GCP is a tool designed to support the execution of pipelines built using GATE Developer over large collections of thousands or millions of documents, using a multi-threaded architecture to make the best use of today's multi-core processors.
GCP tasks or batches are defined using an extensible XML syntax, describing the location and format of the input files, the GATE application to be run, and the kinds of outputs required. A number of standard input and output handlers are provided, but all the various components are pluggable so custom implementations can be used if the task requires it. GCP keeps track of the progress of each batch in a human- and machine-readable XML format, and is designed so that if a running batch is interrupted for any reason it can be re-run with the same settings and GCP will automatically continue from where it left off.
