  This paper introduces TVB C++, a streamlined and fast C++ Back-End for The
Virtual Brain (TVB), a renowned platform and a benchmark tool for full-brain
simulation. TVB C++ is engineered with speed as a primary focus while retaining
the flexibility and ease of use characteristic of the original TVB platform.
Positioned as a complementary tool, TVB serves as a prototyping platform,
whereas TVB C++ becomes indispensable when performance is paramount,
particularly for large-scale simulations and leveraging advanced computation
facilities like supercomputers. Developed as a TVB-compatible Back-End, TVB C++
seamlessly integrates with the original TVB implementation, facilitating
effortless usage. Users can easily configure TVB C++ to execute the same code
as in TVB but with enhanced performance and parallelism capabilities.
