Changes

TBB provides memory allocation just like in STL via the '''std::allocater''' template class. Where TBB's allocater though improves, is through its expanded support for common issues experienced in parallel programming. These allocaters are called '''scalable_allocater<type>''' and '''cache_aligned_allocater<type>''' and ensure that issues like '''Scalability''' and '''False Sharing''' performance problems are reduced.

When working in parallel, several threads may be required to access shared memory which causes a performance slow down from forcing a single thread to allocate memory while other threads are required to wait. Intel describes this issue in parallel programming as '''Scalability''' and answers the issue with '''scalable_allocater<type>''' which permits concurrent memory allocation and is considered ideal for "''programs the rapidly allocate and free memory''".
