7 library allocator concepts
8 Note: This is EXEPRIMENTAL API. The functionality and the header file
9 itself can be changed (including non-backward compatible changes), or
10 remove.

29 The hbw::allocator<T> is intended to be used with STL containers to
30 allocate high bandwidth memory. Memory management is based on hbwmalloc
31 (memkind library), enabling users to gain performance in multithreaded
32 applications. Refer hbwmalloc(3) and memkind(3) man page for more
33 details.
34
35 All public member types and functions corresponds to standard library
36 allocator concepts and definitions. The current implementation supports
37 C++03 standard.
38
39 Template arguments:
40 T is an object type aliased by value_type.
41 U is an object type.
42
43 Note:
44 hbw::allocator<T>::pointer hbw::allocator<T>::allocate(hbw::alloca‐
45 tor<T>::size_type n, const void * = 0) allocates high bandwidth memory
46 using hbw_malloc(). Throw std::bad_alloc when:
47 n = 0,
48 n > max_size(),
49 or there is not enough memory to satisfy the request.
50
51
52 void hbw::allocator<T>::deallocate(hbw::allocator<T>::pointer p,
53 hbw::allocator<T>::size_type n) deallocates memory associated with
54 pointer returned by allocate() using hbw_free().
55
56 To find out more about hbw_malloc() and hbw_free() read hbwmalloc(3)
57 man page.

62 The same as described in ERRORS section of hbwmalloc(3) man page.
63
65 The hbw::allocator<T> behavior depends on hbwmalloc heap management
66 policy. To get and set the policy please use hbw_get_policy() and
67 hbw_set_policy() respectively.
