Enum VpAssignment 

pub enum VpAssignment {
    FromTopology,
    Explicit(Vec<u32>),
    Empty,
}

How VPs are assigned to a NUMA node.

Variants

FromTopology

Assign VPs to nodes by round-robining sockets over the CPU-bearing nodes only: a VP with socket ID vp_index / vps_per_socket belongs to the (vp_index / vps_per_socket) % num_cpu_nodes-th FromTopology node. vps_per_socket comes from ProcessorTopologyConfig; num_cpu_nodes is the number of FromTopology nodes, so Empty (CPU-less) nodes are skipped and do not affect the distribution.

Explicit(Vec<u32>)

Explicit VP indices assigned to this node.

Empty

A CPU-less node: no VPs are assigned to it. Unlike Explicit, this may be combined with FromTopology nodes, so a memory- or device-only node can be declared without forcing every other node to spell out its VP set.
