Abstract:
An apparatus and method for a database query optimizer utilizes a combining network to optimize a portion of a query in a parallel computer system with multiple nodes. The efficiency of the parallel computer system is increased by offloading collective operations on node data to the global combining network. The global combining network performs collective operations such as minimum, maximum, sum, and logical functions such as OR and XOR.
