Description
In this paper, parallelization for CP calculation and multigroup flux computation are presented. Implementation of acceleration and neutron rebalancing strategies is also investigated. Particular techniques pertinent to the two-step energy/space iterative process of solving a multigroup transport equation are described. The parallel performance is studied in cases where the cyclic tracking technique is used to integrate CP. Parallelization is achieved by distributing either different energy groups or different regions on set of processors. These algorithms were tested on 4 processors IBM SP-2, 4 processors SPARC 2000 as well as 8 processors SPARC 1000 using the public domain PVM library. Typical run times are provided for unit cell calculations. (author)
