Struct BandwidthBenchmarkConfig 

pub struct BandwidthBenchmarkConfig {
    pub sizes: Vec<usize>,
    pub directions: Vec<TransferDirection>,
    pub warmup_iterations: u32,
    pub benchmark_iterations: u32,
    pub use_pinned_memory: bool,
}

Configuration for a bandwidth benchmark sweep.

Specifies which transfer sizes, directions, and iteration counts to use when running a benchmark. The Default implementation provides a standard set of sizes from 1 KB to 256 MB across all four directions.

Fields

sizes: Vec<usize>

Transfer sizes to benchmark (in bytes).

directions: Vec<TransferDirection>

Transfer directions to benchmark.

warmup_iterations: u32

Number of warmup iterations before timing begins.

benchmark_iterations: u32

Number of timed benchmark iterations per size/direction pair.

use_pinned_memory: bool

Whether to use pinned (page-locked) host memory for transfers.

Implementations

impl BandwidthBenchmarkConfig

pub fn with_sizes(sizes: Vec<usize>) -> Self

Creates a new config with custom sizes and default settings.

pub fn for_direction(direction: TransferDirection) -> Self

Creates a new config for a single direction.

pub fn set_iterations(&mut self, warmup: u32, benchmark: u32)

Sets the number of warmup and benchmark iterations.

pub fn total_transfers(&self) -> usize

Total number of individual transfers this config would produce.

Equal to sizes.len() * directions.len() * benchmark_iterations.
