LCG Monte-Carlo Events Data Base (MCDB) : current status and plans


Overview
Overview

  • Motivations

    • To Provide Configuration, Book-keeping, Documentation, Storage for the Shared Monte-Carlo Event Files

    • To keep track of the full generation chain, Exploiting the Competences of Monte Carlo Experts and Monte Carlo Authors

  • CMS MCDB [hep-ph/0403100]http://cmsdoc.cern.ch/cms/generators/mcdb/

    • Only parton level files; AFS storage; No Searchable; No SQL

  • LCG MCDB[hep-ph/0404241] http://mcdb.cern.ch

    • Same authors + Additional human resources and technical support

    • Core software supported by LCG Software Project Infrastructure

      • MySQL; POOL; CASTOR (RFIO); CGI; Perl; Apache

1


The mcdb project structure
The MCDB Project Structure

  • Authors management and Authorisation block

  • Articles Management

  • Event Files management

  • Log system

  • Documentation

  • Users comments management

  • Search engine

  • Application Package Interface

  • Uniform Event Formats and Event Interfaces

2


Existent mcdb subsystems
Existent MCDB subsystems

  • Users area:

  • Web site

  • Web catalog (physics categories)

  • Search engine

  • Downloading event files

  • Comments on articles

  • Authors area:

  • Articles Management

  • Event files management

  • Administrative area:

  • Authors management

  • Authorisation system

  • Physical categories/web catalog management

  • Articles management

  • Other subsystems:

  • Logging system

3







Articles management 95 done
Articles Management (95% done)

  • Provide authors clear interface to document events as easy as possible

  • It is possible to use pre-entered information to describe generator, model, parameters, etc.

  • Present articles in a very structured way

9



Articles management generator and process description
Articles Management, generator and Process description

Event files management 90 done
Event Files Management (90% done)

  • Uploading to disk (as in CMS MCDB) : for files cashing - accomplished

  • Interface to CASTOR - in progress ( will be done in two weeks )

  • GRID and API interfaces (in the future)

14


Authors management system done
Authors Management System (done)

  • Web interface to add, remove, block and edit author records and policies

  • Simple registration procedure

15


Authorisation system 95 done
Authorisation System(95% done)

  • Based on CERN AFS authorisation system

  • Direct connection with MySQL authors

    management system

  • Grid-ecrtificate based authorization: in the future

16



Logging and statistics system 20 done
Logging and statistics system(20% done)

  • Login operations

  • Implicit logs in database (e.g. creation or modification date)

  • Separate log files for different subsystems

  • Need to combine to uniform structure

  • Add structure to search engine

18


Porting to scientific linux cern 3
Porting to Scientific Linux CERN 3

  • Installation of all nessesary software and packages

  • Detailed instructions how to setup MCDB from the very beginning

  • Ready-to-use MCDB version on pcitapi26.cern.ch under SLC3

19


Conclusion working prototype is ready
Conclusion :working prototype is ready

  • We have a working version of MCDB

    - Basic functionality is supported

    - Deployed on http://pcitapi26.cern.ch

  • But still need to do a few important things in the nearest future:

    - Adjusting operations with Castor ( in two weeks )

    - Porting MCDB to mcdb.cern.ch under SLC3

    - Making Web-interface more convinient to end-users

    - Checking for resistance against any kind of faults

    - API to collaborations software

    - Cleanup of MCDB tree in CVS and installation scripts
