NAME

       hbw::allocator<T>  -  The C++ allocator compatible with the C++ standard library allocator
       concepts
       Note: This is EXEPRIMENTAL API. The functionality  and  the  header  file  itself  can  be
       changed (including non-backward compatible changes), or remove.

SYNOPSIS

       #include <hbw_allocator.h>

       Link with -lmemkind

       hbw::allocator()
       template <class U>hbw::allocator<T>::allocator(const hbw::allocator<U>&)
       hbw::allocator<T>::~allocator()
       hbw::allocator<T>::pointer hbw::allocator<T>::address(hbw::allocator<T>::reference x)
       hbw::allocator<T>::const_pointer hbw::allocator<T>::address(hbw::allocator<T>::const_reference x)
       hbw::allocator<T>::pointer hbw::allocator<T>::allocate(hbw::allocator<T>::size_type n, const void * = 0)
       void hbw::allocator<T>::deallocate(hbw::allocator<T>::pointer p, hbw::allocator<T>::size_type n)
       hbw::allocator<T>::size_type hbw::allocator<T>::max_size()
       void hbw::allocator<T>::construct(hbw::allocator<T>::pointer p, const hbw::allocator<T>::value_type& val)
       void hbw::allocator<T>::destroy(hbw::allocator<T>::pointer p)

DESCRIPTION

       The  hbw::allocator<T>  is  intended  to  be  used  with  STL  containers to allocate high
       bandwidth memory. Memory management is based  on  hbwmalloc  (memkind  library),  enabling
       users to gain performance in multithreaded applications. Refer hbwmalloc(3) and memkind(3)
       man page for more details.

       All public member types and functions corresponds to standard library  allocator  concepts
       and definitions. The current implementation supports C++03 standard.

       Template arguments:
       T is an object type aliased by value_type.
       U is an object type.

       Note:
       hbw::allocator<T>::pointer   hbw::allocator<T>::allocate(hbw::allocator<T>::size_type   n,
       const  void  *  =  0)  allocates  high  bandwidth  memory   using   hbw_malloc().    Throw
       std::bad_alloc when:
            n = 0,
            n > max_size(),
            or there is not enough memory to satisfy the request.

       void              hbw::allocator<T>::deallocate(hbw::allocator<T>::pointer              p,
       hbw::allocator<T>::size_type n) deallocates memory associated  with  pointer  returned  by
       allocate() using hbw_free().

       To find out more about hbw_malloc() and hbw_free() read hbwmalloc(3) man page.

ERRORS

       The same as described in ERRORS section of hbwmalloc(3) man page.

NOTES

       The hbw::allocator<T> behavior depends on hbwmalloc heap management policy. To get and set
       the policy please use hbw_get_policy() and hbw_set_policy() respectively.
