Abstract :
(SM)2-II is a large-scale parallel machine dedicated to scientific computation which includes sparse matrix calculations. In order to connect thousands of microprocessors and utilize a high degree of parallelism, the whole (SM)2-II system is designed based on a simple computational model called the node and connecting-line (NC) model. The concept and the architecture of (SM)2-II are described. The NC-model and a language called node oriented concurrent C (NCC) are derived. The concurrent process controller is briefly introduced. Receiver selectable multicast (RSM) is proposed, and the structure which allows connection of a large number of processing units is described. The performance of the RSM is analyzed. Some connection structures for clusters are evaluated. An operational prototype is introduced
