Sparks: Coherence as an Abstract Type
نویسنده
چکیده
Sparks is a protocol construction framework that treats records of coherence actions as abstract types. Sparks’ central abstraction is the coherence history, an object that summarizes past coherence actions to shared segments. Histories provide high-level access to coherence guarantees. We motivate our work by discussing synchronization design in distributed shared memory systems, and show how histories can be used to cleanly create more efficient synchronization than is currently used.
