Evaluation of 18-stage pipeline hardware sorter

Parallel database systems

“…The basic unit, called a processing module (PM), consists of one or more processors on a shared memory. These processors are augmented by a special purpose sorting engine that sorts at high speed (3MB/s at present), and by a disk subsystem [KITS89]. Clusters of processing modules are connected via an omega network that provides both non-blocking NxN interconnect and some dynamic routing minimize skewed data distribution during hash joins.…”
