burn_cubecl::kernel::reduce

Enum SumStrategy 

Source 
pub enum SumStrategy {
    OneShot(u32),
    Chained(KernelReduceStrategy),
    Autotune,
}
Expand description

Select a strategy to perform a sum.

Variants§

§

OneShot(u32)

Run a single kernel with many cubes working in parallel to sum all elements. The provided value is the number of elements summed per unit (up-to-rounding )

§

Chained(KernelReduceStrategy)

Use multiple kernels

§

Autotune

Available on crate feature autotune only.

Use autotune to find the best cube count given the hardware and the input.
