Struct MulticastObject 

pub struct MulticastObject { /* private fields */ }

A multicast object. Drop releases the underlying CUmemGenericAllocationHandle via cuMemRelease.

Implementations

impl MulticastObject

pub fn new(num_devices: u32, size_bytes: usize) -> Result<Self>

pub fn add_device(&self, device: &Device) -> Result<()>

pub fn bind_mem( &self, mc_offset: usize, mem_handle: CUmemGenericAllocationHandle, mem_offset: usize, size: usize, ) -> Result<()>

Bind a VMM allocation handle at mc_offset → (mem_handle, mem_offset, size).

pub fn bind_addr( &self, mc_offset: usize, ptr: CUdeviceptr, size: usize, ) -> Result<()>

Bind an already-mapped device pointer into the multicast object.

pub fn unbind( &self, device: &Device, mc_offset: usize, size: usize, ) -> Result<()>

pub fn as_raw(&self) -> CUmemGenericAllocationHandle
