功能说明

  • API功能：Compressor是推理场景下SAS和QLI的前处理算子，用于将每4或128个token的KV cache压缩成一个，然后每个token与这些压缩的KV cache进行DSA计算。在长序列的情况下，Compressor可以有效地减少计算开销。

  • 计算公式：

    压缩阶段：

    1. 计算矩阵乘法：
      • C4A: \left[kv\_state^a, score\_state^a\right] = X @ \left[W^{aKV}, W^{aGate}\right], \left[kv\_state^b, score\_state^b\right] = X @ \left[W^{bKV}, W^{bGate}\right];
      • C128A: \left[kv\_state, score\_state\right] = X @ \left[W^{KV}, W^{Gate}\right]
    2. 计算分组加法：
      • C4A: score\_state_i^\prime = \left[score\_state_{\left[4(i-1)+1:4i,:\right]}^a; score\_state_{\left[4i+1:4(i+1),:\right]}^b\right] + Ape,~i=1,2,\cdots, \frac{s}{4};
      • C128A: score\_state_i^\prime = score\_state_{\left[128(i-1)+1:128i,:\right]} + Ape,~i=1,2,\cdots, \frac{s}{128};
    3. 计算分组Softmax：
      • C4A: S_i^\prime = softmax(score\_state_i^\prime),~i=1,2,\cdots, \frac{s}{4};
      • C128A: S_i^\prime = softmax(score\_state_i^\prime),~i=1,2,\cdots, \frac{s}{128};
    4. 计算Hadamard乘积：
      • C4A: (S_H)_i = S_i^\prime \odot \left[kv\_state^a_{\left[4(i-1)+1:4i,:\right]} ; kv\_state^b_{\left[4i+1:4(i+1),:\right]}\right],~i=1,2,\cdots, \frac{s}{4};
      • C128A: S_H = S_i^\prime \odot kv\_state;
    5. 沿着压缩轴分组求和：
      • C4A: C_{i}^{\text{Comp}} = \left[1\right]_{1\times8} @ (S_H)_i, ~i=1,2,\cdots, \frac{s}{4};
      • C128A: C_{i}^{\text{Comp}} = \left[1\right]_{1\times128} @ (S_H)_i, ~i=1,2,\cdots, \frac{s}{128};

    后处理阶段：

    1. 计算RMSNorm：
      • \text{RMS}(C^{\text{Comp}}) = \sqrt{\frac{1}{N} \sum_{i=j* N}^{(j+1)* N} {(C_{i}^{\text{Comp}})}^{\text{2}} + norm\_eps} ,N=head\_dim, ~j=1,2,\cdots, \frac{s}{cmp\_ratio}
      • \text{RmsNorm}(C^{\text{Comp}}) = norm\_weight \cdot \frac{C_{i}^{\text{Comp}}}{\text{RMS}(C^{\text{Comp}})}
    2. 计算Rope；

  • 主要计算过程为：

    1. 将输入$X$与$W^{KV}$做Matmul运算得到$kv_state$，将输入$X$与$W^{Gate}$做Matmul运算后再与$Ape$做Add运算得到$score_state$，$kv_state$与$score_state$根据输入的start_pos及cu_seqlens完成更新。
    2. 在coff为2的情况下对$kv_state$和$score_state$进行数据重排。
    3. 对$score_state$进行softmax运算将softmax结果与$kv_state$做Mul计算，后进行ReduceSum运算。
    4. 根据输入数据norm_weight、rope_sin、rope_cos，进行RMSNorm和Rope运算，得到$cmp_kv$结果输出。

  • 输入shape限制：
    • wkv支持输入shape[coff* D,H]
    • wgate支持输入shape[coff* D,H]
    • kv_state、score_state支持输入shape[block_num,block_size,coff* D]，要求block_num>0。
    • ape支持输入shape[cmp_ratio,coff* D]
    • norm_weight支持输入shape[D,]
    • start_pos支持输入shape[B,]
    • 若x的维度采用BS合轴，即x的输入shape为[T,H]
      • rope_sin、rope_cos要求输入shape为[min(T,T//cmp_ratio+B),rope_head_dim]。
      • cu_seqlens输入shape必须为[B+1,]。该参数中每个元素的值表示当前batch与之前所有batch的token数总和，即前缀和，因此后一个元素的值必须大于等于前一个元素的值，且第一位必须位0。

    • 若x的维度不采用BS合轴，即x的输入shape为[B,S,H]
      • rope_sin、rope_cos要求输入shape为[B,ceil(S/cmp_ratio),rope_head_dim]。
      • cu_seqlens，参数必须为空。
      • seqused，支持输入shape[B,]，要求每个Batch的有效token数要求小于等于对应Sequence Length长度，即要求seqused[n] <= S，且不小于0。
      • kv_block_table、score_block_table支持输入shape[B,ceil(Smax/block_size)]。Smax为每个Batch中最大的Sequence Length，即Smax=max(start_pos)+S。
      • cmp_kv，输出shape为[B,ceil(S/cmp_ratio),D]：(compressed_tokens+pad0) + (compressed_tokens+pad1) + ... + (compressed_tokens+padN)。

      • norm_x，输出shape为[B,ceil(S/cmp_ratio),D]。
      • norm_rstd，输出shape为[B,ceil(S/cmp_ratio)]。
  • 输入值域限制：
    • 该接口支持B、S泛化，且存在如下场景限制：
      • 部分长序列场景下，如果计算量过大可能会导致出现超过NPU内存的报错，注：这里计算量会受x输入shape的影响，值越大计算量越大。典型的长序列（即B、S的乘积或T较大）场景包括但不限于：
      B S H
      100 65525 4096
      25 261120 4096
      100 131072 4096
      100 261120 4096
  • 输入属性限制：
    • 支持D为128/512。
    • 支持H为1K~10K，512对齐。
    • 泛化支持block_size小于等于1024，16对齐。
    • 支持cmp_ratio为4/128。支持如下三种情况：
      • C4A: D=512, coff=2, cmp_ratio=4；
      • C4Li: D=128, coff=2, cmp_ratio=4；
      • C128A: D=512, coff=1, cmp_ratio=128。
    • 支持rotary_mode为2，Rope计算模式为interleave。
