基于多核集群系统的并行编程模型的研究

并行计算技术是计算机技术发展的重要方向之一。当前并行程序模型主要有消息传递模型和共享存储模型两种。随着处理器多核技术的发展，在一枚多核处理器中集成两个或多个完整的计算引擎（内核），并充分利用多核计算机的特性，发挥多核计算机的性能成为一个很重要的研究方向。介绍一种新的MPI实现机制，这种机制集成了共享存储模型和消息通信模型的优点，在节点内使用共享存储模型，在节点间使用消息传递模型，并且通过自动生成线程级的任务来获得更好的性能。．

Research of Parallel Programming Model Based on Multi-Core Cluster System

Parallel computing is one of the most important techniques of computing.Contemporary parallel programming model can be roughly divided into message-passing model and shared-memory model.With the development of multi-core processor,this integrated two or more intact computing engine(kernel) in one processor.There arouses a very important researching direction as how to effectively utilize the feature of the multi-core to achieve optimal performance.Introduce a new implementation of MPI,which could integrates the features of both the shared-memory model and the message-passing model,that is,use shared-memory model within one node while use message-passing model among nodes.And more over,better performance is achieved through automatic thread-level task spawning mechanism.
