AGM: a dataflow database machine

GAMMA - A High Performance Dataflow Database Machine

In this paper, we present the design, implementation techniques, and initial performance evaluation of Gamma. Gamma is a new relational database machine that exploits dataflow query processing techniques. Gamma is a fully operational prototype consisting of 20 VAX 11/750 computers. The design of Gamma is based on what we learned from building our earlier multiprocessor database machine prototyp...

Dataflow Parallel Database Systems

Dataflow parallel database systems and LOGFLOW

LOGFLOW is a distributed Prolog system running on multi-transputer machines and workstation clusters. It is based on the dataflow principle. The most recent database management systems prefer shared-nothing architectures and dataflow execution mechanism because of their promising features. In this paper LOGFLOW is examined from the database point of view. Both relational and deductive DBMSs can...

Querying an Integrated Complex-Object Dataflow Database

We consider an integrated complex-object dataflow database in which multiple dataflow specifications can be stored, together with multiple executions of these dataflows, including the complex-object data that are involved, and annotations. We focus on dataflow applications frequently encountered in the scientific community, involving the manipulation of data with a complex-object structure comb...

Control of parallelism in the Manchester Dataflow Machine

Fine-grain parallel ma~:hines, such as tagged-token dataltow machines, allow very high degrees of program parallelism to be exploited for many applications. In fact, so much parallelism can be generated that it is necessary to control parallelism in order to bound store usage. This paper reviews software mechanisms for parallelism control, which rely on merely planting extra code to control exe...
