Cashmere is a software distributed shared memory (S-DSM) system designed for clusters of server-class machines. It is distinguished from most other S-DSM projects by (1) the effective use of fast user-level messaging, as provided by modern system-are

The different implementations of parallel programming constructs interact heavily with a multiprocessor's coherence protocol and thus may have a significant impact on performance. The form and extent of this interaction have not been established so f

Some of the most common parallel programming idioms include locks, barriers, and reduction operations. The interaction of these programming idioms with the multiprocessor's coherence protocol has a significant impact on performance. In addition, the

In this paper we propose the use of a PCI-based programmable protocol controller for hiding communication and coherence overheads in software DSMs. Our protocol controller provides three different types of overhead tolerance: a) moving basic communic

Shared memory provides an attractive and intuitive programming model for large-scale parallel computing, but requires a coherence mechanism to allow caching for performance while ensuring that processors do not use stale data in their computation. Im

Shared memory is widely regarded as a more intuitive model than message passing for the development of parallel programs. A shared memory model can be provided by hardware, software, or some combination of both. One of the most important problems to
