thread_alloc¶
View page sourceA Fast Multi-Threading Memory Allocator¶
Syntax¶
# include <cppad/thread_alloc.hpp>
Purpose¶
The C++ new and delete operators are thread safe,
but this means that a thread may have to wait for a lock on these operations.
Once memory is obtained for a thread, the thread_alloc memory
allocator keeps that memory available for the thread so that
it can be re-used without waiting for a lock.
All the CppAD memory allocations use this utility.
The free_available function should be used to return memory
to the system (once it is no longer required by a thread).
Include¶
The routines in sections below are defined by cppad/thread_alloc.hpp .
This file is included by
cppad/cppad.hpp , but it can also be included separately with out
the rest of the CppAD .
