📄️ Checkpoint and Restart
In SST 14, SST has begun to bring back support for checkpoint/restart. Under the checkpoint/restart infrastructure, a particular SST simulation can be checkpointed only if all of the elements it uses support checkpointing (that is, are serializable). Thus, it will be necessary for developers to add checkpointing capability to their models. The current infrastructure is experimental and has several temporary limitations described below. It was released to enable developers to start adding checkpoint support in anticipation of a fully-functional checkpoint/restart capability. We also expect that as element libraries are made checkpointable and we discover new requirements, the SST-Core support may need modifications.
