Detailed Description

device_memory_resource derived class 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 ( )

inline

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

pool_handle()

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

inlinenoexcept

Returns the underlying native handle to the CUDA pool.

Returns

cudaMemPool_t Handle to the underlying CUDA pool
