Abstract :
The dynamic aperture represents the volume in phase-space in which stable motion occurs. This is a key parameter to define the performance of a circular machine. The computation of this volume requires CPU-intense numerical simulations. In this paper, some original parallel algorithms to speed-up the evaluation of the dynamic aperture are presented. A detailed analysis of different algorithms is carried out. Furthermore, the dependence of the CPU-time on the phase-space parameters as well as the load balancing of the proposed techniques are studied
