An Efficient Hybrid Cache Coherence Protocol for Shared Memory Multiprocessors

{ This paper presents a new tree-based cache coherence protocol which is a hybrid of the limited directory and the linked list schemes. By utilizing a limited number of pointers in the directory, the proposed protocol connects the nodes caching a shared block in a tree fashion. In addition to the low communication overhead, the proposed scheme also contains the advantages of the existing bit-ma...

Adaptive Cache Coherency for Detecting Migratory Shared

Parallel programs exhibit a small number of distinct data-sharing patterns. A common data-sharing pattern, migratory access, is characterized by exclusive read and write access by one processor at a time to a shared datum. We describe a family of adaptive cache coherency protocols that dynamically identify migratory shared data in order to reduce the cost of moving them. The protocols use a sta...

Coherency in Distributed Shared Memory

We present a new model for distributed shared memory systems, based on remote data accesses. Such features are offered by network interface cards that allow one-sided operations, remote direct memory access and OS bypass. This model leads to new interpretations of distributed algorithms allowing us to propose an innovative detection technique of race conditions only based on logical clocks. Ind...

Eager Combining: a Coherency Protocol for Increasing Eeective Network and Memory Bandwidth in Shared-memory Multiprocessors

One common cause of poor performance in large-scale shared-memory multiprocessors is limited memory or interconnection network bandwidth. Even well-designed machines can exhibit band-width limitations when a program issues an excessive number of remote memory accesses or when remote accesses are distributed non-uniformly. While techniques for improving locality of reference are often successful...

Eager combining: a coherency protocol for increasing effective network and memory bandwidth in shared-memory multiprocessors

An excessive number of remote accesses or a non-uniform distribution of remote accesses can cause even well-designed multiprocessors to exhibit severe memory and network contention. Producer/consumer data generates a particularly common sharing pattern that results in a non-uniform distribution of references. In this paper we quantify the performance impact of producer/consumer sharing as a fun...
