Locks, Directories, and Weak Coherence—a Recipe for Scalable Shared Memory Architectures current bus technology. Lock-based protocols have been suggested as a possible way of mitigating this bottleneck for single bus systems with snooping ability. In this research, we are interested in extending lock-based protocols to general interconnection networks. Directory based cache coherence sFulminate 发表于 2025-3-29 00:32:15
What is Scalability?For this reason, current use of the term adds more to marketing potential than technical insight..In this chapter, I first examine formal definitions of scalability, .. I then question whether scalability is useful and conclude by challenging the technical community to either (1) rigorously define s咆哮 发表于 2025-3-29 07:09:33
Measuring Process Migration Effects Using an MP Simulatormon use for multiprocessors. There is no data sharing between the programs. Each program forms a process that is scheduled to execute on a processor until it blocks because its time-slice expires or for I/O. The process can migrate among the processors when its turn to resume occurs. The degree of p悬崖 发表于 2025-3-29 08:55:47

Scalable Cache Coherence Analysis for Shared Memory Multiprocessorsinked list of caches — forming a . and does not require a global broadcast mechanism. Fully-mapped directory-based solutions proposed earlier also do not require a global broadcast mechanism. However, our solution is more scalable and provides potentially better performance than the fully-mapped dirCougar 发表于 2025-3-29 16:33:04
Reducing Memory and Traffic Requirements for Scalable Directory-Based Cache Coherence Schemes* directory to keep track of all processors caching a memory block. When a write to that block occurs, point-to-point invalidation messages are sent to keep the caches coherent. A straightforward way of recording the identities of processors caching a memory block is to use a bit vector per memory blRespond 发表于 2025-3-29 20:15:56

Delayed Consistencynsistency protocol can be designed from any on-the-fly (non-delayed) protocol. In this paper, we present a write-invalidate delayed protocol..The first gain is in the reduced number of invalidations due to block sharing and a corresponding hit ratio increase. The second gain is in the overlap of cohFUME 发表于 2025-3-30 05:17:10
