Abstract
A massively parallel data processing system is disclosed. This data processing system includes a plurality of nodes, with each node having at least one processor, a memory for storing data, a processor bus that couples the processor to the memory, and a remote memory access controller coupled to the processor bus. The remote memory access controller detects and queues processor requests for remote memory, processes and packages the processor requests into request packets, forwards the request packets to the network through a router that corresponds to that node, receives and queues request packets received from the network, recovers the memory request from the request packet, manipulates local memory in accordance with the request, generates an appropriate response packet acceptable to the network and forwards the response packet to the requesting node.
