It has been applied to the Swiss Light Source upgrade proposal (SLS-2) for the study of single bunch instabilities. However, an n-bunch simulation using mbtrack requires to run n+1 MPI processes. Therefore, a large scale computing cluster may be necessary to perform the simulation. In order to reduce the demands of computing resources for multi-bunch simulations, a CUDA version of mbtrack has been developed, in which the computations of mbtrack are offloaded to a graphics processing unit (GPU). With the mbtrack-cuda variant, multi-bunch simulations can now run in a standalone workstation equipped with an Nvidia graphics card for scientific computing. The implementation and benchmark of the mbtrack-cuda code together with the applications in the study of longitudinal instabilities for SLS-2 will be presented.
