Allocators - syclreference.com

Type	Definition	Notes
`buffer_allocator`	cl::sycl::default_allocator
`default_allocator`	detail::aligned_mem::aligned_allocator	Default SYCL allocator uses the aligned allocated, but also removes the constness of the type.
`image_allocator`	cl::sycl::default_allocator

aligned_allocator	An allocator that can allocate memory aligned to a certain alignment boundary with the final allocated size a multiple of some required size.
base_allocator	Forward calls from the runtime-side to the user-defined allocator. This allows the internal runtime methods to call the user-defined typed allocator without passing the template tag. The isMapAllocator is used internally to determine if the allocator is a map-based one, which will enable some optimizations if possible.
make_base_allocator<T, AllocatorT>	Creates a pointer to the internal base allocator structure from an instance of an user-defined allocator class.
wrapped_allocator<AllocatorT>	Typed derived class for a base allocator that holds an instance to an user-defined allocator.

allocate	Allocates aligned data.
cast_base_allocator	Retrieves the original user-supplied allocator from the stored detail allocator object.
clone_data	MISSING
deallocate	Deallocates aligned data.
get_aligned_size	Calculates the size that needs to be allocated for the memory to be properly aligned.
get_default_alignment	Retrieves the default alignment boundary
get_default_required_size_multiplier	Retrieves the default required size multiplier
is_aligned	Checks whether the pointer points to aligned data
