This book provides a hands-on, class-tested introduction to CUDA and GPU programming. It begins by introducing CPU programming and the concepts of P-threads, thread programming, multi-tasking, and parallelism, and then interweaves those concepts into an introduction of GPU programming. Using ...
This __global__ function is known as a CUDA kernel, and runs on the GPU. Code that runs on the GPU is often called device code, while code that runs on the CPU is host code.Memory Allocation in CUDATo compute on the GPU, I need to allocate memory accessible by the GPU. Unified ...
CUDA Architecture 是NVIDIA创造的一种允许 GPU 既能完成传统图形学任务又能完成那些 general-purpose 任务的架构,与之对应的编程语言即为 CUDA C(也可以简称为 CUDA),CUDA 即为 C 加上一些关于并行编程的拓展。 Chapter 1: Why CUDA? Why Now? 算是序章,主要讲了 GPU、并行计算和 CUDA 的历史。略过。 Chap...
因此书中建议只在 CPU-GPU 之间存在拷贝时使用这类 memory,即作为 cudaMemcpy的起点或者终点时。 然后我们来看代码,主要是测试两种内存的速度对比,up和down意思是 host-to-device 或者 device-to-host。 这是我的测试结果,可以看出性能差距还是比较大的。

鉴于自己的毕设需要使用GPU CUDA这项技术,想找一本入门的教材,选择了Jason Sanders等所著的书《CUDA By Example an Introduction to General Purpose GPU Programming》。这本书作为入门教材,写的很不错。自己觉得从理解与记忆的角度的出发,书中很多内容都可以被省略掉,于是就有了这篇博文。此博文记录与总结此书的...
have long been available for demanding graphics and game applications. CUDA now brings this valuable resource to programmers working on applications in other domains, including science, engineering, and finance. No knowledge of graphics programming is required–just the ability to program in a modestly...
