[0051] Example 1——RAPTOR-M3G Parallel Performance Analysis

[0052] The transport calculations discussed in "Examples" were performed with RAPTOR-M3G running on a 20-processor computer cluster (ie, EAGLE-1). The cluster consists of 5 nodes with 2 dual-core dual-processor AMD Opteron 64-bit architecture. The total cluster memory (ie, RAM) available is 40Gbytes; the network interconnection is characterized by 1GBit / s (bit / s) bandwidth. With this hardware configuration, RAPTOR-M3G completes the entire 3D transport calculation for 2-loop PWR in about 106 minutes on 20 processors. No significant performance difference was observed using DTW, TW or ZW differential schemes.

[0053] Also, set up simple test problems to analyze the parallel performance of your code. The test problem consisted of a 50x50x50 cm box discretized on a uniform grid of 1 cm with uniformly distributed stationary sources. Use S with an energy group section set 8 Quadrature group and P0 isotropic scatter...

Abstract

The invention relates generally to a method for the calculation of radiation field distributions employing a new parallel 3-D radiation transport code and, a multi-processor computer architecture. The code solves algorithms using a domain decomposition approach. For example, angular and spatial domains can be partitioned into subsets and, the subsets can be independently allocated and processed.

Description

[0001] Cross References to Related Applications [0002] This provisional patent application claims priority to US Provisional Patent Application Serial No. 60 / 975,525, filed September 27, 2007. technical field [0003] The present invention relates generally to the calculation of radiation field distributions, and is particularly useful in predicting neutron-dosimetry responses to nuclear reactor cavities and internal components. Background technique [0004] Various methods can be used to obtain numerical solutions to the linear Boltzmann equation (LBE) for neutron and gamma radiation transport applications. Discrete ordinate method (S N ) is one such method used in particular in the field of nuclear engineering. S N The numerical solution of the equations is obtained by concurrent discretization of the phase space (ie, angle domain, space domain and energy domain). Concurrent discretization of the phase space leads to S N The large number of unknowns in the equation,...
