This paper describes a parallel implementation of our practical particle-in-cell (PIC) simulator with the OhHelp dynamic load-balancing algorithm. Although the code parallelization is based on simple block domain decomposition, OhHelp accomplishes load balancing and thus the scalability in terms of the number of particles by making each computation node help another heavily loaded node. In addition...
This paper develops a parallel fast multipole method specialized for uniform brick elements to achieve large-scale micromagnetic simulations of a practical perpendicular recording head within acceptable computation time. In highly parallel computation, it is indispensable to equally distribute the computing load among processes so as to obtain the good parallel speedup. The load balancing technique...
