    v129 v130  
    605605QWG templates support profile cloning, a feature known as ''dummy WN'' that allows to speed up dramatically compilation of WNs. This is based on the fact that all WNs generally share the same configuration information, except for the hardware description and some parameters like network configuration.... With profile cloning, instead of compiling separately all WNs (and generally rebuild all of them when one dependency was modified, only one profile, called the ''exact node'' and used as a reference profile, is really compiled. On the other WNs, even though the source profile looks the same, the compilation is not done but instead the reference profile is included in the WN profile and a very small part of the configuration is replayed to do the actual node customization.

     607''Note: disk partitioning and file system configuration are not replayed on each node. This means that the reference profile and the other nodes configured to use cloning must have a similar disk configuration.''

    607609The main variable to enable profile cloning (currently supported only for gLite WN) is `USE_DUMMY`. It is `false` by default and must be set to `true` to enable profile cloning. This variable must be defined to `true` on all WNs, including the reference one (''exact node'').
