System Requirements
-------------------

For CPU
=======

.. rubric:: Operating systems

The last two versions of the following operating systems:

- **Linux**\*
- **Windows**\* and **Windows\* Server**
- **macOS**\*

.. rubric:: Hardware platforms

- All processors with x86 architecture

.. note::
    Your processor must support at least one of SSE2, SSE4.2, AVX2, AVX512 instruction sets.

.. note::
