|
* Snapshot Coordination (SNAPC) Interface
|
|
*
|
|
* Terminology:
|
|
* ------------
|
|
* Global Snapshot Coordinator:
|
|
* - HNP(s) coordination function.
|
|
* Local Snapshot Coordinator
|
|
* - VHNP(s) [e.g., orted] coordination function
|
|
* Application Snapshot Coordinator
|
|
* - Application level coordinaton function
|
|
* Local Snapshot
|
|
* - Snapshot generated by a single process in the parallel job
|
|
* Local Snapshot Reference
|
|
* - A generic reference to the physical Local Snapshot
|
|
* Global Snapshot
|
|
* - Snapshot generated for the entire parallel job
|
|
* Global Snapshot Reference
|
|
* - A generic reference to the physical Global Snapshot
|
|
*
|
|
* General Description:
|
|
* ---------------------
|
|
* This framework is tasked with:
|
|
* - Initiating the checkpoint in the system
|
|
* - Physically moving the local snapshot files to a location
|
|
* Initially this location, is the node on which the Head Node Process (HNP)
|
|
* is running, but later this will be a replicated checkpoint server or
|
|
* the like.
|
|
* - Generating a 'global snapshot handle' that the user can use to restart
|
|
* the parallel job.
|
|
*
|
|
* Each component will have 3 teirs of behavior that must behave in concert:
|
|
* - Global Snapshot Coordinator
|
|
* This is the HNPs tasks. Mostly distributing the notification of the
|
|
* checkpoint, and then compiling the physical and virtual nature of the
|
|
* global snapshot handle.
|
|
* - Local Snapshot Coordinator
|
|
* This is the VHNPs (or orted, if available) tasks. This will involve
|
|
* working with the Global Snapshot Coordinator to route the physical
|
|
* and virtual 'local snapshot's from the application to the desired
|
|
* location. This process must also notify the Global Snapshot Coordinator
|
|
* when it's set of processes have completed the checkpoint.
|
|
* - Application Snapshot Coordinator
|
|
* This is the application level coordinator. This is very light, just
|
|
* a subscription to be triggered when it needs to checkpoint, and then,
|
|
* once finished with the checkpoint, notify the Local Snapshot Coordinator
|
|
* that it is complete.
|
|
* If there is no orted (so no bootproxy), then the application assumes the
|
|
* responsibility of the Local Snapshot Coordinator as well.
