簇程──一种大颗粒度的分布并发单元

Cluster-A Kind of Concurrency Mechanism

开发了一个分布式操作系统的原型─—ＣＬＵＳＴＥＲＳ，通过引入两级并发体制，提供了一种称为簇程（ｃｌｕｓｔｅｒ）的大颗粒度并发单元．初步的实践表明，簇程很好地适应了分布式系统对并发机制的独特要求．

Concerned with the coarse grain tasks in a distributed operating systems, this paper described the design and implementation of the prototype of a distributed operating system which named CLUSTERS. CLUSTERS is created based on the Parallel Virtual Machine(PVM). In CLUSTERS, a kind of concurrency mechanism, cluster, is provided to construct coarse grain tasks in distributed applications. It is revealed that cluster can well adapt the requirement to the operating system's concurrency mechanism by kinds of distributed applications.
