For parallelism to become tractable for mass programmers, shared-memory languages and
environments must evolve to enforce disciplined practices that ban" wild shared-memory …

Much of the complexity and overhead (directory, state bits, invalidations) of a typical
directory coherence implementation stems from the effort to make it" invisible" even to the …

BACKGROUND The present invention relates in general to the caching of data in
multiprocessor systems and, more particularly, to simplified cache coherence protocols for …

Cache coherence is ubiquitous in shared memory multiprocessors because it provides a
simple, high performance memory abstraction to programmers. Recent work suggests …

Traditional directory coherence protocols are designed for the strictest consistency model,
sequential consistency (SC). When they are used for chip multiprocessors (CMPs) that …

Recent work has shown that disciplined shared-memory programming models that provide
deterministic-by-default semantics can simplify both parallel software and hardware …

Hierarchical clustered cache designs are becoming an appealing alternative for multicores.
Grou** cores and their caches in clusters reduces network congestion by localizing traffic …

State-of-the-art multiprocessor cache hierarchies propagate the use of a fixed granularity in
the cache organization to the design of the coherence protocol. Unfortunately, the fixed …

Real-time systems are required to respond to their physical environment within predictable
time. While multi-core platforms provide incredible computational power and throughput …

Manycore processors, with tens to hundreds of tiny cores but no hardware-based cache
coherence, can offer tremendous peak throughput on highly parallel programs while being …
