Ticket #213 (new defect)
Optimized collective updates
|Reported by:||hauma||Owned by:||boh|
A collective update on a replicated object that does not employ PartialReplication corresponds to an all-to-all operation in MPI, because each replica must communicate its changes to each other replica. But if a replicated object is partially replicated, changes to one replica are only relevant for a small subset of all replicas. This fact should be used to optimize collective updates for partially replicated objects.
