Enhancements To The Scalable Coherent Interface Cache Protocol, Robert J. Safranek
Enhancements To The Scalable Coherent Interface Cache Protocol, Robert J. Safranek
Dissertations and Theses
As the number of NUMA system's cache coherency protocols based on the IEEE Std. 1596-1992, Standard for Scalable Coherent Interface (SCI) Specification increases, it is important to review this complex protocol to determine if the protocol can be enhanced in any way. This research provides two realizable extensions to the standard SCI cache protocol. Both of these extensions lie in the basic confines of the SCI architectures.
The first extension is a simplification to the SCI protocol in the area of prepending to a sharing list. Depending if the cache line is marked "Fresh" or "Gone", the flow of events …
