Fault-tolerance of a Laboratory Computer Cluster

This paper discusses the research on fault-tolerance of a laboratory computer cluster, which is designed and built by lecturers and students in the courses of Computer Architectures and Fault-tolerant Computer Systems in Burgas Free University. The cluster consists of four single-board computers Raspberry Pi 3, and is used for research on its fault-tolerance in condition of degradation and reconfiguration by simulating failures. Some of the experimental results are presented in the paper.
