Vision
“ e-Science having
easy access and use
of Grid resources
in heterogeneous
e-infrastructures
crossing national,
pan-European
and global boundaries “
EU project: RIO31844-OMII-EUROPE7
Mission
“ Enabling of
e-infrastructure
interoperability
by providing
standards-based
middleware components
leveraging existing work
and activities “
EU project: RIO31844-OMII-EUROPE8
Focus
• Achieving interoperability through common standards– Common standards is the long term solution– Significant involvement and success in OGF and
Oasis– Implementations of standards in tandem with
standards development on all middleware platforms
EU project: RIO31844-OMII-EUROPE9
Approaches to Interoperability
• Adapters-based:– The ability of Grid
middleware to interact via adapters that translate the specific design aspects from one domain to another
• Standard-based:– the native ability of Grid
middleware to interact directly via well-defined interfaces and common open standards
* definition inspired by OGF GIN CG
EU project: RIO31844-OMII-EUROPE10
Who Benefits from Interoperability?
• Grid Developers– A single standard set of services on all Grid middleware systems– Applications portable across different Grid middleware systems
• E-Science application users– Common ways for accessing any e-infrastructure resources– Potential access to a significantly larger set of resources
• E-resource owners– Reduced management overheads as only a single Grid
middleware system needs deployment– Potential for greater resource utilisation
“For the Grid to deliver on it’s promises interoperability needs to be taken for granted like network interoperability”
EU project: RIO31844-OMII-EUROPE11
Participation in Middleware Standardisation• Most project participants involved as member/observer in many OGF WG• 11 project participant hold senior positions in
– OGSA DAIS WG (Database Access and Integration Services)– OGSA RUS WG (Resource Usage Server)– OGSA BES WG (Basic Execution Service)– OGSA JSDL WG (Job Submission Description Language)– GIN CG (Grid Interoperability Now)– OGSA-AuthZ-WG (Authorization)– GLUE WG – GFSG WG (Grid File System)– RM WG (Reference Model)– OGSA Naming WG– Technical Standards Committee– GSA RG (Grid Scheduling Architecture)– GRAAP WG (Grid Research Agreement Allocation Protocol)– OGSA BYTE IO WG– OGSA D WG (Data)– OGSA DMI WG (Data Movement Interface)
EU project: RIO31844-OMII-EUROPE12
OMII-Europe Guiding Principles
• Committed to standards process– Implementing established open standards– Providing feedback to the standards process (e.g. OGF)
• Quality Assurance– Published methodology and compliance test– All software components have public QA process and audit trail
• Impartiality– OMII-Europe is “honest broker” providing impartial
advice/information on e-infrastructures

What OMII-Europe is Doing?
• Initial focus on providing common interfaces and integration of major Grid software infrastructures
• Common interoperable services:– Database Access– Virtual Organisation Management– Accounting– Job Submission and Job Monitoring
• Infrastructure integration– Initial gLite/UNICORE/Globus interoperability– Interoperable security framework– Access these infrastructure services through a portal
EU project: RIO31844-OMII-EUROPE15
Job Submission
• Unify Job Submisson and Monitoring interface
– Adoption of emerging OGSA-BES and JSDL standards
• Alpha BES and JSDL implementations for
– UNICORE 6, gLite 3.1, Globus 4, OMII-UK, CROWNgrid
• Interoperability demonstrated through use of a BES compliant meta-scheduler
EU project: RIO31844-OMII-EUROPE16
VO Management
• To provide a common Virtual Organisation (VO) management solution across middleware distributions
• Extend VOMS Interface to support emerging AuthZ standard– compliance with SAML
Authorisation model
• Extension, not a replacement interface
• Public release of VOMS integrated with UNICORE
EU project: RIO31844-OMII-EUROPE17
Accounting
• Unify accounting information across middleware distributions
• Provide standardized interfaces for accessing that information– Information standard:
• Usage Record Format (URF)
– Service interface standard:• Resource Usage Service
(OGSA-RUS)
• Alpha versions RUS – gLite (DGAS)– Globus (SGAS)– UNICORE
EU project: RIO31844-OMII-EUROPE18
Data Access
• Port OGSA-DAI 3.0 from Globus to other middleware distributions available throughout Europe and China– UNICORE– gLite– CROWN
EU project: RIO31844-OMII-EUROPE19
Portal
• Deliver tools for developing Grid portals and support for key Web and Grid standards and technologies
• Objectives:– Develop gateway to OMII
Evaluation Infrastructure– Develop tools for portal and
grid software training – Explore new approaches
for grid portal development
EU project: RIO31844-OMII-EUROPE20
Repository of Open-Source Software
• Make available software reengineered within OMII-Europe and contributed by third parties– Single services/tools & complete distributions
• Provide an interface to select software from the repository based on user requirements– By capability/standards/provider/…
• Support the upload, download and installation of the software– Document platform portability & pre-requisites
• Verify the software through compliance & metrics tests
EU project: RIO31844-OMII-EUROPE21
Behind the Repository
• Leverage existing infrastructure & projects– ETICS
• Capture build & test configuration data for repeatability
– NMI Build & Test Framework• Manage cross-platform environment for build & tests
– Condor• Underlying execution infrastructure
• Provides reports to be displayed within the portal– Builds: Pre-requisites & platforms– Testing: Conformance & Interoperability
EU project: RIO31844-OMII-EUROPE22
Tests For Standards Conformance
• Job Submission and Job Monitoring– Job Submission Description Language (JSDL)– Basic Execution Service (BES)
• Accounting – Usage Record (UR)– Resource Usage Service (RUS)
• Database Access– WS-DAI, WS-DAIX, WS-DAIR (OGSA-DAI)
• Virtual Organisation Management– Move towards SAML2?
EU project: RIO31844-OMII-EUROPE23
New Services Activity
• To identify capabilities which are missing from the OMII-Europe initial plans
• To identify priorities for the placement of such capabilities
• To work for the inclusion of the most relevant missing capability during the 2nd year of the project (May 2007-Apr 2008)
• To identify the challenges for further work
EU project: RIO31844-OMII-EUROPE24
The First Missing Piece:a Community-agreed Information Model for Computing Resources
• OGSA-BES and JSDL are already considered by OMII-Europe
• They lack a common description of Grid resources suitable for discovery, monitoring and scheduling
• Many descriptions exist– e.g.: GLUE Schema, NorduGrid Schema
• Working on the definition of next-generation GLUE Information Model in the context of OGF GLUE WG and its implementationIt
EU project: RIO31844-OMII-EUROPE25
What can you do Now… and Later…
• Now– Most products at Beta stage becoming publicly available– They provide basic interoperability of multiple grid middleware
systems focusing on job execution– Available to early adopters working with OMII-Europe partners
• Spring 2008 (end of current project)– Further security integration work between different middleware
platforms (SAML-VOMS, TLS (Transport level security))– Completed QA’d services and demonstrated end-to-end
solutions – Availability of GLUE 2 information model service implementations
EU project: RIO31844-OMII-EUROPE26
Summary (1/2)• OMII-Europe is a 24 Month EU funded project with 16 partners
to establish grid infrastructure interoperability through implementing a set of agreed open standards on all middleware platforms
• OMII-Europe is implementing a number of components that will allow identically specified jobs to be run, managed and migrated to different middleware platforms
• Initial versions of BES, VOMS/SAML and security service have already enabled UNICORE and gLite managed resources to be used by the same job
• A complete set of fully interoperable services will be available in spring 2008
EU project: RIO31844-OMII-EUROPE27
Summary (2/2)
• Users can try interoperability on the OMII-Europe evaluation infrastructure, or obtain services for installation on their own resources from the OMII-Europe repository
• We anticipate OMII-Europe services to be integrated into standard middleware distributions as well as deployed on large scale e-infrastructures such as EGEE and DEISA
• OMII-Europe requested continuing funding in the September EU call to support the existing services and provide further services in the areas of data and Grid management
