This crate provides a consistent way to set core affinity for currently running threads and processes.
use affinity::*;
fn bind_even_cores() {
// Select every second core
let cores: Vec<usize> = (0..get_core_num()).step_by(2).collect();
println!("Binding thread to cores : {:?}", &cores);
// Output : "Binding thread to cores : [0, 2, 4, 6]"
set_thread_affinity(&cores).unwrap();
println!("Current thread affinity : {:?}", get_thread_affinity().unwrap());
// Output : "Current thread affinity : [0, 2, 4, 6]"
}Complete example here.
- Bind to multiple cores
- Return list of currently bound cores
- Reliably get number of cores (uses num_cpus)
- Allow caller to handle errors
- Supports affinity inheritance for new child processes on Windows (through
set_process_affinity())
Currently only tested on :
- Windows
- Linux (Arch x64)
