Efficient parallel inversion using the Neighbourhood Algorithm

Rickwood, Peter; Sambridge, Malcolm


Issues controlling efficient parallel implementations of a popular direct search inversion algorithm are analyzed and discussed. A naive parallelization of a particular method, the Neighbourhood parameter search algorithm, leads to inefficient use of parallel architecture through lack of scalability and intolerance to hardware faults. These factors are quantified, and their origins are explained. A reformulation of the algorithm leads to dramatically improved performance when the cost of the...[Show more]
