Abstract
A number of partitions of a cellular multiprocessor (CMP) are connected to respective databases and form respective nodes of a data warehouse. Heterogeneous data stored across the nodes is accessed automatically in parallel at high speed from a user site using a simple script request containing a data source object name wherein the heterogeneous data is treated as a single data source object, the script further containing at least one method to be performed on the data source object. Respective agent processes are stored in memory dedicated to each partition and automatically generate descriptor files containing metadata corresponding to the data source object from a repository available to each partition. A messenger process transmits the new scripts to the appropriate nodes via memory-based messaging using a shared portion of the CMP memory. Respective agent processes at each node respond to automatically access the appropriate data and execute specified methods upon it.
