    13= Introduction =  
    24The SMOA Computing (the successor of the OpenDSP project) is an open source service acting as a computing provider exposing on demand access to computing resources and jobs over the HPC Basic Profile compliant Web Services interface. In addition the SMOA Computing offers remote interface for Advance Reservations management. 
     
    3234* Instead of  ARES library a Python module (installed by default with SMOA Computing) is used. Thus to make Advance Reservation  capabilities accessible via SMOA Computing you will need Python interpreter (version 2.4 at least) together with the  python library for XML processing (''lxml'' or ''elementtree'').

    152183* You need to create ODBC Data Source Name. You can do this by editing system-wide, i.e. /etc/odbc.ini, configuration file and adding new section. In this example we assume that the DSN (Database Source Name) will be smoa_comp, real database name is also smoa_comp and appropriate drivers for PostgreSQL database (i.e. the <code>libodbcpsql.so</code> and <code>libodbcpsqlS.so</code> files) are located in /usr/local/lib:
