ModelContext

Struct ModelContext 

Source
pub struct ModelContext { /* private fields */ }
Expand description

Explicitly shared allocation, compilation, and scheduling domain for models.

Implementations§

Source§

impl ModelContext

Source

pub fn new(options: RuntimeOptions) -> Result<Self>

Construct a context; hardware and compiler initialization remain lazy.

Source

pub fn runtime(&self) -> &Runtime

Coordinated runtime shared by every model and tensor in this context.

Source

pub fn compiler(&self) -> Result<Compiler>

Lazily obtain the compiler for the selected device’s actual target.

Source

pub fn allocate(&self, desc: TensorDesc) -> Result<DeviceTensor>

Allocate initialized device storage. Empty tensors allocate nothing.

Source

pub fn allocate_with( &self, desc: TensorDesc, placement: MemoryPlacement, ) -> Result<DeviceTensor>

Allocate a tensor with explicit storage placement. Host-visible IO can be submitted and read back directly without transfer staging or copies.

Source

pub fn tensor( &self, desc: TensorDesc, view: BufferView, producer: Completion, ) -> Result<DeviceTensor>

Wrap existing tracked storage without copying. The producer must belong to this runtime or represent already completed initialization.

Source

pub fn upload(&self, desc: TensorDesc, bytes: &[u8]) -> Result<DeviceTensor>

Copy host bytes into owned staging and enqueue upload. The caller may release or mutate its source as soon as this method returns.

Source

pub fn copy_into( &self, destination: &mut DeviceTensor, byte_offset: usize, source: &DeviceTensor, ) -> Result<()>

Copy a contiguous tensor into a byte-aligned subrange of another tensor. Both tensors must be contiguous and have the same dtype. This updates the destination’s producer dependency, preserving failures from earlier writes. Slot owners survive until the copy drains, even if the source is dropped.

Source

pub fn concatenate(&self, inputs: &[DeviceTensor]) -> Result<DeviceTensor>

Concatenate contiguous tensors along their first axis on the device. Inputs must have identical trailing dimensions, dtype and layout. Empty inputs are allowed; scalars and an empty input list are not.

Source

pub fn download(&self, tensor: &DeviceTensor) -> Result<TensorReadback>

Queue readback after a tensor’s producer, without a host wait.

Source

pub fn validate(&self, tensor: &DeviceTensor) -> Result<()>

Reject a tensor from another allocation domain before any work is queued.
