A Multi-Group Parallel Method for the 2-D Neutron Transport Equation
HU Qing-feng · Computer Engineering and Science · 2006
The 2-D neutron transport equation is one of the most important partial differential equations used in scientific computing. Partitioning data and computing by group,we get a load balancing algorithm. Analyses indicate that generally the degree of load balancing is very much close to one. This excellently solves the problems of load imbalance and low parallel efficiency ,and we get linear speedups on a PC cluster with 12 CPUs.
