0x2. 教程1 Vector Addition阅读 在这里插入图片描述 意思是这一节教程会介绍Triton编程模型定义kernel的基本写法,此外也会介绍一下怎么实现一个良好的benchmark测试。下面来看计算kernel实现,我把注释改成中文了: import torch import triton import triton.language as tl @triton.jit def add_kernel(x_ptr, # *...
* Vector addition: C = A + B. * * This sample is a very basic sample that implements element by element * vector addition. It is the same as the sample illustrating Chapter 2 * of the programming guide with some additions like error checking. */ #include <stdio.h> // For the CUD...
本篇文章开始入门一下OpenAI的Triton,然后首先是从Triton介绍博客看起,然后对triton官方实现的vector_add和fused_softmax还有Matmul教程做一个阅读,也就是 https://triton-lang.org/main/getting-started/tutorials/ 这里的前三节,熟悉一下triton编写cuda kernel的语法。 OpenAI Triton官方教程:https://triton-lang.org...
Here, each of the N threads that execute VecAdd() performs one pair-wise addition【两两相加】. 2.2. Thread Hierarchy【线程层次结构】 For convenience, threadIdx is a 3-component vector【三分量向量】, so that threads can be identified using a one-dimensional, two-dimensional, or three-di...

What follows is a simple vector addition script (the complete code is at the end of this page). As we are concentrating primarily on the code, I'll show you how to carry this out using NVIDIA's Nsight environment (Eclipse edition). I believe this is a very useful resource for those ...
printf("Vector addition on GPU \n"); for (int i = 0; i < N; i++) { if (h_a[i] + h_b[i] != h_c[i]) { correct = 0; break; } } if (correct == 1) { printf("GPU has computed Sum Correctly!\n"); } else ...
__device__ __half2 __hadd2_sat (const __half2 a, const __half2 b) Performs half2 vector addition in round-to-nearest-even mode, with saturation to [0.0, 1.0]. Parameters a - half2. Is only being read. b - half2. Is only being read. www.nvidia.com CUDA Math API vRelease...
Full code for the vector addition example used in this chapter and the next can be found in the vec- torAdd CUDA sample. 5.1. Kernels CUDA C++ extends C++ by allowing the programmer to define C++ functions, called kernels, that, when called, are executed N times in parallel by N ...
