  1. Grid computing for CBM at JINR/Dubna Ivanov V.V. Laboratory of Information Technologies, Joint Institute for Nuclear Research, Dubna, Russia CBM Collaboration meeting, GSI, Darmstadt 9-12 March, 2005

  2. Main directions of this activity includes: • Integration and shared use of informational and computational resources, distributed databases, electronic libraries. Realisation of the Dubna-Grid project. • Use of modern systems for storing and processing large-scale arrays of model and experimental data. • Possibility of remote participation of experts of the JINR Member States at the basic facilities of JINR. • Joint work on managing corporate networks, including the problems of control, analysis, protection of networks, servers, information. • Joint mastering and application of the Grid-technologies for physical experiments and participation in creation of national • Grid-segments. • Joint work on creation of distributed supercomputer applications.

  3. JINR telecommunication links

  4. JINR Gigabit Ethernet infrastructure (2003-2004)

  5. DLNP LIT Star-like logical topology of the JINR Gigabit Ethernet backbone with the Cisco Catalyst 6509 and Cisco Catalyst 3550 switches in the center of the core, and the Cisco Catalyst 3550 switches in 7 JINR divisions (in 6 Laboratories and in the JINR Administration), and Cisco Catalyst 3750 switch in LIT.

  6. In the year 2004: The network of Laboratory of Information Technologies was left as a part of the JINR backbone, meanwhile the rest JINR divisions (7) were isolated off backbone with their Catalyst 3550 switches. Controlled-access (Cisco PIX-525 firewall) at the entrance of the network.

  7. Characteristics of the network: • High-speed transport structure(1000 Mbit/sec); • Security-Controlled access (Cisco PIX-525 firewall) at the entrance of the network; • Partially isolated local traffic (6 divisions have their subnetworks with Cisco Catalyst 3550 as a gateway).

  13. LHC Computing Grid Project (LCG) • LCG Deployment and Operation • LCG Testsuit • Castor • LCG AA- Genser&MCDB • ARDA

  14. Main results of the LCG project • Development of the G2G (GoToGrid) system to maintain installation and debug the LCG site. • Participation in the development of the CASTOR system: elaboration of a subservient module that will be served as a garbage collector. • Development of structure of the database, creation of a set of base modules, development of a WEB-interface for creation/addition of articles to the database (description of files with events and related objects) http://mcdb.cern.ch • Testing a reliability of data transfer on the GidFTP protocol implemented in the Globus Toolkit 3.0 package. • Testing the EGEE middleware components (GLite): Metadata and Fireman catalogs. • Development of a code of constant WMS (Workload Management System) monitoring the INFN site gundam.chaf.infn.it in the testbed of a new EGEE middleware Glite.

  15. LCG AA- Genser&MCDB • Correct Monte Carlo simulation of complicated processes requires rather sophisticated expertise • Different physics groups often need same MC samples • Public availability of the event files speeds up their validation • Central and public location where well-documented event files can be found The goal of MCDB is to improve the communication between Monte Carlo experts and end-users

  16. Main Features of LCG MCDB The most important reason to develop LCG MCDB is to expel the restrictions of the CMS MCDB • An SQL-based database • Wide search abilities • Possibility to keep the events at particle level as well as at partonic level • Large event files support – storage: Castor in CERN • Direct programming interface from LCG collaboration software • Inheritance of all the advantages of the predecessor - CMS MCDB

  17. MCDB Web Interface http://mcdb.cern.ch Only Mozilla Browser Supported (for the time being)

  18. High Energy Physics WEB at LIT Idea:Create a server with WEB access to computing resources of LIT for Monte Carlo simulations, mathematical support and etc. • Provide physicists with informational and mathematical support; • Monte Carlo simulations at the server; • Provide physicists with new calculation/simulation tools; • Create copy of GENSER of the LHC Computing GRID project • Introduce young physicists into HEP world. Goals: HIJING Web Interface HepWeb.jinr.ru will include FRITIOF, HIJING, Glauber approximation, Reggeon approximation, …

  19. Fixed Bug in the HIJING Monte Carlo Model secures energy conservation V.V. Uzhinsky (LIT)

  20. G2G is a web-based tool to support the generic installation and configuration of (LCG) grid middleware • The server runs at CERN • Relevant site-dependent configuration information is stored in a database • It provides added-value tools, configuration files and documentation to install a site manually (or by a third-party fabric management tool)

  21. G2G features are thought to be useful for ALL sites … • First level assistance and hints (Grid Assistant) • Site profile editing tool • … for small sites … • Customized tools to make manual installation easier • … for large sites … • Documentation to configure fabric management tools • … and for us (support sites) • Centralized repository to query for site configuration
