而message passing则只需要维护一个状态机,每个状态只需要记住当前的role;而且即使是全局模型,也很容易拆分成相对独立的模块。 我的感觉是,程序员里面,哪怕是自称对memory system很了解(以至于可以扮演教师开讲堂)的人,哪怕是看了几本经典教科书之后大喊醍醐灌顶的人,也还处在自以为了解的状态。最最简单的,什么时候...
Shared memory versus message passing Tasks can use two different methods to communicate with each other. The first one is shared memory, and normally it is used when the tasks are running in the same computer. The tasks use the same memory area where they write and read values. To avoid p...
1.1 Emulating shared memory with message passing Two communication models have mainly been considered in distributed com- puting: (1) the message passing model and (2) the shared memory model. In the first model, we typically assume that the processes are connected through ...

An 800MHz 320mW 16-core processor with message-passing and shared-memory inter-core communication mechanisms Almost all multicore processors use a shared-memory architecture due to its simple programming model. Recently, however, the message-passing mechanism is a... Z Yu,K You,R Xiao,... -...

Current and emerging high-performance parallel com puter architectures generally implement one of two types of communication mechanisms: shared memory (SM) or message passing (MP). In this paper we propose a hybrid SM/MP architecture together with a hybrid SM/MP programming model, that we believe...
This paper describes the methods used and experiences made with implementing a finite element application on three different parallel computers with either message passing or shared virtual memory as the programming model. Designing a parallel finite element application using message-passing requires to fin...
Microsoft ® Message Passing Interface (MPI), calledMS MPI, is a portable, flexible, vendor- and platform-independent interface for messaging on HPC nodes. MPI is the specification, and MS MPI, MPICH2, and others are the implementations of that standard. MPI2 is an extension of the origina...
It is presented a comparative performance study of a coarse grained parallel neural network training code, implemented in both OpenMP and MPI, standards for shared memory and message passing parallel programming environments, respectively. In addition, these versions of the parallel training code are co...
