Struct numa_gpu::runtime::linux_wrapper::MemPolicyModes

pub struct MemPolicyModes { /* private fields */ }

Memory policies

See numaif.h and linux/mempolicy.h for definition.

Implementations

impl MemPolicyModes

pub const DEFAULT: MemPolicyModes

Restores default behavior by removing any previously requested policy.

pub const PREFERRED: MemPolicyModes

Specifies that pages should first try to be allocated on a node in the node mask. If free memory is low on these nodes, the pages will be allocated on another node.

pub const BIND: MemPolicyModes

Specifies a strict policy that restricts memory allocation to the nodes specified in the node mask. Pages will not be allocated from any node not in the node mask.

pub const INTERLEAVE: MemPolicyModes

Specifies that page allocations should be interleaved over the nodes in the node mask. This often leads to higher bandwidth at the cost of higher latency.

pub const LOCAL: MemPolicyModes

Specifies that pages should be allocated locally on the node that triggers the allocation. If free memory is low on the local node, pages will be allocated on another node.

pub const STATIC_NODES: MemPolicyModes

Specifies that the nodes should be interpreted as physical node IDs. Thus, the operating system does not reinterpret the node set when the thread moves to a different cpuset context.

Optional and cannot be combined with RELATIVE_NODES.

pub const RELATIVE_NODES: MemPolicyModes

Speficies that the nodes should be interpreted relative to the thread’s cpuset context.

Optional and cannot be combined with STATIC_NODES.

pub const fn empty() -> MemPolicyModes

Returns an empty set of flags

pub const fn all() -> MemPolicyModes

Returns the set containing all flags.

pub const fn bits(&self) -> c_int

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: c_int) -> Option<MemPolicyModes>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: c_int) -> MemPolicyModes

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: c_int) -> MemPolicyModes

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: MemPolicyModes) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: MemPolicyModes) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: MemPolicyModes)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: MemPolicyModes)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: MemPolicyModes)

Toggles the specified flags in-place.

pub fn set(&mut self, other: MemPolicyModes, value: bool)

Inserts or removes the specified flags depending on the passed value.
