摘要:

研究了求解非平稳高维线性规划问题的NSLP算法在集群计算系统上的可扩展性。分析是基于并行计算的BSF模型。BSF模型是在BSP和SPMD模型的基础上设计的一种新的并行计算模型。对NSLP算法和BSF模型进行了简要的描述。被认为是在一个BSF程序的形式NSLP算法的实现。在BSF代价度量的基础上,推导了NSLP算法可扩展性的上界,并对其并行效率进行了估计。描述了基于BSF骨架的NSLP算法实现。分析和实验获得的可扩展性估计的比较。

英文摘要:

The paper is devoted to a scalability study of the NSLP algorithm for solving non-stationary high-dimension linear programming problem on the cluster computing systems. The analysis is based on the BSF model of parallel computations. The BSF model is a new parallel computation model designed on the basis of BSP and SPMD models. The brief descriptions of the NSLP algorithm and the BSF model are given. The NSLP algorithm implementation in the form of a BSF program is considered. On the basis of the BSF cost metric, the upper bound of the NSLP algorithm scalability is derived and its parallel efficiency is estimated. NSLP algorithm implementation using BSF skeleton is described. A comparison of scalability estimations obtained analytically and experimentally is provided.
