cuda::shared_pinned_memory_pool

class shared_pinned_memory_pool : public cuda::__shared_memory_pool_base<shared_pinned_memory_pool>

Shared pinned memory pool

shared_pinned_memory_pool provides shared ownership of a pinned memory pool. It is copyable and each copy shares the same underlying cudaMemPool_t via reference counting. This makes it usable with any_resource and other contexts that require copyable resources.

inline explicit shared_pinned_memory_pool(no_init_t) noexcept

Constructs an empty shared pinned memory pool.

inline explicit shared_pinned_memory_pool(

memory_pool_properties __properties = {}

)

Constructs a shared pinned memory pool.

Parameters:

__properties – Optional pool creation properties.

inline explicit shared_pinned_memory_pool(

int __numa_id,

memory_pool_properties __properties = {}

)

Constructs a shared pinned memory pool on a specific NUMA node.

Parameters:
