mhlo.async_start (mhlo::AsyncStartOp)

Operação AsyncStart

Essa operação é exclusiva do compilador XLA, portanto ainda não possui uma especificação.

De forma simplificada, essa operação inicia um cálculo assíncrono.

Isso é usado quando existem funções que contêm tanto esperas assíncronas (como DMAs) quanto computação na mesma thread. Por exemplo, uma função pode consistir em uma computação, um DMA, outra computação, um segundo DMA e uma computação final. Isso seria representado por um `async_start` seguido por um `async_update` e um `async_done`. O `async_start` executaria a primeira computação na mesma thread e, em seguida, iniciaria o DMA. O `async_update` aguardaria a conclusão do DMA, caso ainda não tivesse sido concluído, executaria a segunda computação na função e iniciaria o segundo DMA. Finalmente, o `async_done` aguardaria a conclusão deste último DMA e, em seguida, executaria a última computação que precisa ser executada na mesma thread, retornando o resultado dessa computação final.

operands são passados ​​diretamente para a computação. called_computation é a função que será executada de forma assíncrona. execution_thread é o nome da thread na qual ela será executada. A thread principal é chamada de "main". Todas as threads têm nomes.

Isso retorna todo o estado necessário entre operações assíncronas. Após a atribuição do buffer, os valores de retorno representam o espaço necessário para armazenar a entrada, os resultados e quaisquer áreas de rascunho necessárias ou editadas pela operação assíncrona.

mhlo.custom_call (mhlo::CustomCallOp)

CustomCall operation

Sintaxe:

operation ::= `mhlo.custom_call` custom<CustomCallTarget>($call_target_name) `(` $inputs `)`
              attr-dict `:` functional-type(operands, results)

Encapsulates an implementation-defined operation call_target_name that takes inputs and called_computations and produces results .

See: https://github.com/openxla/stablehlo/blob/main/docs/spec.md#custom_call

Exemplo:

%results = "mhlo.custom_call"(%input0) {
  call_target_name = "foo",
  has_side_effect = false,
  backend_config = "bar",
  api_version = 1 : i32,
  called_computations = [@foo]
} : (tensor<f32>) -> tensor<f32>

A custom call invokes code external to XLA. The `inputs` are passed to the
external code, and the external code is expected to produce a result of the
given type. The exact mechanism is backend-specific. For example, in the CPU
backend, a call instruction is emitted which targets a symbol with the name
`call_target_name`.

If XLA runtime is enabled for a backend, then custom calls use the runtime
custom call calling convention to call into the external functions. This
calling convention defines an ABI for encoding arguments, attributes and
results.

Depending on the API version there are two ways to pass extra bits of static
information to the external function:

1. For `API_VERSION_TYPED_FFI` custom calls `backend_config` must be a
   dictionary attribute, that will be encoded according to the custom call
   calling convention and passed to the external function as the attributes
   argument. External code is expected to use declarative bindings (see
   `xla/runtime/custom_call.h`) to decode them at run time. These custom
   calls are only supported if XLA uses XLA runtime.

2. For previous API versions it is the user responsibility to encode extra
   bits of static information as a string `backend_config` attribute, and
   decode it at run time.

mhlo.domain (mhlo::DomainOp)

Domain operation

This operation is private to the XLA compiler, so it is does not yet have a specification.

Informally, these operations are used to group instructions with the same DomainMetadata property. ShardingMetadata is the main use case today to group instructions on the same device. Domain instructions provide two major benefits:

  • Prevent unintentionally optimizing instructions across domains.
  • Automatically assign the metadata of the instructions created in the domain. Without domain instructions, each HLO optimization pass would have to check and propagate the metadata, which would be easy to miss and also adds complexity to the compiler. Since domain instructions connect two different domains, each domain instruction is associated with two DomainMetadata -- one on the operand side and one on the user side of the domain.

mhlo.dynamic_broadcast_in_dim (mhlo::DynamicBroadcastInDimOp)

This operation is functionally identical to broadcast_in_dim op, but the result shape is specified dynamically via output_dimensions .

It also accepts optional attributes to express static knowledge about the expanding behavior of dimensions. If not specified, all dimensions are assumed to be possibly expanding. The sets of dimensions that are known to be expanding and the set of dimensions that are known to be non-expanding must be disjoint and they must be a subset of the operand's dimensions.

mhlo.minimum_broadcast_shapes (mhlo::MinimumBroadcastShapesOp)

Minimizes the rank of two or more shapes to be broadcasted

Sintaxe:

operation ::= `mhlo.minimum_broadcast_shapes` $shapes attr-dict `:` type($shapes) `->` type($results)

Given two or more 1D tensors representing shapes, returns one 1D tensor for each operand, where operand i corresponds to output i .

The returned tensors have the property that they specify a shape which is a reshape of the corresponding input shape, and the broadcasted output shape (using shape::BroadcastOp) of the returned shapes is a reshape of the broadcasted output shape of the input shapes. Among all possibilities with this property, the one is chosen which minimizes the rank of each returned shape.

The general idea of this op is that it can be used for ops which have a broadcasting semantic to operate on shapes with a possibly smaller rank while preserving equivalence of the computed values. After computing the result of the op using reshaped operands, the result can be reshaped to the result that would have been originally computed.

Here is an example with two input shapes:

mhlo.minimum_broadcast_shapes [1, 2, 3, 1, 2, 1],
                                 [1, 1, 1, 2, 3] -> [6, 2, 1], [2, 3]

The broadcasted output shape of the operands is [1, 2, 3, 1, 2, 3], the broadcasted output shape of the outputs is [6, 2, 3]. These two shapes are reshapes of each other, and also each output is a reshape of the corresponding input.

mhlo.ragged_dot (mhlo::RaggedDotOp)

Ragged matrix multiplication over a single ragged dimension

This operation takes three tensor args---lhs, rhs, and group_sizes---and a "ragged_dot_dimension_numbers" attribute. Like dot_general, the lhs and rhs are allowed arbitrary batch and contracting dimensions. Additionally, the lhs is required to have one ragged dimension, and the rhs may have at most one group dimension. The op has three modes, depending on the kind of the lhs ragged dimension.

In mode 1, the shape-signature is [b,m,k], [g,b,k,n], [b,g] -> [b,m,n] . Here the ragged dimension is an lhs non-contracting dimension ( m ). The dimensions b and k represent batch and contracting dimensions respectively. The rhs is required to have a group dimension ( g ).

In mode 2, the shape-signature is [b,m,k], [b,k,n], [b,g] -> [g,b,m,n] . Here the ragged dimension is an lhs/rhs contracting dimension ( k ).

In mode 3, the shape-signature is [b,m,k], [b,k,n], [g] -> [b,m,n] . Here the ragged dimension is an lhs/rhs batch dimension ( b ).

mhlo.xla.rng_get_and_update_state (mhlo::XlaRngGetAndUpdateStateOp)

XlaRngGetAndUpdateState operation

Sintaxe:

operation ::= `mhlo.xla.rng_get_and_update_state` attr-dict

This operation is private to the XLA compiler, so it is does not yet have a specification.

Informally, this operation represents the change of the global random number generator state for rng instructions. The global state is incremented by delta and the old state is returned.

The output is currently defined for a single output type. If this changes in the future to support multiple types, lowering to use of a global memref must ensure that a single memref is still used and updated appropriately.

Atributos

ArgResultAliasAttr

Attribute that models the alias relationship of entry function argument

This attribute captures the alias relationship of an MHLO main function argument to one of the results, denoted by resultIndex . The argTupleIndices and resultTupleIndices are used to index into nested tuples in operand and result respectively. If isMustAlias is true then the operand-result pair must alias.

This is meant to be used as an attribute on a function argument in MHLO. For example, in the following code it expresses that %arg1 may alias 0-th result.

func @main(%arg0: tensor<2xf32>, %arg1: tensor<3xf32> {mhlo.result_alias =
    mhlo.result_alias<result_index = [2], ...>}
  ) -> tensor<2xf32>, tensor<3xf32> {
  // function body ...
}

CrossProgramPrefetchAttr

Argument that is prefetched from another program

Sintaxe:

#mhlo.cross_program_prefetch<
  int64_t,   # parameter
  ::llvm::ArrayRef<int64_t>,   # indices
  std::optional<int64_t>   # offset
>

This attribute captures an argument that is prefetched from another program. For a given CrossProgramPrefetchAttr , parameter tells us which argument of the main function of the module is prefetched, and indices is a shape index telling us what subshape of that argument is prefetched.

A shape has a subshape iff it is a tuple. In that case, the subshape of the tuple by indices is the shape achieved after indexing by each element of indices in turn. For example, the [1,0] subshape of tuple<tuple<token, token>, tuple<tensor<i32>, token>> is tensor<i32> .

An empty value for indices means the whole shape is prefetched.

Por exemplo,

module attributes { mhlo.cross_program_prefetch = [ #mhlo.cross_program_prefetch< parameter = 0, indices = [0]> ]} {
  func.func @copy(%arg0 : tuple<tensor<2x3xi32>, tensor<i32>>) -> tuple<tensor<2x3xi32>, tensor<i32>> {
    %0 = "mhlo.copy"(%arg0) {is_cross_program_prefetch}
    return %0 : tuple<tensor<2x3xi32>, tensor<i32>>
  }
  func.func @main(%arg0 : tuple<tensor<2x3xi32>, tensor<i32>>) -> tuple<tensor<2x3xi32>, tensor<i32>> {
    %1 = "mhlo.async_start"(%arg0) {called_computation=@copy}
    %2 = "mhlo.async_done"(%1) {called_computation=@copy}
    return %2 : tuple<tensor<2x3xi32>, tensor<i32>>
  }
}

The parameter = 0 tells us that the async copy of the 0 th parameter is a cross_program_prefetch , while the index of [0] tells us that the 0 th element of the tuple is prefetched while the other element of the tuple is not.

  ::llvm::ArrayRef<int64_t>,   # outputTupleIndices
  int64_t,   # operandIndex
  ::llvm::ArrayRef<int64_t>   # operandTupleIndices
>

This attribute captures the alias relationship of the output to one of the operands for a CustomCall op, denoted by operand_index . The output_tuple_indices and operand_tuple_indices are used to index into output and operand types. These indices lists are empty if the corresponding types are not tuple types, and can be arbitrarily long in case of arbitrarily nested tuple types.

See https://www.tensorflow.org/xla/aliasing

Example when used as array with in mhlo.custom-call:

%0 = "mhlo.custom_call"(%arg0, %arg1) {
  // other attributes
  output_operand_alias = [
    #mhlo.output_operand_alias<output_tuple_indices = [0],
                               operand_index = 0,
                               operand_tuple_indices = [1]>
  ]
} : (tuple<tensor<1x1xf32>, tensor<2x3xf32>>, tensor<5x5xf32>) -> tuple<tensor<2x3xf32>>

The output and the 0th operand are both tuples. The aliasing shows the
relationship between the 0th element in output tuple with the 1st element in
the 0th operand. And both of them are of the same type: tensor<2x3xf32>.
