This paper describes a parallel computer architecture for real-time image synthesis. Our architecture is based on a loosely-coupled array of general-purpose processors equipped with a novel frame buffer sub-system called a conflict-free multiport frame buffer (CFMFB) which enables every processor to write any region of the screen without access conflicts. An efficient polygon rendering method using the CFMFB is also described. The method assigns a subset of the polygons to each processor, which independently calculates the images of the assigned polygons with the Z-buffer algorithm. The performance of our system is estimated through simulation experiments with sample scenes.

parallel Proto is a software prototyping tool for analyzing and validating functional requirements which are targeted to either sequential, parallel or distributed architecture environments. Currently, most parallel processing computer-aided software engineering (CASE) tools focus on the identification and simulation of parallelism during the coding stage of the software lifecycle. Such an approach does not take into account any explicit specification of parallelism inherent in the application or an associated parallel-oriented design. Using parallel Proto, parallelism can be explicitly identified and modeled in the requirements and high level design stages of software development. The tool provides facilities for graphically constructing, data-flow-like software functional specifications and parallel and distributed hardware architectures, associating the software functions with the hardware components and interactively executing the functional prototype. Performance modeling statistics are available after prototype execution. Such capabilities support the early analysis of high level software and hardware architecture trade-offs.< >

The WK-recursive networks are highly concurrent message-passing architectures which belong to a class of regular scalable topologies and can be expanded very easily to any size regardless of the node degree. The authors examine the strength and weakness of WK-recursive topologies from a graph point of view and consider the features that make its connectivity appealing. A set of interconnection metrics is defined. A simulation package is developed and a transputer development system (TDS) is used to evaluate the relation between communication time, size of message, and distance traveled.< >

distributed memory, message passing (DMMP) parallel architectures, such as the intel iPSC(R) computer system, provide the processing power and memory to solve very large parallel programming problems. However, their large grain process model and distributed memory complicate the programmer's view of the system. Extensions have been created for interwork II's global object name space in order to support arrays of objects;interwork II distributes the element objects among the processing nodes so as to balance the number on each node. Indexed objects simplify the programmer's view of parallel architectures by enabling related data to be automatically partitioned among the processing nodes. They also speedup computations by allowing these data to be operated on in parallel. This mechanism has proved useful as the basis for constructing a large, parallelsimulation.
