Struct Strategy2x4 

pub struct Strategy2x4;

An inner loop implementation strategy using 2 parallel instances of the schema accumulator with a manual inner loop unroll of 4.

Trait Implementations

impl MainLoop for Strategy2x4

unsafe fn main<S, L, R, A>( loader: &Loader<S, L, R, A>, trip_count: usize, epilogues: usize, ) -> S::Accumulator

where A: Architecture, S: SIMDSchema<L, R, A>,

The implementation here has a global unroll of 4, but the unroll factor of the main loop is actually 8.

There is a single peeled iteration at the end that handles the last group of 4 if needed.

const BLOCK_SIZE: usize = 4

The effective number of unrolling (in terms of SIMD vectors) performed by this kernel. For example, if BLOCK_SIZE = 4 and the SIMD width is 8, than each iteration of the main loop will process 4 * 8 = 32 elements.
