Shared-memory multiprocessor systems use private (or per processor) caches to enhance system performance by reducing average memory access time. In-cache modification of shared data in such systems leads to a data inconsistency problem referred to as the cache coherence problem. A solution to the ...
Integrating cache coherence protocols for heterogeneous multiprocessor systems. 1 This systematic methodology maintains cache coherency in a heterogeneous shared-memory multiprocessor system on a chip. It works with any combination of pr... T Suh,HHS Lee,DM Blough - 《Micro IEEE》 被引量: 27发表:...
即使在多核处理器中,也可以套用这些Cache coherence protocol,只不过global bus的另一侧从内存变成了shared Last Level Cache。下面来看看它的implementation: 1. on write through cache HI P319 考虑一个简单的write through、no write-allocate的cache,对cacheline的任何改写操作都会立即被写回内存。假设系统中有两...

Synchronization: 虽然coherence(通过使cache透明)和consistency(通过使shared memory看起来像一个"single module")保证shared memory程序的正确性,但还需要适当的同步机制(锁、屏障等,见shared memory synchronization一书)。 Cormmercial relaxed models Consistency in distributed systems: 本书仅讨论shared memory系统中的...
This paper is a review of the recent research about the design of cache coherence protocols in shared-memory multiprocessors. Two important aspects of shared memory systems are memory consistency and cache coherence. Two major available protocols for cache coherence problems are snoopy coherence and di...
Implementing low-latency cache coherence in these systems is difficult, because traditional approaches either add indirection for common cache-to-cache misses (directory protocols) or require a totally-ordered interconnect (traditional snooping protocols). Unfortunately, totally-ordered interconnects are diffic...
Cache coherence in shared-memory multiprocessor systems has been studied mostly from an architecture viewpoint, often by means of aggregating metrics. In many cases, aggregate events provide insufficient information for programmers to understand and optimize the coherence behavior of their applications. A...
