just-in-time(JIT, 即时编译),即 python 代码运行的时候再去编译cpp和cuda文件。 首先需要加载需要即时编译的文件,然后调用接口函数 from torch.utils.cpp_extension import load cuda_module = load(name="add2", extra_include_paths=["include"], sources=["kernel/add2_ops.cpp", "kernel/add2_kernel....
三类地址空间:Per thread, Per block(shared),Per Program(global) ```cpp #define THREADS_PER_BLOCK 128 // Global Var // N, input, output -> Global Var global void convolve_v2(int N, float input, float output) { int index = blockIdx.x * blockDim.x + threadIdx.x; // Per thread ...
在后来的更复杂的 languages 中,边界变得模糊(例如,在 C++ 和 Java 中,you can create arrays of a size that is decided at runtime),但由于 CUDA 扩展了 C memory model,that is the one we will keep in mind。 The CUDA memory model 在为GPU programming 时,必须记住有两台 machines 可以存储你的 ...

下面是一个简单的CUDA Hello World程序,以及如何获取其SASS代码的步骤: CUDA Hello World cpp // hello.cu __global__ void helloKernel(){ printf("Hello, World from GPU!\n"); } int main(){ helloKernel<<<1,1>>>(); cudaDeviceSynchronize(); return 0; } 生成并查看SASS代码 1. 使用`nvcc`...
5. CS/EE217 GPU Architecture andProgramming GPU架构 在消费级市场上,几乎每一款重要的消费级视频应用程序都已经使用CUDA加速或很快将会利用CUDA来加速,其中不乏Elemental Technologies公司、MotionDSP公司以及LoiLo公司的产品。 在科研界,CUDA一直受到热捧。例如,CUDA现已能够对AMBER进行加速。AMBER是一款 分子动力学模拟...
All CUDA threads in a grid execute the same kernel function; It is easy to explain it. When we want to call a kernel function, we will specify the grid and block structure using thedim3data type. It means that we want to use all these threads where locate in the grid to execute thi...
书写makefile时,使用-fopenmp命令选项时会报nvcc fatal : Unknown option ‘fopenmp’错误。正确的编译选项是: 代码语言:javascript 代码运行次数:0 -Xcompiler-fopenmp 2.nvcc指定GPU计算能力 在内核中调用原子函数(例如atomicAdd)时,如果编译的时候出现”error: identifier “atomicAdd” is undefined”; ...

Hi@Robert_Crovella, sorry for reviving an old thread. I ran into the same issue recently and I just wanted to say thank you for spending the time to explain the whole strategy of debugging an issue. As a beginner in CUDA (and programming in general) your post was very helpful. ...
