TVM Operator Inventory (TOPI)简介

TOPI简介

这是 TVM Operator Inventory (TOPI) 的介绍。TOPI 提供了比 TVM 具有更高抽象的 numpy 风格的，通用操作和调度。TOPI 如何在 TVM 中，编写样板代码。

from __future__ import absolute_import, print_function

import tvm

import tvm.testing

from tvm import te

from tvm import topi

import numpy as np

基本示例

重新审视行总和操作（相当于B = numpy.sum(A, axis=1)），要计算二维 TVM 张量 A 行总和，应该指定符号操作及调度。

n = te.var("n")

m = te.var("m")

A = te.placeholder((n, m), name="A")

k = te.reduce_axis((0, m), "k")

B = te.compute((n,), lambda i: te.sum(A[i, k], axis=k), name="B")

s = te.create_schedule(B.op)

以人类可读的格式，检查 IR 代码，可以这样做。

print(tvm.lower(s, [A], simple_mode=True))

输出：

primfn(A_1: handle) -> ()

  attr = {"from_legacy_te_schedule": True, "global_symbol": "main", "tir.noalias": True}

  buffers = {A: Buffer(A_2: Pointer(float32), float32, [n: int32, m: int32], [stride: int32, stride_1: int32], type="auto")}

  buffer_map = {A_1: A} {

  allocate(B: Pointer(global float32), float32, [n]), storage_scope = global;

  for (i: int32, 0, n) {

    B[i] = 0f32

    for (k: int32, 0, m) {

      B[i] = ((float32*)B[i] + (float32*)A_2[((i*stride) + (k*stride_1))])

    }

  }

}

对于这样一个常见的操作，必须定义 reduce 轴，以及使用 te.compute进行显式计算 。对于更复杂的操作，需要提供多少细节。可以用简单topi.sum的，如numpy.sum，替换这两行。

C = topi.sum(A, axis=1)

ts = te.create_schedule(C.op)

print(tvm.lower(ts, [A], simple_mode=True))

输出：

primfn(A_1: handle) -> ()

  attr = {"from_legacy_te_schedule": True, "global_symbol": "main", "tir.noalias": True}

  buffers = {A: Buffer(A_2: Pointer(float32), float32, [n: int32, m: int32], [stride: int32, stride_1: int32], type="auto")}

  buffer_map = {A_1: A} {

  allocate(A_red: Pointer(global float32), float32, [n]), storage_scope = global;

  for (ax0: int32, 0, n) {

    A_red[ax0] = 0f32

    for (k1: int32, 0, m) {

      A_red[ax0] = ((float32*)A_red[ax0] + (float32*)A_2[((ax0*stride) + (k1*stride_1))])

    }

  }

}

Numpy 风格的算子重载

可以使用topi.broadcast_add具有正确（可广播特定）shape的张量，添加两个张量。TOPI 为此类常见操作，提供了算子重载。例如，

x, y = 100, 10

a = te.placeholder((x, y, y), name="a")

b = te.placeholder((y, y), name="b")

c = a + b  # same as topi.broadcast_add

d = a * b  # same as topi.broadcast_mul

使用相同的语法重载，TOPI 处理，将原语（int，float）广播到 tensor d - 3.14。

通用调度和融合操作

TOPI 如何免于在较低级别的 API 中，编写显式计算。像以前一样进行调度，TOPI根据给定的上下文，提供更高级别的调度方法。例如，对于 CUDA，可以using only topi.generic.schedule_reduce，调度topi.sum结尾的一系列操作。

e = topi.elemwise_sum([c, d])

f = e / 2.0

g = topi.sum(f)

with tvm.target.cuda():

    sg = topi.cuda.schedule_reduce(g)

    print(tvm.lower(sg, [a, b], simple_mode=True))

输出：

primfn(a_1: handle, b_1: handle) -> ()

  attr = {"from_legacy_te_schedule": True, "global_symbol": "main", "tir.noalias": True}

  buffers = {b: Buffer(b_2: Pointer(float32), float32, [10, 10], []),

             a: Buffer(a_2: Pointer(float32), float32, [100, 10, 10], [])}

  buffer_map = {a_1: a, b_1: b} {

  allocate(T_divide_red: Pointer(global float32), float32, [1]), storage_scope = global;

  attr [IterVar(threadIdx.x: int32, [0:1024], "ThreadIndex", "threadIdx.x")] "thread_extent" = 1024;

  allocate(T_divide_red.rf: Pointer(local float32), float32, [1]), storage_scope = local;

  allocate(reduce_temp0: Pointer(local float32), float32, [1]), storage_scope = local {

    T_divide_red.rf[0] = 0f32

    for (k0.k1.fused.k2.fused.outer: int32, 0, 10) {

      if @tir.likely((((((k0.k1.fused.k2.fused.outer*1024) + threadIdx.x) < 10000) && (((k0.k1.fused.k2.fused.outer*1024) + threadIdx.x) < 10000)) && (((k0.k1.fused.k2.fused.outer*1024) + threadIdx.x) < 10000)), dtype=bool) {

        T_divide_red.rf[0] = ((float32*)T_divide_red.rf[0] + ((((float32*)a_2[((k0.k1.fused.k2.fused.outer*1024) + threadIdx.x)] + (float32*)b_2[floormod(((k0.k1.fused.k2.fused.outer*1024) + threadIdx.x), 100)]) + ((float32*)a_2[((k0.k1.fused.k2.fused.outer*1024) + threadIdx.x)]*(float32*)b_2[floormod(((k0.k1.fused.k2.fused.outer*1024) + threadIdx.x), 100)]))*0.5f32))

      }

    }

    attr [meta[tir.CommReducer][0]] "reduce_scope" = @tir.reinterpret(0u64, dtype=handle);

    @tir.tvm_thread_allreduce(1u32, (float32*)T_divide_red.rf[0], True, reduce_temp0, threadIdx.x, dtype=handle)

    if (threadIdx.x == 0) {

      T_divide_red[0] = (float32*)reduce_temp0[0]

    }

  }

}

计算的预定阶段已经累积，可以通过以下方式检查。

print(sg.stages)

输出：

[stage(a, placeholder(a, 0xd9c0fa00)), stage(b, placeholder(b, 0xe225cf70)), stage(T_add, compute(T_add, body=[(a[ax0, ax1, ax2] + b[ax1, ax2])], axis=[iter_var(ax0, range(min=0, ext=100)), iter_var(ax1, range(min=0, ext=10)), iter_var(ax2, range(min=0, ext=10))], reduce_axis=[], tag=broadcast, attrs={})), stage(T_multiply, compute(T_multiply, body=[(a[ax0, ax1, ax2]*b[ax1, ax2])], axis=[iter_var(ax0, range(min=0, ext=100)), iter_var(ax1, range(min=0, ext=10)), iter_var(ax2, range(min=0, ext=10))], reduce_axis=[], tag=broadcast, attrs={})), stage(T_elemwise_sum, compute(T_elemwise_sum, body=[(T_add[ax0, ax1, ax2] + T_multiply[ax0, ax1, ax2])], axis=[iter_var(ax0, range(min=0, ext=100)), iter_var(ax1, range(min=0, ext=10)), iter_var(ax2, range(min=0, ext=10))], reduce_axis=[], tag=elemwise, attrs={})), stage(T_divide, compute(T_divide, body=[(T_elemwise_sum[ax0, ax1, ax2]/2f)], axis=[iter_var(ax0, range(min=0, ext=100)), iter_var(ax1, range(min=0, ext=10)), iter_var(ax2, range(min=0, ext=10))], reduce_axis=[], tag=elemwise, attrs={})), stage(T_divide_red.rf, compute(T_divide_red.rf, body=[reduce(combiner=comm_reducer(result=[(x + y)], lhs=[x], rhs=[y], identity_element=[0f]), source=[T_divide[floordiv(floordiv((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10), 10), floormod(floordiv((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10), 10), floormod((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10)]], init=[], axis=[iter_var(k0.k1.fused.k2.fused.outer, range(min=0, ext=10))], where=tir.likely((((floordiv(floordiv((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10), 10) < 100) && (floordiv((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10) < 1000)) && ((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)) < 10000))), value_index=0)], axis=[iter_var(k0.k1.fused.k2.fused.inner, range(min=0, ext=1024))], reduce_axis=[iter_var(k0.k1.fused.k2.fused.outer, range(min=0, ext=10))], tag=, attrs={})), stage(T_divide_red, compute(T_divide_red.repl, body=[reduce(combiner=comm_reducer(result=[(x + y)], lhs=[x], rhs=[y], identity_element=[0f]), source=[T_divide_red.rf[k0.k1.fused.k2.fused.inner.v]], init=[], axis=[iter_var(k0.k1.fused.k2.fused.inner.v, range(min=0, ext=1024))], where=(bool)1, value_index=0)], axis=[], reduce_axis=[iter_var(k0.k1.fused.k2.fused.inner.v, range(min=0, ext=1024))], tag=, attrs={}))]

可以通过与numpy结果进行比较，测试正确性，如下所示。

func = tvm.build(sg, [a, b, g], "cuda")

dev = tvm.cuda(0)

a_np = np.random.uniform(size=(x, y, y)).astype(a.dtype)

b_np = np.random.uniform(size=(y, y)).astype(b.dtype)

g_np = np.sum(np.add(a_np + b_np, a_np * b_np) / 2.0)

a_nd = tvm.nd.array(a_np, dev)

b_nd = tvm.nd.array(b_np, dev)

g_nd = tvm.nd.array(np.zeros(g_np.shape, dtype=g_np.dtype), dev)

func(a_nd, b_nd, g_nd)

tvm.testing.assert_allclose(g_nd.numpy(), g_np, rtol=1e-5)

TOPI 提供常用的神经网络操作，如 _softmax_ 优化调度

tarray = te.placeholder((512, 512), name="tarray")

softmax_topi = topi.nn.softmax(tarray)

with tvm.target.Target("cuda"):

    sst = topi.cuda.schedule_softmax(softmax_topi)

    print(tvm.lower(sst, [tarray], simple_mode=True))

输出：

融合卷积

可以融合topi.nn.conv2d和topi.nn.relu在一起。

TOPI 函数都是通用函数。对不同的后端，有不同的实现优化性能。对于每个后端，有必要在计算声明和调度的目标范围内调用。TVM 将选择正确的函数，调用目标信息。

data = te.placeholder((1, 3, 224, 224))

kernel = te.placeholder((10, 3, 5, 5))

with tvm.target.Target("cuda"):

    conv = topi.cuda.conv2d_nchw(data, kernel, 1, 2, 1)

    out = topi.nn.relu(conv)

    sconv = topi.cuda.schedule_conv2d_nchw([out])

print(tvm.lower(sconv, [data, kernel], simple_mode=True))

Out:
