Abstract

We describe a parallel checkpoint/restart mechanism. The checkpoint is performed among the participating parallel tasks using a new algorithm that we call stop and discard. Tasks may be checkpointed without waiting for previously sent messages to be received. Specific message logging is not required. Message data that may be in transit is saved in the checkpoint files.
