OMII Roadmap Standards Future Managed Programme Software Repository International involvement


The OMII in a nutshell Open Middleware Infrastructure Institute Established January 2004, initially 3 years with

£6.5m Intention - To capitalise on existing e-science

investment and produce high-quality, reusable grid middleware

Rationale – much e-science invest in “proof of concept” and demonstrators – investigations into technology and approaches

OMII should benefit from, re-use, reengineer, existing e-science work where appropriate


The OMII Remit Key Goal is to produce usable and “used” grid middleware

and services. Achieved through: OMII “In-house” development Explicit S/W Contracts OMII “managed programme”

Success Criteria Number of software downloads Number of deployed systems Key academic and e-science projects use it Industry uptake

Sustained through success UK research, JISC and DTI funding Industry support


The OMII at Southampton Located on Southampton University Campus

– dedicated, continuous open plan offices Currently 13 F/T staff, recruiting additional 4

to 6 Additional continuous space allocated in

December


OMII_1 Product Overview OMII_1 is a secure infrastructure that enables collaboration

between users (clients) and providers of resource and applications Target Audience

Grid resource users: User requesting services/resources through a command line interface or through application

Service providers: Exposes resources or applications to known clients/users

Application developers: Web-service developers who want to provide distributed, controlled and secure access to their applications


OMII_1 Product Overview (2) Security

X509 Authentication (AAA) with HTTPS message security Authorisation through account based system at service providers

(AAA) Accounting (AAA) for resource/service use maintained by service

provider and visible to client. Accounting can influence Authorisation

Client/Service-provider Interaction Client submits resource request to service provider(s) Service provider(s) respond with a “quote” for job if the resource

provider can meet required constraints and client account has sufficient credit

Client selects a provider and submits job Client account is debited with estimated resources used for job On job completion client account is updated to actual resources

used


OMII_1 Product Components – (1) 4 packages Package 1 - Client download

Command line client and Java library to interact with any OMII_1 service provider

< 10 minutes to install and interact with servers at OMII

Example client application program Supported on Windows and SUSE9 Linux No additional download for Grid “Users”


OMII_1 Product Components –(2) Package 2 - OMII_1 Base and Extensions

Server base providing Tomcat, Axis and WS-Security < 10 minutes for complete install Supported on SUSE9 Linux

Package 3 - OMII_1 Services Initial basic services (Accounting service, resource Allocation

Service, Data movement service, Job Submission service) Installed on Base and Extensions (SUSE9 Linux)

Package 4 - OMII_1 Applications Sample application to demonstrate service provision Installed on OMII_1 Services Supported on Windows and SUSE9 Linux

Service Providers require Packages 2 and 3 Application developers require all packages


OMII_1 Associated Products OGSA-DAI Condor Interface PBS Interface


OMII_1 Product License All OMII code distributed using BSD license Includes licensed components (Apache

license and LGPL)


OMII_1 Release Timetable

Private pre-release OMII_1

Public pre-release OMII_1

Official OMII_1 release

Developers refresh

October 4th 2004

October 25th 2004

December 6th 2004

End Jan 2005

Pre-releases targeted at early adopters to grid enable services Little change from OMII_1 pre-release to official release

improved documentation, testing, platform support Developers Refresh

Refresh base and services Update WS-Security in line with WS-I Re-factor extensions to base to allow selective install of services


OMII_1 Customers Target E-science projects just starting

EPSRC projects in discussion – Integrative Biology, GOLD BBSRC project possibilities – ComparaGRID, GridQTL, e-Fungi, ISPIDER,

etc NERC, MRC, etc…

Existing E-science projects Follow-on e-science projects MyGrid Nerc DataGrid E-materials project ServerGrid project Astrogrid – already use web services and OGSA-DAI

Projects requiring a ready to use grid infrastructure including documentation, training courses, support

Industrial Partners Managed programme partners


OMII Roadmap - Position statement Committed to WS-I+

WS-I basic profile (SOAP, WSDL, UDDI) WS-I basic security profile (WS-Security) WS-Addressing, BPEL+, WS-Reliable

Messaging/WS-Reliability Plans and timescales to deliver WS-I+ OMII intends to adopt WSRF as and when

standardised and stable


OMII Product Roadmap 2005 April 2005: 2nd OMII Distribution

Include WS-Addressing Interoperability with GT4 New services


OMII Service Sets Roadmap In priority order, not

delivery order Delivery dependent on

managed programme

Basic Service Set Job Submit File movement Database Access Authorisation

Service Set 1 Workflow Registry Logging Accounting Session Management

Service Set 2 Notification Reliable Messaging File management services

(provenance, metadata, replica)


Delivering OMII service sets All OMII distributions will contain the basic

service set. Basic Service set will be revised & updated

between distributions Delivery of service sets 1 and 2 are post April

2005, although some services from service set 1 will be in OMII Distribution 2

Service sets are subject to modification


Managed Programme funding 2/3rds managed programme funding spent Projects funded:

OGSA-DAI (Database service) JDML (Job submit service) BPEL (Workflow service) Grimoires (Registry service) FIRMS (Reliable messaging) FINS (Notification) GeodiseLab (Matlab toolbox) WSRF:lite integration

Further contracts placed/calls in the next 6 months to address gaps

Basic Service Set

Service Sets 1 & 2


Managed programme status All projects required to engage 3 test communities

and use OMII distribution from outset Work negotiations complete

Grid SAM and Geodise started 1st September All others started in October

Official kick-off meeting 21st October in Southampton Introduction/discussion on OMII distribution and integration

of managed programme output Standards, Documentation, OMII security,…


External Contributions to OMII Major source through contracts and managed

programme Primarily contributing to essential elements of OMII

distributions Managed programme required to liaise with other

middleware bodies (e.g., EGEE, Globus) Additional source from repository contributions

Primarily end user services from e-science projects Generic service useful to others tested with OMII

distribution that are optional to install Talk to OMII – we can help publicise your services and

assist where appropriate with input to the repository


International Relationships with other infrastructure providers-NMI

Visited Condor group in June – identified 3 phases in collaboration OMII to use same test harness as NMI Link the OMII and NMI testing infrastructures Work with NMI to develop distributed testing framework

Status Regular conference calls A non-interactive version of the OMII distribution is being

integrated into the NMI build system Demonstration of OMII build in NMI scheduled for SC2004


International Infrastructure Relationships (2) EGEE

Specific integration with managed programme projects (Registry, Grid SAM)

Further integration and interoperability to be investigated Q4 2004

Globus Visited Globus June - discussed integration possibilites

Security – possible re-use of SAML/PERMIS infrastructure from GT4 – common core with EGEE/GT4

Integration of GRIDFTP (dependent on delegation service) Joint requirements gathering


International Relationships with Standards Organisations (3)

GGF Indirect through managed programme – JSDL

working group, GRID SAM; SAGA working group, Geodise Lab

Requirements gathering presented last GGF EGA

Member through core programme – no active communication

Oasis member


OMII International Profile We are expected to engage with the community

standards, specifications, working with other people who are trying to achieve the same goal.

OMII will take the lead on infrastructure integration OMII is working directly with NMI on Testing Globus and EGEE on integration at the level where

services can be invoked across infrastructures
