Cuda is a technology that can make supercomputers personal. The soul of supercomputer is the body of gpu, a gpu is a specially designed processor that helps 3D or 2D graphics from restoring from the microprocessor. Cuda Architecture includes a unified shader pipeline, allowing each and every ...

1.2 CUDA:一个通用计算平台和模型 2006年nvidia发布了cuda,它可以在nvidia的gpu上进行设计和计算,应该说也算是opencl的一种实现吧,但是现在cuda的库还是要比opencl多多了,不过网上有大佬表示科学计算还是opencl用的多?不是很清楚,现在还没接触到gpu集群的服务器╮(╯▽╰)╭ ...

CUDA编程模型假定系统由主机和设备组成,主机和设备都有自己独立的内存。核函数运行在设备内存中。CUDA编程模型暴露了来自GPU体系结构的内存层次结构的抽象,下图展示了一个简化的GPU内存结构,包括两个主要组成部分:全局内存和共享内存。 来源:Preofessional CUDA® C Programming 下表列出了内存操作的标准C函数及其对应的...
故 CUDA 程序可以被执行在具有任意 kernel 数据的 GPU 中,如下图所示,同时在运行时阶段,系统只需要给出物理多处理器地个数。 1.细粒度数据并行性与线程并行性 细粒度并行性意味着每个单独的任务(比如一个线程)处理的是更小的数据块。CUDA通过将问题划分为多个线程来实现这种并行性,每个线程都独立工作。线程彼此...
