Dubbed STAR, it uses the natural redundancy existing in networks of workstations to offer a high level of fault tolerance.
Fault management is transparent to the supported parallel applications.
STAR is application independent, highly configurable and easily portable to UNIX-like operating systems. The current implementation is based on independent checkpointing and message logging. Measurements show the efficiency and the limits of this implementation. Few related works exist in litterature. Performance evaluation of fault tolerance for parallel applications in networked environments.
