  1. Running applications on interoperable Grid infrastructures, focusing on OMII-UK supported software orHPC-BP Interoperability Tutorial OGF28, Munich s.crouch@omii.ac.uk Steve Crouch, David Wallom, MatteoTurilli, Morris Riedel, ShahbazMemon, Balazs Konya, Gabor Roczei, Peter Stefan, Andrew Grimshaw, Mark Morgan , Katzushige Saga, Justin Bradley, Richard Boardman

  2. Objectives • To give participants practical experience of: • Using individual middleware clients to submit jobs to HPC-BP compliant services • Using the HPC-BP interop demo framework, used for previous HPC-BP demos, to submit jobs to HPC-BP compliant services • To give participants opportunity (and starting point) to learn about: • Basic techniques and approaches for interoperability – what do I need, and how can I do this? • Some of the limitations of standards support across middlewares – what can’t I do?

  3. Tutorial Approach • ‘Presentation-lite’ • Learn at your own pace via online web tutorial… • …or follow my lead • Pragmatic • Generous in terms of time • Tutorial remains available after OGF28 • Ask for help!

  4. Schedule • Session 1: Using individual clients to invoke HPC-BP services • Overview of the demo + demo, Introduction to GridSAM • Download, Install and Configure GridSAM • Submit a Trivial Compute-only JSDL Job to HPC-BP Compliant Services • Download, Build and Configure the BES++ Client • Running the BES++ Client Against HPC-BP Compliant Services • Session 2: Using HPC-BP demo framework to invoke multiple HPC-BP services simultaneously • Download, Install and Configure the Demo Framework • Running the Demo Against Multiple HPC-BP Compliant Services • The Demo in Detail: Adding Another Endpoint to the Demo

  5. The Interoperability Demonstrator

  6. Background • Motivation: • Researchers are often reaching the limits of locally available resources to conduct research • They are beginning to realise the potential of using much larger-scale resources • Compute resources are becoming more numerous and available across Europe • However, using different Grid middleware deployments is traditionally difficult • Middleware clients for different deployments not compatible • Require different security policies/configuration for each

  7. Background • Possible solutions: • Maintain infrastructure that enables use of different clients for each middleware – interoperation • Not scalable - user learning curve, operation and maintenance • Each middleware supports a common service interface, enabled through adoption of accepted open standards – interoperability • Need only learn, use and maintain single client infrastructure • Still leaves security! • What can be practically achieved, in terms of interoperability, with middlewares that adopt OGF compute-related standards? • What is possible? • Limitations? • Demonstrate through proof-of-concept, client-side, application-focused demo

  8. History • Initiated by UK National Grid Service, OMII-UK and FZJ • Initially shown at OGF27, Banff, Canada, Oct 09 • SuperComputing, Nov 09 • ETSI Plugtests, FZJ, UK AHM, Dec 09 • GIN-CG, OGF28, Mar 10 • Demonstrators: David Wallom, Peter Stefan, Morris/ShahbazMemon, Steve Crouch Video available at http://www.omii.ac.uk/wiki/Videos

Future Work • Standards integration: • Integrate GENESIS II and SMOA Computing • Replacement of BES++ Client with SAGA • SAGA BES adapter currently in development! • Schedule across BES/non-BES endpoints (e.g. Globus) • GLUE2 (e.g. using OMII-UK Grimoires software) • Service discovery (static) • Dynamic allocation (dynamic) • Integrate CREAM-BES? • Security: ‘Static’ trust set up of security, proper VO set up? • Middleware client ‘audit’ of interoperability? • Leads to ability to configure and use different middleware HPC-BP clients… • Use of HARC for advance reservation • Clean up the code, upload to OGF Forge within GIN-CG • Participation very much an open process – if you wish to donate an HPC-BP compliant endpoint, please let me know!

  19. Future Direction • Interface: • Workflow engine integration • To replace/provide alternative to the Perl script • Taverna2 good candidate • Application abstraction • Use of endpoints: • Utilise production-level deployments • Utilise production-level security Future Utilise production-level deployments Verified/Increasing Interoperability Now Abstraction level
