operation

struct operation

The operation interface represents an action an instruction will perform. All operation classes must be CopyConstructible.

bool migraphx::internal::is_context_free(const operation &x)

Returns true if operation does not require a context to run compute.

bool migraphx::internal::has_finalize(const operation &x)

Returns true if the operation has a finalize method.

struct binary : public migraphx::internal::op::op_name<Derived>

#include <migraphx/op/binary.hpp>

struct broadcast

#include <migraphx/op/broadcast.hpp>

The broadcast operator performs the numpy-style broadcasting of an axis of a given tensor. This is achieved primarily by setting the stride of the broadcasted axis to zero. Linear indicies are computed from multi-indicies by computing the inner product on the multi-index with the strides. For example, if we have a tensor A(2,3) it has lengths of (2,3) and strides of (3,1). If we want to compute the linear offset that corresponds to the element on the 2nd row (i = 1) and 3rd column (j = 2), we compute the following inner product (1,2) dot (3, 1) = 1*3 + 2*1 = 5. It is obvious from there that we can negate the effects of a given axis by setting the stride of that axis to zero.

struct capture

#include <migraphx/op/capture.hpp>

struct ceil : public migraphx::internal::op::unary<ceil>

#include <migraphx/op/ceil.hpp>

struct clip

#include <migraphx/op/clip.hpp>

struct concat

#include <migraphx/op/concat.hpp>

struct contiguous

#include <migraphx/op/contiguous.hpp>

The contiguous operator takes a non-standard input tensor and returns the same tensor but in standard form. For example, if input tensor A which has lens = (4,5) is first transposed, i.e. lens = (5,4), this tensor’s data layout remained the same during the transpose operation; only it’s shape lengths and strides were changed. This leaves the tensor in a non-standard form. The contiguous operator copies the underlying data such that resulting tensor is returned to a standard form.
