Detailed Description

template<typename T>
class libMesh::Threads::scalable_allocator< T >

Scalable allocator to be used in multithreaded code chunks which allocate a lot of dynamic memory.

Just use std::allocator when the Threading Building Blocks is absent.

This allocator can be faster than the std::allocator when there are multiple threads.
