A system for supporting multi-language versions for software fault tolerance
James M. Purtilo, Pankaj Jalote · 1989
A description is given of a system that allows versions to be coded in different programming languages. The system supports both the recovery block scheme and the N-version programming method. It permits fault tolerance to be used for specified modules that could be embedded in a larger program. The system also allows the different versions to be executed on different machines. It has been implemented in C on DEC Vaxes and Sun 3 workstations and operates in a network of Unix-based machines.>
