During the approaching second Long Shutdown of the Large Hadron Collider (LHC) in 2019-2020, many technical improvements will occur in the accelerator complex, in the detector systems, and in the data acquisition systems. These will result in a huge increase of the number of expected collisions per second and as a consequence also the amount of measured data will grow rapidly. This period is the forerunner of the next generation of particle accelerators (HL-LHC, FCC), where we will accumulate experimental data in a higher rate than ever. In parallel, we need to improve also the numerical tools in order to be able to keep up the requirements of the high-precision era. The recently developed HIJING++ (Heavy Ion Jet Interaction Generator) will be the successor of the widely used original HIJING, developed almost three decades ago. While the old version was written in FORTRAN, the soon-to-be-published HIJING++ was completely rewritten in modern C++. During the development we keep in mind the requirements of the high-energy heavy-ion community: the new Monte Carlo software have a well designed modular framework, therefore any future improvement will be much easier. It contains all the improved physical models that were also present in its predecessor, but utilizing modern C++ features it also includes native thread-based parallelism, an easy-to-use analysis interface and a modular plugin system, which makes room for possible future improvements like GPU acceleration. In my talk, I present the current state of HIJING++ including the recent performance and benchmark tests.
