Which Dynamic Libraries to Use
==============================
The template ``scalable_allocator<T>`` requires the |full_name|
scalable memory allocator library as
described in **Scalable Memory Allocator**. It does not require the
oneTBB general library, and can be used independently of the rest of
oneTBB.
The templates ``tbb_allocator<T>`` and ``cache_aligned_allocator<T>``
use the scalable allocator library if it is present otherwise it reverts
to using ``malloc`` and ``free``. Thus, you can use these templates even
in applications that choose to omit the scalable memory allocator
library.
The rest of |full_name| can be used
with or without the oneTBB scalable memory allocator library.
