Vectorization of MORSE-DD Code.
1987-01-01

We have vectorized the multi-group Monte Carlo code MORSE-DD. The Monte Carlo method is very powerful to simulate the motion of particles. However the Monte Carlo codes spend much calculation time, it is required to accelerate the codes by using vector ...

ON THE ACCELERATION OF MONTE CARLO CALCULATIONS
1959-06-01

The two ways in which Monte Carlo computer calculations may be accelerated are discussed. The two types of acceleration, each of which may be considered independent of the other, are called subroutine acceleration and convergence acceleration. Subroutine ...

Post-processing of Monte Carlo simulations for rapid BNCT sourceoptimization studies.
2000-01-01

A great advantage of some neutron sources, such as accelerator-produced sources, is that they can be tuned to produce different spectra. Unfortunately, optimization studies are often time-consuming and difficult, as they require a lengthy Monte Carlo simu...

Implicit Monte Carlo diffusion - an acceleration method for Monte Carlo time dependent radiative transfer simulations
2000-10-01

We present a method for accelerating time dependent Monte Carlo radiative transfer calculations by using a discretization of the diffusion equation to calculate probabilities that are used to advance particles in regions with small mean free path. The method is demonstrated on problems with on 1 and 2 dimensional orthogonal grids. It ...

Application of coarse-mesh rebalance acceleration to Monte Carlo eigenvalue problems
1976-04-01

The coarse-mesh rebalance method is adopted in Monte Carlo schemes for aiming at accelerating the convergence of a source iteration process to obtain the eigenvalue of a nuclear reactor system. At every completion of the Monte Carlo game for one batch of neutron histories, the scaling ...
