Roll-Forward Checkpointing Scheme: A Novel Fault-Tolerant Architecture

  title={Roll-Forward Checkpointing Scheme: A Novel Fault-Tolerant Architecture},
  author={Dhiraj K. Pradhan and Nitin H. Vaidya},
  journal={IEEE Trans. Computers},
Proposed here is a novel architecture for a fault-tolerant multiprocessor environment. It is assumed that the multiprocessor organization consists of a pool of active processing modules and either a small number of spare modules or active modules with some spare processing capacity. A fault-tolerance scheme is developed for duplex systems using checkpoints. Our scheme, unlike traditional checkpointing schemes, requires no rollbacks for recovering from single faults. The objective here is to… CONTINUE READING
