T6. Deployment of LCG for creating Russian GRID segment

Task coordinator : V. Ilyin, belonging to team: SINP-MSU

Objectives :

Installation and test of the key LCG infrastructure components (Resource Broker, Information Service, etc.) in the Russian segment to achieve its full-scale functionality. This upgrading implies preserving full integration of the Russian GRID segment into the LCG infrastructure so that it will serve as a cluster at the Tier2 level.

Evaluation of the new technology based on Web Services Resource Framework (WSRF) considered as a candidate for further stages of LCG. Testingthe key components of LCG middleware in this new environment. Investigation of possibility for implementation of WSRF-compliant services at Russian LCG-segment.

Development of Russian LCG web portal (current prototype - http://lcg.jinr.ru) including: information support (current status of tasks, participants, sites, resources etc.); current resource usage and statistics; tools for integration of monitoring data in summary tables and graphical form.

Methodology :

The deployment of the key GRID components in Russian segment will be based on LCG middleware (EDG, GLOBUS, Condor, etc). Implementation of the components will be carried out in such a way that at every step to preserve functionality of the segment in order to match the requirements and obligations within the LCG project.

Available releases of WSRF-compliant middleware will be tested, compaed with OGSA-based Globus Tolkit 3 and evaluated. In the case of positive results, some services will be gradually deployed in Grid system within SINP-MSU, JINR and in Russian LCG-segment. The middleware is planned to be tested in several hosting environments, with different application servers and types of application problems.

Use of Web forms for giving monitoring information of GRID's, monitoring information from computing units and system, statistic information on utilized capacity and the resource usage. Developing of special software for collecting various information from heterogeneous systems. Storing the information in specialized databases.

Objectives :

The Russian LCG segment is currently being joined to LCG-1 as a set of sites (institutes). From the beginning of 2004, in the framework of the current project, we plan to install and test the key infrastructure components, such as the Resource Broker, Resource Information Service, etc., in order to achieve its full-scale functionality. This upgrading implies preserving full integration of the Russian GRID segment into the LCG infrastructure so that it will serve as a cluster at the Tier2 level.

Methodology :

The deployment of the key GRID components in Russian segment will be based on LCG middleware (EDG, GLOBUS, Condor, etc). Implementation of the components will be carried out in such a way that at every step to preserve functionality of the segment in order to match the requirements and obligations within the LCG project.

T6.2. OGSA/Globus evaluation for data intensive applications

Subtask coordinator : A. Demichev, belonging to team: SINP-MSU

Other participants: L. Shamardin and V. Kalyaev (SINP-MSU), V. Pose (JINR), M. Lamanna (CERN IT)

Objectives :

It is widely expected that future architecture of Grid systems will be more clearly aligned with the general evolution of Web services (WS) and will integrate more effectively with WS standards. Currently, a basis for such an evolution of the Grid is provided by the WS-Resource Framework (WSRF; http://www.globus.org/wsrf). The WS-Resource Framework was inspired by the preceding work on the Open Grid Service Architecture/Infrastructure (OGSA/OGSI). Our task will be an evaluation of this new technology considered as a candidate for the further stages of LCG. In particular, we shall study the WSRF-based releases of Globus Toolkit (GT), the first such release (GT4.0-beta) being scheduled by the Globus Alliance and IBM for June 2004. Then we intend to study a possibility for implementation of WSRF-compliant GRID services in the Tier2-structure of the Russian segment.

Methodology :

At the preliminary stage, the latest OGSA-based version of the Globus Toolkit (GT3.2) will be tested to have a reference point for further comparison with the WSRF-based versions of the middleware. A preliminary study of WSRF-based GT-releases will be carried out at PCs in CERN, JINR and SINP MSU. The middleware is planned to be tested in several hosting environments, with different application servers and types of application problems. In the case of successful results of the tests, some WSRF-compliant services may be gradually implemented in a Grid segments within SINP-MSU and JINR. We shall use the link Russia-CERN and personal visits for communications with IT team.
