REDUCING THE EFFECT OF GLOBAL COMMUNICATION IN GMRES(M) AND CG ON PARALLEL distributed-memory computers
收藏 引用
APPLIED NUMERICAL MATHEMATICS 1995年 第4期18卷 441-459页
作者: DESTURLER, E VANDERVORST, HA UNIV UTRECHT INST MATH3508 TA UTRECHTNETHERLANDS SWISS FED INST TECHNOL ETHZIPSINTERDISCIPLINARY PROJECT CTR SUPERCOMPZURICHSWITZERLAND
In this paper we study possibilities for the reduction of communication overhead introduced by inner products in the iterative solution methods CG and GMRES(m). The performance of these methods on massively parallel d... 详细信息

On runtime parallel scheduling for processor load balancing
收藏 引用
IEEE TRANSACTIONS ON PARALLEL AND distributed SYSTEMS 1997年 第2期8卷 173-186页
作者: Wu, MY IEEE
Parallel scheduling is a new approach for load balancing. In parallel scheduling, all processors cooperate to schedule work. Parallel scheduling is able to accurately balance the load by using global load information ... 详细信息

AN IMPROVED SPECTRAL BISECTION ALGORITHM AND ITS APPLICATION TO DYNAMIC LOAD BALANCING
收藏 引用
PARALLEL COMPUTING 1995年 第1期21卷 29-48页
作者: VANDRIESSCHE, R ROOSE, D Department of Computer Science Katholieke Uniuersiteit Leuven Celestijnenlaan 200 A B-3001 Leuven Belgium
The efficient parallel execution of grid-oriented scientific calculations requires a partitioning of the grid that minimises both load imbalance and interprocessor communication. For unstructured static grids, good pa... 详细信息
