NODE PROCESSOR FOR A PARALLEL OBJECT-ORIENTED TOTAL ARCHITECTURE A-NET

A node processor for a highly parallel computer based on a parallel ob ject-oriented computational model has been developed. The node process or consists of a PE for the execution of methods and a router for the control of message communication. The prototype PE has a high-level in struction set that includes message sending and receiving instructions . It also supports both tagged data structure as a synchronization mec hanism and dynamic data typing. The special hardware unit for tag proc essing achieves a speed up of about 44 percent for an add instruction. The router has been designed as independent to network-topology. It t akes approximately 5.2 mu s to transfer a 35-byte message to an adjace nt node. Message transfers over multiple nodes take approximately 1.0 mu s per hop.
