This paper presents a parallelization of the Constraint Programming solver OR-Tools, using the parallel framework Bobpp. The principle of the parallelization is to assign one sequential OR-Tools solver per core and to communicate work or nodes using the Bobpp global priority queue. As usual the communication or migration of work between solvers is a kind of Work Stealing. But here we have to deal...
Simulations of colliding galaxies or fluid dynamics at immersed flexible boundaries are most accurately and efficiently accomplished using the adaptive fast multipole method (AFMM) to solve an underlying n-body problem whose localized density varies with the time-dependent evolution of the system under study. Parallelization of the AFMM presents a challenging load balancing problem that must be addressed...
