功能说明

  • 接口功能:推理网络为了提升性能,将sin和cos输入通过cache传入,执行旋转位置编码计算。该接口相较于aclnnRopeWithSinCosCache接口,新增cacheMode参数,指示拼接cos和sin的方式

    • cacheMode=0时,与aclnnRopeWithSinCosCache实现相同,为分段式拼接cos和sin。
    • cacheMode=1时,为交错式拼接cos和sin。
  • 计算公式:

    1、mrope模式:positions的shape输入是[m, numTokens], m为mropeSection的元素数,支持3或4:

    cosSin[i]=cosSinCache[positions[i]]cosSin[i] = cosSinCache[positions[i]]

    cos,sin=cosSin.chunk(2,dim=−1)cos, sin = cosSin.chunk(2, dim=-1)

    (1)cacheMode为0:

    • mropeSection的元素数为3:

      cos0=cos[0,:,:mropeSection[0]]cos0 = cos[0, :, :mropeSection[0]]

      cos1=cos[1,:,mropeSection[0]:(mropeSection[0]+mropeSection[1])]cos1 = cos[1, :, mropeSection[0]:(mropeSection[0] + mropeSection[1])]

      cos2=cos[2,:,(mropeSection[0]+mropeSection[1]):(mropeSection[0]+mropeSection[1]+mropeSection[2])]cos2 = cos[2, :, (mropeSection[0] + mropeSection[1]):(mropeSection[0] + mropeSection[1] + mropeSection[2])]

      cos=torch.cat((cos0,cos1,cos2),dim=−1)cos = torch.cat((cos0, cos1, cos2), dim=-1)

      sin0=sin[0,:,:mropeSection[0]]sin0 = sin[0, :, :mropeSection[0]]

      sin1=sin[1,:,mropeSection[0]:(mropeSection[0]+mropeSection[1])]sin1 = sin[1, :, mropeSection[0]:(mropeSection[0] + mropeSection[1])]

      sin2=sin[2,:,(mropeSection[0]+mropeSection[1]):(mropeSection[0]+mropeSection[1]+mropeSection[2])]sin2 = sin[2, :, (mropeSection[0] + mropeSection[1]):(mropeSection[0] + mropeSection[1] + mropeSection[2])]

      sin=torch.cat((sin0,sin1,sin2),dim=−1)sin= torch.cat((sin0, sin1, sin2), dim=-1)

      queryRot=query[...,:rotaryDim]queryRot = query[..., :rotaryDim]

      queryPass=query[...,rotaryDim:]queryPass = query[..., rotaryDim:]

    • mropeSection的元素数为4:

      cos=torch.cat([m[i] for i,m in enumerate(cos.split(mropeSection,dim=−1))],dim=−1)cos = torch.cat([m[i]\ for\ i, m\ in\ enumerate(cos.split(mropeSection, dim=-1))], dim=-1)

      sin=torch.cat([m[i] for i,m in enumerate(sin.split(mropeSection,dim=−1))],dim=−1)sin = torch.cat([m[i]\ for\ i, m\ in\ enumerate(sin.split(mropeSection, dim=-1))], dim=-1)

      queryRot=query[...,:rotaryDim]queryRot = query[..., :rotaryDim]

      queryPass=query[...,rotaryDim:]queryPass = query[..., rotaryDim:]

    (2)cacheMode为1:

    cosTmp=coscosTmp = cos

    cos[...,1:mropeSection[1]∗3:3]=cosTmp[1,...,1:mropeSection[1]∗3:3]cos [..., 1:mropeSection[1] * 3:3] = cosTmp[1, ..., 1:mropeSection[1] * 3:3]

    cos[...,2:mropeSection[1]∗3:3]=cosTmp[2,...,2:mropeSection[1]∗3:3]cos[..., 2:mropeSection[1] * 3:3] = cosTmp[2, ..., 2:mropeSection[1] * 3:3]

    sinTmp=sinsinTmp = sin

    sin[...,1:mropeSection[1]∗3:3]=sinTmp[1,...,1:mropeSection[1]∗3:3]sin[..., 1:mropeSection[1] * 3:3] = sinTmp [1, ..., 1:mropeSection[1] * 3:3]

    sin[...,2:mropeSection[1]∗3:3]=sinTmp[2,...,2:mropeSection[1]∗3:3]sin[..., 2:mropeSection[1] * 3:3] = sinTmp [2, ..., 2:mropeSection[1] * 3:3]

    queryRot=query[...,:rotaryDim]queryRot = query[..., :rotaryDim]

    queryPass=query[...,rotaryDim:]queryPass = query[..., rotaryDim:]

    (1)rotate_half(GPT-NeoX style)计算模式:

    x1,x2=torch.chunk(queryRot,2,dim=−1)x1, x2 = torch.chunk(queryRot, 2, dim=-1)

    o1[i]=x1[i]∗cos[i]−x2[i]∗sin[i]o1[i] = x1[i] * cos[i] - x2[i] * sin[i]

    o2[i]=x2[i]∗cos[i]+x1[i]∗sin[i]o2[i] = x2[i] * cos[i] + x1[i] * sin[i]

    queryRot=torch.cat((o1,o2),dim=−1)queryRot = torch.cat((o1, o2), dim=-1)

    query=torch.cat((queryRot,queryPass),dim=−1)query = torch.cat((queryRot, queryPass), dim=-1)

    (2)rotate_interleaved(GPT-J style)计算模式:

    x1=queryRot[...,::2]x1 = queryRot[..., ::2]

    x2=queryRot[...,1::2]x2 = queryRot[..., 1::2]

    o1[i]=x1[i]∗cos[i]−x2[i]∗sin[i]o1[i] = x1[i] * cos[i] - x2[i] * sin[i]

    o2[i]=x2[i]∗cos[i]+x1[i]∗sin[i]o2[i] = x2[i] * cos[i] + x1[i] * sin[i]

    queryRot=torch.stack((o1,o2),dim=−1)queryRot = torch.stack((o1, o2), dim=-1)

    query=torch.cat((queryRot,queryPass),dim=−1)query = torch.cat((queryRot, queryPass), dim=-1)

    2、rope模式:positions的shape输入是[numTokens]:

    cosSin[i]=cosSinCache[positions[i]]cosSin[i] = cosSinCache[positions[i]]

    cos,sin=cosSin.chunk(2,dim=−1)cos, sin = cosSin.chunk(2, dim=-1)

    queryRot=query[...,:rotaryDim]queryRot = query[..., :rotaryDim]

    queryPass=query[...,rotaryDim:]queryPass = query[..., rotaryDim:]

    (1)rotate_half(GPT-NeoX style)计算模式:

    x1,x2=torch.chunk(queryRot,2,dim=−1)x1, x2 = torch.chunk(queryRot, 2, dim=-1)

    o1[i]=x1[i]∗cos[i]−x2[i]∗sin[i]o1[i] = x1[i] * cos[i] - x2[i] * sin[i]

    o2[i]=x2[i]∗cos[i]+x1[i]∗sin[i]o2[i] = x2[i] * cos[i] + x1[i] * sin[i]

    queryRot=torch.cat((o1,o2),dim=−1)queryRot = torch.cat((o1, o2), dim=-1)

    query=torch.cat((queryRot,queryPass),dim=−1)query = torch.cat((queryRot, queryPass), dim=-1)

    (2)rotate_interleaved(GPT-J style)计算模式:

    x1=queryRot[...,::2]x1 = queryRot[..., ::2]

    query=torch.cat((queryRot,queryPass),dim=−1)query = torch.cat((queryRot, queryPass), dim=-1)
