Enum GpuTier 

pub enum GpuTier {
    Tier1,
    Tier2,
    Tier3,
    Tier4,
}

GPU compute tier classification (from algorithm analysis).

Higher tiers benefit more from GPU acceleration.

Variants

Tier1

Massive speedup: O(N⁴) two-electron integrals, O(grid × N_basis) orbital grids.

Tier2

Significant speedup: O(N²) matrix builds (overlap, Fock, Coulomb), O(voxels) marching cubes.

Tier3

Moderate speedup: O(N²) pairwise (D4 dispersion, EEQ Coulomb, KPM Chebyshev).

Tier4

CPU-preferred: SCF loop control, DIIS, eigensolve (latency-bound).

Implementations

impl GpuTier

pub fn gpu_recommended(&self) -> bool

Whether GPU dispatch is recommended for this tier.

Trait Implementations

impl Clone for GpuTier

fn clone(&self) -> GpuTier

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GpuTier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for GpuTier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for GpuTier

fn eq(&self, other: &GpuTier) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
