CUDA comes with a software environment that allows developers to use C as a high-level programming language. As illustrated byFigure 4, other languages, application programming interfaces, or directives-based approaches are supported, such as FORTRAN, DirectCompute, OpenACC. Figure 4. GPU Computing ...
Introduction — CUDA C Programming Guide (nvidia.com) 太长了分了好几个部分,part2,CUDA C++ Programming Guide chapter-three Programming Interface, part2 简介 CUDA C++给熟悉C++编程语言的programmer写运行在设备端的程序,提供了便捷的方式,它包含了C++语言和运行时库的扩展子集。核心的C++语言扩展已经在上一...
CUDA使用扩展的C语言编写内核函数,关键字为global。内核函数返回值只能是void。 下面是一段简单的内核函数,用于求两个数组的和: // Kernel definition__global__voidVecAdd(float*A,float*B,float*C){inti=threadIdx.x;C[i]=A[i]+B[i];}intmain(){...// Kernel invocation with N threadsVecAdd<<<1...
2.4. Heterogeneous Programming【异构编程】 As illustrated byFigure 8, the CUDA programming model assumes that the CUDA threads execute on a physically separate device that operates as a coprocessor to the host running the C program. This is the case, for example, when the kernels execute on ...
1.2 CUDA平台简介 CUDA:NVIDIA GPUs的通用并行计算平台和编程模型,提供了软件环境使得开发者能够使用C语言编程,并且提供了对其他语言和应用的支持。 1.3 可扩展的编程模型 为了解决并行性随着核数增加得到扩展的问题,CUDA并行模型的有三个重要的抽象:线程组、共享内存、同步,对于编程者而言就是语言上的扩展。
以下例子用变量threadIdx来把两个向量A,B进行相加,结果存到C中: // Kernel definition__global__voidVecAdd(float* A,float* B,float* C){inti = threadIdx.x; C[i] = A[i] + B[i]; }intmain(){ ...// Kernel invocation with N threadsVecAdd<<<1, N>>>(A, B, C); ...
