Properties of the device related to the accelerator hardware.

Plane size min/max

This is a range of possible values for the plane size.

For Nvidia GPUs and HIP, this is a single fixed value.

For wgpu with AMD GPUs this is a range of possible values, but the actual configured value is undefined and can only be queried at runtime. Should usually be 32, but not guaranteed.

For Intel GPUs, this is variable based on the number of registers used in the kernel. No way to query this at compile time is currently available. As a result, the minimum value should usually be assumed.

Fields

plane_size_min: u32

The minimum size of a plane on this device

plane_size_max: u32

The maximum size of a plane on this device

max_bindings: u32

minimum number of bindings for a kernel that can be used at once.

max_shared_memory_size: usize

Maximum amount of shared memory, in bytes

max_cube_count: CubeCount

Maximum CubeCount in x, y and z dimensions

max_units_per_cube: u32

Maximum number of total units in a cube

max_cube_dim: CubeDim

Maximum CubeDim in x, y, and z dimensions

num_streaming_multiprocessors: Option<u32>

Number of streaming multiprocessors (SM), if available

num_tensor_cores: Option<u32>

Number of tensor cores per SM, if any

min_tensor_cores_dim: Option<u32>

The minimum tiling dimension for a single axis in tensor cores.

For a backend that only supports 16x16x16, the value would be 16. For a backend that also supports 32x8x16, the value would be 8.
