Modification of the ILU-Method for Enhanced Parallel Efficiency, shown to enable both vectorization and a coarser granularity of parallelism. Experimental results demonstrate both the numerical behaviour of the schemes and the improvements in efficiency obtained on two DMMP parallel computers.作者: meretricious 時間: 2025-3-22 04:17
Relaxed ILU Preconditioning for the CG Solution of a Singular Boundary Value Problem for Pressure,this problem, producing a linear system of equations whose coefficient matrix is symmetric positive semidefinite. We give an account of our experience with solving this system by the conjugate gradient method with relaxed ILU preconditioning. Particular attention is given to the effect of the nonuniformity of the grid.作者: 兵團 時間: 2025-3-22 04:46 作者: 套索 時間: 2025-3-22 11:40
Preconditioning of Blockstructured Linear Systems with Block ILU on Parallel Computers,lved on a parallel computer.

Incomplete Factorizations with S/P and Modified S/P Consistently Ordered M-Factors,ete factorizations with (M-matrix) triangular factors whose graphs are S/P consistently ordered have attractive properties which have been analysed. The conclusion of our analysis is that in such cases, the submatrix determined by the nodes without successors should be factored exactly.作者: 欲望 時間: 2025-3-23 02:48 作者: 行為 時間: 2025-3-23 07:43 作者: Subdue 時間: 2025-3-23 11:25

Modification of the ILU-Method for Enhanced Parallel Efficiency,parallelization of this method is possible when the dimension of the processor array is less than that of the problem. However, in terms of parallelism, ILU methods suffer from two disadvantages: the procedure is not well vectorizable and it has a very fine granularity, making it unsuitable for some作者: 協(xié)迫 時間: 2025-3-27 00:47 作者: 生來 時間: 2025-3-27 02:50 作者: ANN 時間: 2025-3-27 07:13
