Abstract:
Rigorous three-dimensional (3D) slope stability analysis is time consuming and takes major computer resources. To speed up the computation so that engineers can get results within shorter time is a bottleneck problem. In this study, we propose to speed up 3D slope stability analysis program with “OpenMP” which is tested to be effective, by using parallel processing. Further, the authors demonstrate that calculation time by using OpenMP becomes much less than before and this kind of parallel processing is not difficult to be used for general problems. Through the analysis, we have also discovered the number of computers' CPU has a great impact on the performance of the 3-D slope stability program. There are various precautions in using parallel processing, or else there will be conflict of memory address and changes of values by different threads of processes.
