Fine-Grain Distributed Shared Memory on Clusters of Workstations
Shared memory, one of the most popular models for programming parallel platforms, is becoming ubiquitous both in low-end workstations and high-end servers. With the advent of low-latency networking hardware, clusters of workstations strive to offer the same processing power as high-end servers for a fraction of the cost. In such environments, shared memory has been limited to page-based systems...

متن کاملFine-Grain Software Distributed Shared Memory on SMP Clusters
Commercial SMP nodes are an attractive building block for software distributed shared memory systems. The advantages of using SMP nodes include fast communication among processors within the same SMP node and potential gains from clustering where remote data fetched by one processor is used by other processors on the same node. The widespread availability of SMP servers with small numbers of pr...
متن کاملHPF on Fine-Grain Distributed Shared Memory: Early Experience
This paper examines the performance of a suite of HPF applications on a network of workstations using two different compilation approaches: generating explicit message-passing code, and generating code for a shared address space provided by a fine-grain distributed shared memory system (DSM). Preliminary experiments indicate that the DSM approach performs with usually a small slowdown compared ...
متن کاملEfficient support for fine-grain parallelism on shared-memory machines
A coarse-grain parallel program typically has one thread (task) per processor, whereas a fine-grain program has one thread for each independent unit of work. Although there are several advantages to fine-grain parallelism, conventional wisdom is that coarse-grain parallelism is more efficient. This paper illustrates the advantages of fine-grain parallelism and presents an efficient implementati...
