This paper presents a new approach to parallelize 3D lattice Monte Carlo algorithms used in the numerical simulation of polymer on ZiQiang 2000-a cluster of symmetric multiprocessors(SMPs).The combined load for cell and energy calculations over the time step is balanced together to form a single spatial decomposition.Basic aspects and strategies of running Monte Carlo calculations on parallel computers are studied.Different steps involved in porting the software on a parallel architecture based on ZiQiang 2000 running under Linux and MPI are described briefly.It is found that parallelization becomes more advantageous when either the lattice is very large or the model contains many cells and chains. 相似文献

In this paper,a novel hybrid method is presented for finding global optimization of an objective function.Based on the interval computation,this hybrid method combines interval deterministic method and stochastic evolution method.It can find global optimization quickly while ensuring the deterministic and stability of the algorithm.When using interval computation,extra width constraints accuracy of interval computation results.In this paper,a splitting method to reduce the extra width is introduced.This met... 相似文献
