Detailed Description

Memory resource that uses cudaMallocFromPoolAsync/cudaFreeFromPoolAsync with a managed memory pool for allocation/deallocation.

Constructor & Destructor Documentation

◆ cuda_async_managed_memory_resource()

rmm::mr::cuda_async_managed_memory_resource::cuda_async_managed_memory_resource ( )

Constructs a cuda_async_managed_memory_resource with the default managed memory pool for the current device.

The default managed memory pool is the pool that is created when the device is created. Pool properties such as the release threshold are not modified.

Exceptions

rmm::logic_error if the CUDA version does not support cudaMallocFromPoolAsync with managed memory pool

Member Function Documentation

◆ operator=() [1/2]

cuda_async_managed_memory_resource& rmm::mr::cuda_async_managed_memory_resource::operator= ( cuda_async_managed_memory_resource && )

default

Default move assignment operator.

Returns: cuda_async_managed_memory_resource& Reference to the assigned object

◆ operator=() [2/2]

cuda_async_managed_memory_resource& rmm::mr::cuda_async_managed_memory_resource::operator= ( cuda_async_managed_memory_resource const & )

default

Default copy assignment operator.

Returns: cuda_async_managed_memory_resource& Reference to the assigned object

◆ pool_handle()

cudaMemPool_t rmm::mr::cuda_async_managed_memory_resource::pool_handle ( ) const

noexcept

Returns the underlying native handle to the CUDA pool.

Returns: cudaMemPool_t Handle to the underlying CUDA pool
