AWhat changed
Designed queue-based local-spinning locks and scalable barriers with bounded remote-reference behaviour.
Scientific scope
The record is the exact two-author 1991 ACM Transactions on Computer Systems paper. It does not absorb Anderson's lock, later queue-lock variants, blocking synchronization or every architecture-specific implementation.
