cuda::experimental::managed_memory_pool

struct managed_memory_pool : public cuda::experimental::managed_memory_resource

Stream ordered memory resource

managed_memory_pool allocates managed memory using cudaMallocFromPoolAsync / cudaFreeAsync for allocation/deallocation. A When constructed it creates an underlying c cudaMemPool_t with the allocation type set to c cudaMemAllocationTypeManaged and owns it.

Public Types

using reference_type = managed_memory_resource

using default_queries = ::cuda::mr::properties_list<::cuda::mr::device_accessible, ::cuda::mr::host_accessible>

Public Functions

inline managed_memory_pool(memory_pool_properties __properties = {})

Constructs a managed_memory_pool with optional properties.

Properties include the initial pool size and the release threshold. If the pool size grows beyond the release threshold, unused memory held by the pool will be released at the next synchronization event.

Parameters:

__properties – Optional, additional properties of the pool to be created.
