一般来说,CL的性能要优于CF,因为可以省掉activation的reorder,这也是当初去优化channels last的最大动因。 另外,PyTorch上面的默认格式是CF的,对于特定OP来说,如果没有显示的CL支持,NHWC的input会被当作non-contiguous的NCHW来处理,从而output也是NCHW的,这带来的一个问题就是整个memory format传递的链条会被打断。也...

如果算子中包含一连串的数学运算,那么只需要2次dtype转换:首先,input从bf16转到fp32;然后进行多个数学运算;最后,output从fp32转回bf16。比如Sigmoid得计算: /* * Example-3: sigmoid * * sigmoid will compute -, exp, +, /. * the code will also compile 2. with Vectorized<BFloat16> * but it will...
