Abstract

An overview is presented of the parallel computers developed for the last control system of the ASDEX-Upgrade tokamak. The system consists of six transputer-based computers with fixed or variable processor topology. Up to 29 transputers per computer are used together with a transputer control bus and a fifth-link concept to fully utilize the benefits of parallel processing using only two types of boards as building blocks. The transputer control bus, the fifth links, the variable interconnection network, and the modular and hierarchical structure have proven to be valuable hardware support for the software
