Expand description

A view of a tensor that starts reading data from a specified offset. Ensures safe access by preventing out-of-bounds errors. Includes pre-fetched shapes and strides for optimized performance.

Implementations§

Source§

impl<EG: Numeric> TensorReader<EG>

Source

pub fn new( tensor: VirtualTensor<EG>, x_offset: u32, y_offset: u32, batch_offset: u32, ) -> Self

Instantiate a read view over the given tensor, pre-fetching needed strides and shapes

Source

pub fn update_view(&mut self, k_offset: u32, ident: InputIdent)

Advance the view along the k dimension by a specified offset, k_offset.

Source

pub fn load_window_in_tile<G: GlobalConfig>( &self, tile: (u32, u32), nth_window: u32, input_ident: InputIdent, config: G, ) -> Window<EG>

Reads data from the tensor view as a window, i.e. a slice of global memory Also returns the length of the slice

The length of the slice is the width of the tile

§Note

If the slice would be partly out-of-bounds, it will simply be shorter. The caller must do the padding if necessary.

Source

pub fn load_window_in_stage<G: GlobalConfig>( &self, nth_window: u32, input_ident: InputIdent, config: G, ) -> Window<EG>

Reads data from the tensor view as a window, i.e. a slice of global memory

The length of the slice is the width of the tile

§Note

If the slice would be partly out-of-bounds, it will simply be shorter. The caller must do the padding if necessary.

Source

pub fn load_coalesced_in_tile<G: GlobalConfig>( &self, tile_x: u32, tile_y: u32, position: u32, input_ident: InputIdent, config: G, ) -> Line<EG>

Reads data from the tensor view at the specified tile coordinates (tile_x, tile_y).

Each unit loads one line in a coalesced manner for improved efficiency. For row-major tensors, subsequent units read lines horizontally within the tile, while for column-major tensors, they read lines vertically.

§Note

Out-of-bounds reads will be translated to zeros.

Source

pub fn load_coalesced_in_stage<G: GlobalConfig>( &self, position: u32, input_ident: InputIdent, config: G, ) -> Line<EG>

Reads data from the tensor view at the specified index within the whole view, without regards to tiles

Each unit loads one line in a coalesced manner for improved efficiency. For row-major tensors, subsequent units read lines horizontally within the tile, while for column-major tensors, they read lines vertically.

§Note

Out-of-bounds reads will be translated to zeros.
