===== Overview =====

Building tools (matching the import and buildcol phases of Greenstone) that make use of the OpenMPI library to provide flexible parallel processing capabilities to Greenstone.

==== Import ====

Currently the import tool is quite basic and essentially splits the collection up into fixed sized batches, processing each with a separate processor.

==== Buildcol ====

Meanwhile the buildcol tool is slightly more complex, as it lets Greenstone Perl code create a XML 'recipe' describing the collection build process and any precedence requirements, and then obeys this recipe farming out parallizable parts of the collection build to separate processes as possible.

===== Requirements =====

Requires the GS2-Extension "tdb-edit" to be installed, compiled and enabled, in order to allow multiple parallel readers/writers to access key datastore/base files (such as the archive-inf databases).
