In the Future

N G S UK Grid Operations Support Centre Neil Geddes GridPP-10, June 2004

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 EGEE… Other software sources OMII ‘Gold’ services Prototypes & specifications ETF Software with proven capability & realistic deployment experience Feedback & future requirements NGS UK Campus Operations and other Grids Neil Geddes Deployment/testing/advice GridPP-10, June 2004

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 Neil Geddes GridPP-10, June 2004

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

Manchester and CCLRC-RAL

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 …

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.

What is Available?

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

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

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 Neil Geddes GridPP-10, June 2004

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 Neil Geddes GridPP-10, June 2004
