Struct numa_gpu::runtime::cpu_affinity::CpuAffinity

pub struct CpuAffinity { /* private fields */ }

Implementations

impl CpuAffinity

pub fn from_slice(affinity_list: &[u16]) -> Self

Takes a slice containing CPU core affinities.

pub fn from_file(path: &Path) -> Result<Self>

Reads a list of CPU core affinities from a file.

CPU core affinities should be listed in a single line and separated with spaces. E.g.:

0 2 4 6 1 3 5 7

Lines that start with ‘#’ are ignored as comments.

pub fn thread_to_cpu(&self, tid: u16) -> Option<u16>

Maps a thread ID to a CPU core ID.

Returns a CPU core ID, or None if the thread ID is out-of-bounds. Core IDs are guaranteed to be in the order given on construction.

pub fn set_affinity(&self, tid: u16) -> Result<()>

Binds the current thread to the CPU core by the given thread ID.

Core IDs are guaranteed to be in the order given on construction.

pub fn len(&self) -> usize

Returns the number of CPU core IDs currently stored in the mapping.

pub fn get_cpu() -> Result<u16>

Returns the CPU core ID that the calling thread is currently running on.
