Struct CostEstimate 

pub struct CostEstimate {
    pub flops: u64,
    pub bytes_moved: u64,
    pub kernel_overhead_ns: u32,
}

Coarse cost model for one kernel invocation. Layer-1 of the architecture’s cost-model tower (FLOP counts + bandwidth + launch overhead). Layer-2 — empirical refinement from per-deployment telemetry — composes on top of these without changing this shape.

Fields

flops: u64

Compute pressure — number of floating-point operations.

bytes_moved: u64

Bandwidth pressure — bytes moved through device memory hierarchy for this kernel’s inputs + outputs (excluding cache hits).

kernel_overhead_ns: u32

Fixed launch overhead. CPU kernels measure this in tens of ns; GPU launches in low microseconds.
