Struct OccupancyCalculator 

pub struct OccupancyCalculator { /* private fields */ }

CPU-side occupancy estimator — no GPU calls required.

Given device hardware parameters, this struct computes how many warps can be concurrently resident for a given kernel configuration.

Implementations

impl OccupancyCalculator

pub fn new(device_info: DeviceOccupancyInfo) -> Self

Create a new calculator from device occupancy information.

pub fn device_info(&self) -> &DeviceOccupancyInfo

Return a reference to the underlying device info.

pub fn estimate_occupancy( &self, block_size: u32, registers_per_thread: u32, shared_memory: u32, ) -> OccupancyEstimate

Estimate occupancy for the given kernel configuration.

Parameters

• block_size — threads per block.
• registers_per_thread — registers consumed by each thread.
• shared_memory — shared memory per block in bytes.
