Detailed Description

A memory resource that allocates pinned (page-locked) memory using CUDA.

Member Function Documentation

do_allocate()

void * Mila::Dnn::Compute::CudaPinnedMemoryResource::do_allocate ( std::size_t  n, std::size_t  alignment = alignof(std::max_align_t)  )

inlineoverrideprotected

Allocates pinned memory.

Parameters

n	The size of the memory to allocate.
alignment	The alignment of the memory to allocate.

Returns

void* Pointer to the allocated memory.

Exceptions

std::bad_alloc

if the allocation fails.

do_deallocate()

void Mila::Dnn::Compute::CudaPinnedMemoryResource::do_deallocate ( void *  ptr, std::size_t  , std::size_t  alignment = alignof(std::max_align_t)  )

inlineoverrideprotected

Deallocates pinned memory.

Parameters

ptr	Pointer to the memory to deallocate.
size	The size of the memory to deallocate.
alignment	The alignment of the memory to deallocate.

do_is_equal()

bool Mila::Dnn::Compute::CudaPinnedMemoryResource::do_is_equal ( const std::pmr::memory_resource &  other ) const

inlineoverrideprotectednoexcept

Compares this memory resource with another for equality.

Parameters

other

The other memory resource to compare with.

Returns

true if the other memory resource is also a PinnedMemoryResource.

false otherwise.
