Expand description

GPU-resident PIR graph (device-side mirror of pir::PirGraph).

Fields§

§node_type: TrackedCudaSlice<u8>§child_offsets: TrackedCudaSlice<u32>§children: TrackedCudaSlice<u32>§leaf_id: TrackedCudaSlice<u32>§decision_var: TrackedCudaSlice<u32>§decision_child_false: TrackedCudaSlice<u32>§decision_child_true: TrackedCudaSlice<u32>

Implementations§

Source§

impl GpuPirGraph

Source

pub fn from_host( pir: &PirGraph, provider: &Arc<CudaKernelProvider>, ) -> Result<Self>

Upload a host PIR graph to device buffers.

This is intended for tests and tooling. Production GPU-native paths should construct PIR directly on device.

Source

pub fn num_nodes(&self) -> usize
