triton-ascend-reduce

适用于归约(reduce)类算子和含归约子步骤的复合算子(如归一化)的优化指南。典型算子包括:sum, mean, max, min, prod, argmax, argmin, cumsum, cumprod, softmax, logsoftmax, layernorm, rmsnorm, groupnorm, instancenorm, batchnorm, l1norm, l2norm, frobeniusnorm, var, std, average_pooling, sum_pooling 等。特别重要:当归约维度不是最后一维(如 dim=1 归约 shape=[B,F,D1,D2]),需要正确处理多维索引和两阶段归约。包含 PyTorch normalized_shape 多轴归一化语义说明。不适用于纯逐元素运算或矩阵乘法。如果算子是损失函数(先逐元素计算再全局归约),应选择 elementwise-reduce-fused 指南。
