This paper is a brief introduction to a new class of computers, the reconfigurable massively parallel computer. Its most distinguishing feature is the utilization of the reconfigurability of the interconnection network to establish a network topology well mapped to the algorithm communication graph so that higher efficiency can be achieved, and to remove faulty processors from the network so that the system operation can be kept uninterrupted while maintaining the same or slightly degraded efficiency. Several existing reconfigurable single instruction multiple data (SIMD) parallel architectures and their reconfiguration mechanism are described, the effectiveness of algorithm mapping, through reconfiguration, is demonstrated, and fault-tolerant schemes via reconfiguration are discussed
