Fields

dnnl_dims_t strides

The strides between the outermost blocks.

In case of plain (non-blocked) formats the strides between dimensions.

int inner_nblks

The number of innermost blocks, e.g. 3 in case of OIhw_4i16o4i_

dnnl_dims_t inner_blks

The size of the blocks, e.g. {4, 16, 4} in case of OIhw_4i16o4i

dnnl_dims_t inner_idxs

The logical indices of the blocks, e.g.

{1, 0, 1} in case of 4i16o4i, because i is the 1st dim and o is the 0st dim
