Checkpointing Síncrono Bloqueante Minimal com Iniciadores Concorrentes

Tiemi C. SakataIslene C. GarciaLuiz E. Buzato

Synchronous checkpointing protocols coordinate the collection of checkpoints to easy the recovery of the system in case of failure. A blocking protocol suspends the underlying computation during checkpoint collection and a minimal protocol forces only a minimal number of process to take checkpoints. In this paper, we present a new minimal blocking checkpointing protocol that requires fewer control messages than the protocols proposed in the literature. We first analyze a simpler version of this protocol that assumes the existence of only one initiator at a time. After that we present an extension that handles concurrent initiators.
