Parallel Simulation of Ion Recombination
Ion recombination in nonpolar liquids is an important problem in radiation chemistry. We have designed and implemented a parallel Monte Carlo simulation for this computationally-intensive task on a network of workstations. The main problem with parallelizing this application is that the amount of wo...
