BatchSizeCalculator

oxirs_vec::gpu::index_builder

Struct BatchSizeCalculator

pub struct BatchSizeCalculator;

Expand description

Calculates optimal batch sizes for GPU index construction based on available GPU memory and vector dimensionality.

Implementations§

impl BatchSizeCalculator

pub fn calculate_batch_size(vector_dim: usize, gpu_memory_mb: u64) -> usize

Calculate optimal batch size given vector dimension and available GPU memory (MB).

Reserves 25% of GPU memory for overhead (distance matrices, working buffers). Returns at least 1.

pub fn optimal_batch_for_float32(dim: usize, memory_mb: u64) -> usize

Optimal batch size assuming f32 vectors, with overhead for distance matrix.

Accounts for the O(batch²) memory of a pairwise distance matrix.
