VOM) … EGEE • Level of support/resource up to providers • Access conditions up to providers • Needs VO management and monitoring/accounting • Common core services

  14. Concluding Remarks • UK e-Science grid in pre-production mode • Goal is to provide national services • Not just access to storage + CPU • Likely to be a component of UK computing provision • Compatibility with EGEE,TeraGrid etc. important
