Description
|
|
-------------------------------------
|
|
|
|
.. note::
|
|
|
|
The wrapper is under development and its functionality is limited.
|
|
|
|
|
|
CK provides a lightweight wrapper for more complex operations implemented in
|
|
the library. It allows indexing of nested layouts using a simple interface
|
|
(avoiding complex descriptor transformations).
|
|
|
|
Example:
|
|
|
|
.. code-block:: c
|
|
|
|
const auto shape_4x2x4 = ck::make_tuple(4, ck::make_tuple(2, 4));
|
|
const auto strides_s2x1x8 = ck::make_tuple(2, ck::make_tuple(1, 8));
|
|
const auto layout = ck::wrapper::make_layout(shape_4x2x4, strides_s2x1x8);
|
|
|
|
std::cout << "dims:4,(2,4) strides:2,(1,8)" << std::endl;
|
|
for(ck::index_t h = 0; h < ck::wrapper::size<0>(layout); h++)
|
|
{
|
|
for(ck::index_t w = 0; w < ck::wrapper::size<1>(layout); w++)
|
|
{
|
|
std::cout << layout(ck::make_tuple(h, w)) << " ";
|
|
}
|
|
std::cout << std::endl;
|
|
}
|
|
|
|
Output::
|
|
|
|
dims:4,(2,4) strides:2,(1,8)
