Hi,
Has anybody successfully used an external sorting mechanism? What characteristics should such a mechanism have in order for spss to be able to use it? When would an external algorithm offer advantages? (a quicksort for nearly-sorted data?)
SORT Subcommand
By default, IBM® SPSS® Statistics tries to use an external, third-party sorting mechanism, which
may reduce processing time with large data sources. The third-party sorting option is available
only if you have SPSS Statistics Server. The specific sorting engine is defined by your server
administrator. If you are not connected to the SPSS Statistics Server or the SPSS Statistics Server
cannot find the third-party sort engine, the built-in sorting mechanism is used.
EXTERNAL Use the external, third-party sort engine if available. This setting is the default. If
the third-party sort engine is not available, this setting is ignored, and the built-in
sorting mechanism is used. COXREG and CURVEFIT use built-in sorting regardless
of the SORT setting.
INTERNAL Use the built-in sorting mechanism.
SS This setting is deprecated. It has the same effect as
EXTERNAL.
Regards,
Albert-Jan
