EGEE tutorial introduction Luciano Gaido INFN -Torino INFN-GRID/EGEE Grid User Tutorial Torino, January 18-19, 2005 EGEE tutorial introduction Luciano Gaido INFN -Torino www.eu-egee.org EGEE is a project funded by the European Union under contract IST-2003-508833

Goals of the tutorial give an introduction on the current EGEE middleware give an overview of the grid services and infrastructure show how to use the grid resources INFN-GRID/EGEE Grid User Tutorial - Torino, 18-19.01.05 - 2

Some preliminary info DataGrid (EDG): grid project funded by the EU FP5 (2001-2004) middleware release (base for LCG) LCG (LHC Computing Grid): http://www.cern.ch/LCG “CERN” project started in 2002 european grid infrastructure (partially overlapping with INFNGRID infrastructure) middleware release (e.g. LCG2) INFNGRID: http://grid.infn.it INFN project started in 2000 italian grid production infrastructure (aka Grid.it) middleware release (e.g. INFNGRID-2.3.0, based on LCG-2.3.0) INFN-GRID/EGEE Grid User Tutorial - Torino, 18-19.01.05 - 3

Few notes on EGEE The EGEE middleware system has been developed in several different languages and by many different people in different countries Programming languages such as C, C++, Python, Java etc. have been used End user APIs usually exist in either C, C++ or Java CLI and API libraries are either available in /opt/edg or /opt/lcg …/bin CLI commands .../lib for C, C++ libraries .../share/java for Java libraries The API signature is not very coherent; primarily due to different languages, technologies and maturity of middleware parts Web services usually allow for a higher diversity of language bindings (APIs) than standard C or C++ based services INFN-GRID/EGEE Grid User Tutorial - Torino, 18-19.01.05 - 10
