Struct DeviceMeshPlan 

pub struct DeviceMeshPlan<B: AcceleratorBackend> {
    pub topology: DeviceTopology<B>,
    pub index_of: HashMap<PointId, u32>,
}

A device topology plus the host-only stable-ID lookup needed to compile operation-specific plans.

Fields

topology: DeviceTopology<B>

Device CSR arrays.

index_of: HashMap<PointId, u32>

Stable point ID to dense device index. This map is never uploaded.

Implementations

impl<B: AcceleratorBackend> DeviceMeshPlan<B>

pub fn compile<T: PayloadLike>( backend: &B, frozen: &FrozenSieveCsr<PointId, T>, topology_version: u64, ) -> Result<Self, AcceleratorError>

Compile an immutable CSR topology into device arrays.

pub fn validate_topology(&self, current: u64) -> Result<(), AcceleratorError>

Ensure this plan still corresponds to the current topology version.
