Struct OccupancyEstimate

Source

pub struct OccupancyEstimate {
    pub theoretical_occupancy: f32,
    pub active_warps: u32,
    pub max_warps: u32,
}

Expand description

Occupancy estimate for a single kernel on a given SM configuration.

Fields§

§theoretical_occupancy: f32

Fraction of SM warp slots that would be active (0.0 – 1.0).

§active_warps: u32

Number of warps the kernel uses.

§max_warps: u32

Maximum warps the SM can hold concurrently.

Implementations§

Source §

impl OccupancyEstimate

Source

pub fn compute(kernel: &KernelSpec, sm_warp_limit: u32, warp_size: u32) -> Self

Compute occupancy for kernel on an SM with sm_warp_limit warp slots.

Warp count is derived from threads_per_group / warp_size (rounded up), multiplied by work_groups (capped at sm_warp_limit).

warp_size is typically 32 on NVIDIA hardware; 64 on AMD.
