Cost modelling for hybrid-WSI massively parallel computing modules

Hybrid wafer scale integration (HWSI) is a promising technology for the cost-effective development of the next generation of massively parallel computers (MPCs). It is argued that it is not easy to understand the relative merits and technological tradeoffs associated with vendor-specific factors in order to determine the best technological route for a particular application. Cost models aimed at the resolution of these problems are introduced, and progress towards a design methodology for HWSI devices is reported.
