Detailed Documentation

Memory format tag specification.

oneDNN formats describe physical data layout. The physical layout is described as a sequence of the dimensions as they are laid out in the memory (from the outer-most to the inner-most). Note that this order doesn’t affect the logical order of the dimensions that is kept in the dims field of the dnnl_memory_desc_t structure. The logical order of the dimensions is specified by the primitive that uses the tensor.

For example, CNN 5D tensor always has its logical dimensions in the order (batch, channels, depth, height, width), while the physical layout might be NCDHW (corresponds to dnnl_ncdhw format tag) or NDHWC (corresponds to dnnl_ndhwc format tag).

int batch = 2, channels = 16, depth = 13, height = 13, width = 13;

int ndims = 5; // 5D tensor
dnnl_dims_t dims = {batch, channels, depth, height, width};
dnnl_memory_desc_t data_in_ncdhw;
dnnl_memory_desc_create_with_tag(
     &data_in_ncdhw, 5, dims, dnnl_f32, dnnl_ncdhw);

// note that in both cases dims passed are the same
dnnl_memory_desc_t data_in_ndhwc;
dnnl_memory_desc_create_with_tag(
     &data_in_ndhwc, 5, dims, dnnl_f32, dnnl_ndhwc);

dnnl_memory_desc_destroy(data_in_ncdhw);
dnnl_memory_desc_destroy(data_in_ndhwc);

Memory format tags can be further divided into two categories:

  • Domain-agnostic names, i.e. names the do not depend on the tensor usage in the specific primitive. These names use letters from a to l to denote logical dimension from 1 to 12, and form the order in which the dimensions are laid in memory. For instance, dnnl_ab is used to denote 2D tensor where the second logical dimension (aka b) is the innermost, i.e. has stride = 1, and the first logical dimension (a) laid out in memory with stride equal to the size of second dimension. On the other hand, dnnl_ba is just transposed version of the same tensor: the first dimension (a) becomes the innermost one.

  • Domain-specific names, i.e. names that make sense only in the context of a certain domain, such as CNN. This names are just aliases to the corresponding domain-agnostic tags and used mostly for the convenience. For example, dnnl_nc is used to denote 2D CNN activations tensor memory format, where channels are the innermost dimension and batch is an outermost one. Moreover, dnnl_nc is just an alias to dnnl_ab, since for oneDNN CNN primitives the logical dimensions of activations tensors come in order: batch, channels, spatial. In other words, batch corresponds to the first logical dimension (a), channels correspond to the second one (b).

The following domain-specific notation applies to memory format tags:

  • 'n' denotes the mini-batch dimension

  • 'c' denotes a channels dimension

  • When there are multiple channel dimensions (for example, in convolution weights tensor), 'i' and 'o' denote dimensions of input and output channels

  • 'd', 'h', and 'w' denote spatial depth, height, and width respectively

Upper-case letters indicate that the data is laid out in blocks for a particular dimension. In such cases, the format name contains both upper- and lower-case letters for that dimension with a lower-case letter preceded by the block size. For example: dnnl_nChw8c describes a format where the outermost dimension is mini-batch, followed by the channel block number, followed by the spatial height and width, and finally followed by 8-element channel blocks.
