课程还类比线粒体在细胞中的作用，将multi_tensor_apply比喻为优化器的“动力卡车”，强调了其同时处理多个张量的能力，与传统的逐个张量处理方式形成对比。课程探讨了在CUDA中实现多个张量操作（如_foreach_add）时，如何正确传递输入，以及如何避免非法内存访问的问题。通过对不同方法的尝试和分析，课程...

第二张和第三张Slides尝试使用std::vector<float*>来实现_foreach_add_kernel,这种方法不行,因为CUDA不识别std::vector。 第四张和第五张Slides尝试使用C风格的数组(float**)来实现_foreach_add_kernel,结论:这种方法也不行,会导致非法内存访问(IMA),因为外层指针*是CPU地址。 Slides里面还画了一些示意图用于...
