Detailed Description

Un-typesafe base class for maintaining a free-list memory pool.

Definition at line 49 of file cudafreelist.H.

rutz::cuda_free_list_base::cuda_free_list_base ( std::size_t size_check )

Construct an (empty) free list.

All objects from this list must be of size size_check.

Definition at line 42 of file cudafreelist.C.

std::size_t rutz::cuda_free_list_base::alloc_size ( ) const [inline]

Query the chunk size that this freelist is for.

Definition at line 94 of file cudafreelist.H.

void * rutz::cuda_free_list_base::allocate	(	std::size_t	bytes,
		int	dev
	)

Allocate space for a new object.

If there are chunks available in the free list, one of those is returned; otherwise new memory is allocated with malloc() or equivalent.

Definition at line 52 of file cudafreelist.C.

References ASSERT.

void rutz::cuda_free_list_base::deallocate	(	void *	space,
		int	dev
	)

Return an object to the free list.

Definition at line 73 of file cudafreelist.C.

std::size_t rutz::cuda_free_list_base::num_allocations ( int dev ) [inline]

Query how many allocations have been made.

Definition at line 97 of file cudafreelist.H.

void rutz::cuda_free_list_base::release_free_nodes ( )

Release all nodes currently on the free list (e.g. to conserve memory).

Definition at line 119 of file cudafreelist.C.
