Abstract
A technique includes generating a checkpoint for an application that is executing on a plurality of nodes of a distributed computing system. Forming the checkpoint includes selectively regulating communication of data from the plurality of nodes to a storage subsystem based at least in part on a replication of the data among the nodes.
Claims20
A method comprising:
- generating a checkpoint for an application, the application being executed in a distributed fashion across a plurality of nodes of a distributed computing system,
- wherein forming the checkpoint comprises selectively regulating communication of data from the plurality of nodes to a storage subsystem based at least in part on a replication of the data among the nodes.
A method comprising:
- generating an incremental checkpoint for an application executing on a least one computing node,
- wherein the generating comprises identifying at least one memory region of the at least one computing node which has changed after generation of a prior checkpoint based at least in part on a prediction on whether the at least one memory region is expected to change after the generation of the prior checkpoint.
A system comprising:
- a distributed computing system comprising a plurality of nodes;
- and
- a storage subsystem separate from the distributed computing system to form a checkpoint for an application executing on the nodes, the storage subsystem being adapted to selectively regulate communication of data from the plurality of nodes to the storage subsystem based at least in part on a replication of the data among the nodes.
