Supporting Checkpointing and Process Migration outside the Unix Kernel

  title={Supporting Checkpointing and Process Migration outside the Unix Kernel},
  author={Michael Litzkow Marvin Solomon},
We have implemented both checkpointing and migration of processes under UNIX as a part of the Condor package. Checkpointing, remote execution, and process migration are different, but closely related ideas; the relationship between these ideas is explored. A unique feature of the Condor implementation of these items is that they are accomplished entirely at user level. Costs and benefits of implementing these features without kernel support are presented. Portability issues, and the mechanisms… CONTINUE READING
