The reconstruction of charged particle trajectories is one of the most complex and CPU consuming parts of event processing in high energy experiments. At future hadron colliders such as the High-Luminosity Large Hadron Collider (HL-LHC) or the Future Circular Collider (FCC), the significantly increased number of simultaneous collisions will result in a much more challenging tracking environment. Concurrent algorithms exploiting modern computing architectures with many cores and accelerators are necessary to maintain and improve the tracking performance. Based on the tracking experience at LHC, the ACTS project is an attempt to encapsulate the current ATLAS software into a experiment-independent and framework-independent software designed for modern computing architectures. It provides a set of high-level track reconstruction tools which are agnostic to the details of the detection technologies and magnetic field configuration. The software has been fully tested for thread-safety to support parallel execution of the code and its data structures are optimized for vector operations to speed up linear algebra operations.
