ALSO CALLED: Array Processing and Parallel Computing DEFINITION: MPP (massively parallel processing) is the coordinated processing of a program by multiple processors that work on different parts of the program, with each processor using its own operating system and memory. Typically, MPP processors communicate using some messaging

WHITE PAPER:
This white paper details methods for implementing concurrent computing to better meet the performance and scalability needs of increasingly complex business applications on multi-core systems.
WHITE PAPER:
This white paper discusses how two operations in particular -- joins and aggregations -- play an integral role during preprocessing as well in manipulating and consolidating data in a data warehouse.
PARALLEL PROCESSING DEFINITION (continued): … interface. In some implementations, up to 200 or more processors can work on the same application. An "interconnect" arrangement of data paths allows messages to be sent between processors. Typically, the setup for MPP is more complicated, requiring thought about how to partition a common database among processors and how to assign work among the processors. An MPP system is also known as a "loosely coupled" or "shared nothing" system.
