一、Vector Addition OJ入门均是a+b,GPU 中就是向量C=向量A + 向量B,以下是为我们提供的示例代码。 #include "solve.h" #include <cuda_runtime.h> __global__ void vector_add(const float* A, const float* B, float* C, int N) { } // A, B, C are device pointers (i.e. pointers to...
NVIDIA C++ Standard Library (libcu++) 1.5.0 was released with CUDA 11.4. Thrust 1.12.0 has the new thrust::universal_vector API that enables you to use the CUDA unified memory with Thrust. Nsight developer tools New versions are now available for NVIDIA Nsight Developer Tools: Nsight System ...
Vector Addition (CUDA) In this tutorial, we will look at a simple vector addition program, which is often used as the "Hello, World!" of GPU computing. We will assume an understanding of basic CUDA concepts, such as kernel functions and thread blocks. If you are not already familiar with...

使用传统API进行计算是个不可挽回的错误,CUDA的出现将改变这一状况。CUDA主要在驱动程序方面和函数库方面进行了扩充。在CUDA库中提供了标准的FFT与BLAS库,一个为NVDIA GPU设计的C编译器。CUDA的特色如下,引自NVIDIA的官方说明: 1、为并行计算设计的统一硬件软件架构。有可能在G80系列上得到发挥。
As we all know, the style of many CUDA APIs is C-style, we need to learn about how to use it conjunction with C++. How does the std::vector standard template library use the Device(GPU) memory ? Many examples use the original pointer to point a Device memory. But if we want to ...
