MULTITHREADING
==============
.. _MULTITHREADING_:

.. kernel version: 

Multithreading support in the mathematical kernel implies:

- Use of parallel calculations in the kernel.
- Support of multithreading in user applications.

The mathematical kernel implements mechanisms that enable
thread-safe use of the kernel interfaces in parallel calculations.

To establish internal multithreading the kernel uses the **OpenMP**
technology.

The main parallel operations in the kernel include (but are not limited
to):

- Construction of planar projections
- Calculation of polygonal meshes
- Calculation of mass-inertia properties
- Converter operations

If an interface implementation employs parallel calculations, then the
corresponding information is included in the comments to the interface.

To ensure thread-safe use of kernel interfaces in multithreaded
applications, synchronization objects based on system mechanisms are
used.
