Struct allocator_suite::memory_sources::mmap::numa::numa_node_bit_set::NumaNodeBitSet

pub struct NumaNodeBitSet {
    pub static_nodes: bool,
    pub relative_nodes: bool,
    // some fields omitted
}

NUMA nodes to allocate on.

If set to no nodes (the Default::default()) then memory is allocated on the local node if possible.

Ignored on operating systems other than Android and Linux.

Fields

static_nodes: bool

Specifies physical node IDs.

Linux does not remap the nodemask when the thread moves to a different cpuset context, nor when the set of nodes allowed by the thread's current cpuset context changes.

(Not used if there are no nodes specified).

relative_nodes: bool

Specifies specifies node IDs that are relative to the set of node IDs allowed by the thread's current cpuset.

(Not used if there are no nodes specified).
