描述了CUDA, OpenMPI and OpenMP的基础知识,并进行了比较。对那些不太清楚他们区别的人来说,这篇ppt会有很大的帮助。Describe basics of CUDA, OpenMPI and OpenMP. Good comparision among CUDA, OpenMPI and OpenMP.
Nowadays, NVIDIA’s CUDA is a general purpose scalable parallel programming model for writing highly parallel applications. It provides several key abstractions – a hierarchy of thread blocks, shared memory, and barrier synchronization. This model ha
OpenMP是由The Board of the OpenMP Architecture Review Board(ARB)提出的一套用于共享内存并行系统的多线程程序设计标准。目前,OpenMP仅支持C、C++和Fortran语言。由于OpenMP是一种共享存储的标准,所以在非共享存储系统上不能使用,如集群(Cluster)(目前在非共享存储系统上并行主要采用MPI)。简而言之,OpenMP就是一种多线程程序设计的标准,适合在个人计算机上进行并行计算。它提供了对并行算法的抽象描述,程序员只需在
