Constructor & Destructor Documentation

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. References MAX_CUDA_DEVICES.

Member Function Documentation

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, Dlist::index(), CudaDevices::malloc(), and n.

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. References Dlist::index(), and n.

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. References i.

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. References CudaDevices::free(), and n.
