Abstract

The properties of a fault tolerant computer system based on a hexagonal grid of processing elements (called the FMPA system) is investigated through discrete event simulation. An hypothetical test environment is used to investigate the robustness of the system, and to study the sensitivity of the system to processor and bus speeds, to the assignment of tasks to the processors, and the performance of the system after component failure. The system, at least as tested, is remarkably robust, and even seems to perform better in the face of moderate component failure. A description of the simulation program is included, as are suggestions for further research.
