%X Fault tolerance can be achieved by means of redundancy.
Multicomputer architectures allow duplicated tasks to run on
multiple processors. In this paper we focus on multicomputer
systems consisting of a small number of processors (4 to
16). Fault tolerance instrumented in the operating system
level tolerates hardware faults. This type of fault
tolerance is known as software implemented fault tolerance.
The information exchange of the computers requires a
powerful communication system with fault tolerance
properties. Since no standard system meets all requirements
a new design was necessary. This paper describes concept,
hardware, firmware and performance of the transputer based
broadcast communication system (BCS).
