Hua Wei · Journal of Guangxi Academy of Sciences · 2008
By analyzing the parallelism of LDLT Decomposition for Symmetric Matrix,a parallel algorithm of LDLT Decomposition for Symmetric Matrix is proposed and an OpenMP-based implementation with load-balancing for rough granularity is obtain.Then the parallel algorithm performance is tested.The numerical experiments show that the performance of algorithm is obviously improved in multicore processor system.
