+// Defines the accumulation type for a scalar type.
+// Example:
+//   using accscalar_t = acc_type<scalar_t, /*is_cuda*/true>;
+//
+// Accumulation types are an important concept in numeric computing
+// because you frequently want to perform intermediate computations
+// at a higher precision than the input and output precision, to avoid
+// compounding internal rounding errors.  Accumulation is the most
+// well-known intermediate computation (it is of great importance for
+// sum reduction and matrix multiply, for example), but in PyTorch
+// acc_type ends up getting used for all sorts of other intermediate
+// computations, so it perhaps would be more accurately (ahem) called an
+// "accurate" type.  acc_type is especially important for reduced
+// precision operations like float16 and bfloat16, where relatively
+// benign looking inputs can easily end up overflowing/underflowing.
+//
+// acc_type is parametrized by whether or not you are running on CUDA
+// or not, because on CUDA double precision operations are expensive
+// and so by default, we don't actually want to use double as an
+// acc_type on CUDA.  A lot of things are typed out below, but
+// basically, the table is generated by a few rules:
+//
+//  If bool:
+//      Use 'bool' as acc_type.
+//  If floating point:
+//      If CUDA, use 'float' as acc_type (unless scalar_t is double),
+//      otherwise (CPU) use 'double'
+//  If integral:
+//      Use 'int64_t' as acc_type
+//
+// You're not forced to use this template; if you happen to know
+// something specific about your use case, you can specify your own
+// desired behavior.  This template, however, will give you a reasonable
+// default that will work for all dtypes supported in PyTorch.

+ * The basic strategy for apply is as follows:
+ *
+ * 1. Starting with the outermost index, loop until we reach a dimension where
+ * the data is no longer contiguous, i.e. the stride at that dimension is not
+ * equal to the size of the tensor defined by the outer dimensions. Let's call
+ * this outer (contiguous) tensor A. Note that if the Tensor is contiguous, then
+ * A is equal to the entire Tensor. Let's call the inner tensor B.
+ *
+ * 2. We loop through the indices in B, starting at its outermost dimension. For
+ * example, if B is a 2x2 matrix, then we do:
+ *
+ * B[0][0]
+ * B[0][1]
+ * B[1][0]
+ * B[1][1]
+ *
+ * We set the offset into the underlying storage as (storageOffset + stride_B *
+ * index_B), i.e. basically we compute the offset into the storage as we would
+ * normally for a Tensor. But because we are guaranteed the subsequent data is
+ * contiguous in memory, we can simply loop for sizeof(A) iterations and perform
+ * the operation, without having to follow the order described by the strides of
+ * A.
+ *
+ * 3. As an optimization, we merge dimensions of A that are contiguous in
+ * memory. For example, if A is a 3x3x3x3 tensor narrowed from a 3x3x4x3 tensor,
+ * then the first two dimensions can be merged for the purposes of APPLY,
+ * reducing the number of nested loops.

+// TODO Undo all logic introduced for Note [Avoiding Include Cycles In Static Dispatch]
+// Code introduced to avoid cyclic dependency in static dispatch is no longer
+// needed as static dispatch logic is moved from TensorBody.h, which caused cycles in the first place,
+// to Operators.cpp for supporting multiple backends with multiple kernels.
+//
+// Note [Avoiding Include Cycles In Static Dispatch]
+// In order to avoid #include cycles in the static dispatch build, we've carefully split out
+// the static function definition files into {DispatchKey}Functions.h and {DispatchKey}Functions_inl.h.
+//
+// Without this split, the include cycle looks like TensorBody.h -> CPUFunctions.h -> TensorBody.h.
+// - TensorBody.h #includes CPUFunctions.h in the static dispatch build, because the tensor methods
+//   all need to call into the fastpath C++ API defined in CPUFunctions.h. The methods are also all
+//   directly inlined into TensorBody.h.
+// - CPUFunctions.h #includes TensorBody.h because it contains function declarations for the entire C++ API,
+//   which include functions that have defaultable std::optional<Tensor> arguments.
+//   That requires knowing the full Tensor class definition.
+//
+// We break the cycle by doing the following:
+// - Split out CPUFunction.h into two files: CPUFunctions.h and CPUFunctions_inl.h
+// - CPUFunction.h is a dummy file that just includes the Tensor class and includes CPUFunctions_inl.,
+// - CPUFunctions_inl.h includes everything else
+// - (only in the static dispatch build) TensorBody.h makes sure to finish defining the Tensor class,
+//   and then it includes CPUFunctions_inl.h.
+// - All other files that want the cpu fastpath functions can include CPUFunctions.h directly.
+// - This also means that static dispatch build, CPUFunctions.h only needs to
+//   #include TensorBody.h, and it will automatically bring in CPUFunctions_inl.h.

+// TODO Undo all logic introduced for Note [Avoiding Include Cycles In Static Dispatch]
+// Code introduced to avoid cyclic dependency in static dispatch is no longer
+// needed as static dispatch logic is moved from TensorBody.h, which caused cycles in the first place,
+// to Operators.cpp for supporting multiple backends with multiple kernels.
+//
+// Note [Avoiding Include Cycles In Static Dispatch]
+// In order to avoid #include cycles in the static dispatch build, we've carefully split out
+// the static function definition files into {DispatchKey}Functions.h and {DispatchKey}Functions_inl.h.
+//
+// Without this split, the include cycle looks like TensorBody.h -> CPUFunctions.h -> TensorBody.h.
+// - TensorBody.h #includes CPUFunctions.h in the static dispatch build, because the tensor methods
+//   all need to call into the fastpath C++ API defined in CPUFunctions.h. The methods are also all
+//   directly inlined into TensorBody.h.
+// - CPUFunctions.h #includes TensorBody.h because it contains function declarations for the entire C++ API,
+//   which include functions that have defaultable std::optional<Tensor> arguments.
+//   That requires knowing the full Tensor class definition.
+//
+// We break the cycle by doing the following:
+// - Split out CPUFunction.h into two files: CPUFunctions.h and CPUFunctions_inl.h
+// - CPUFunction.h is a dummy file that just includes the Tensor class and includes CPUFunctions_inl.,
+// - CPUFunctions_inl.h includes everything else
+// - (only in the static dispatch build) TensorBody.h makes sure to finish defining the Tensor class,
+//   and then it includes CPUFunctions_inl.h.
+// - All other files that want the cpu fastpath functions can include CPUFunctions.h directly.
+// - This also means that static dispatch build, CPUFunctions.h only needs to
+//   #include TensorBody.h, and it will automatically bring in CPUFunctions_inl.h.
