Fine-grain and coarse-grain computing architectures are evaluated with regard to a hardware implementation with optoelectronic interconnects. Three examples for fine-grain optoelectronic VLSI architectures are presented and their hardware requirements are specified. Furthermore technological aspects of a realisation of an optical interface with high density for fine-grain optoelectronic VLSI ar...

Within the parallel genetic algorithm framework, there currently exists a growing dichotomy between coarse-pain and fine-grain parallel architectures. This paper attempts to characterize the need for fine-grain parallelism. and to introduce and compare three models of fine-grain parallel genetic algorithms (GAS). The performance of the three models is examined on seventeen test problems and is ...
