Design and Analysis of Multi-core Parallel Model for BP Inversion of Gravity and Magnetic Anomalies

摘要：

During the procedure of the gravity and magnetic 3-D inversion with large scale data,BP inversion algorithm will cause large command of computation and storage.This paper gives an efficient solution based on the method of the multi-core parallel model and equivalent storage.That is,equivalent storage principle is used upon the position function of physical property units to lower its storage cost,while a parallel model of BP inversion algorithm is designed to increase its computation efficiency.Experimental results shows that this methods storage reduces from O(kn4) to O(kn2) on an eight-core sever,and gets a speedup of 7.628,which is very close to the theoretical value of 8.
