A fault tolerant model for a functional language parallel machine

The paper describes a fault tolerant model for a functional language parallel machine. The model is transparent to the user and ensures successful execution of programs in the presence of hardware failure. The model is based on data replication. It takes advantage of the properties of the functional languages. The recovery scheme can be carried out simultaneously on all processors and occurs while "normal" program execution is in progress. Thus normal execution suffers less performance degradation than with other approaches.<
