Performance issues in dataflow machines [PDF]

Future Generation Computer Systems, 1987
Abstract Issues affecting the performance of dataflow computers at the machine and language levels are explored. It is suggested that performance is dictated by the nature and the means of identification, distribution and control of workload in the hardware system. Dataflow is an asynchronous concurrent notation based on fine-grain message-passing in
