cuda::experimental::pinned_memory_pool_ref

class pinned_memory_pool_ref : public cuda::experimental::__memory_resource_base

Stream ordered host pinned memory pool

pinned_memory_pool_ref allocates pinned memory using cudaMallocFromPoolAsync / cudaFreeAsync for allocation/deallocation. A pinned_memory_pool_ref is a thin wrapper around a c cudaMemPool_t with the location type set to c cudaMemLocationTypeHost or c cudaMemLocationTypeHostNuma.

Warning

pinned_memory_pool_ref does not own the pool and it is the responsibility of the user to ensure that the lifetime of the pool exceeds the lifetime of the pinned_memory_pool_ref.
