Constructor & Destructor Documentation

NumaAllocator()

template<class T >

Kaskade::NumaAllocator< T >::NumaAllocator ( int  node )

inline

Construct an allocator for allocating on the given NUMA node.

Parameters

node	the NUMA node on which to allocate the memory. This has to be less than NumaThreadPool::instance().nodes(). For negative values, the memory is allocated in interleaved mode.

Definition at line 681 of file threading.hh.

address() [1/2]

template<class T >

const_pointer Kaskade::NumaAllocator< T >::address ( const_reference  x ) const

inline

Definition at line 698 of file threading.hh.

address() [2/2]

template<class T >

pointer Kaskade::NumaAllocator< T >::address ( reference  x ) const

inline

Definition at line 693 of file threading.hh.

allocate()

template<class T >

pointer Kaskade::NumaAllocator< T >::allocate ( size_type  n, std::allocator< void >::const_pointer  = 0  )

inline

Allocates the requested amount of memory.

Parameters

n	number of objects of type T

If

• n == 0, a null pointer is returned. If the request cannot be fulfilled, std::bad_alloc is thrown.

template<class T >

template<class U >

void Kaskade::NumaAllocator< T >::destroy ( U *  p )

inline

Definition at line 737 of file threading.hh.

max_size()

template<class T >

node()

template<class T >

int Kaskade::NumaAllocator< T >::node ( ) const

inline

Reports the node on which we allocate.

operator==()

template<class T >

template<class U >

bool Kaskade::NumaAllocator< T >::operator== ( NumaAllocator< U > const &  other ) const

inline

comparison for equality

Allocators compare equal, if they allocate on the same NUMA node.
