INFLUENCE OF USING MULTIPLE MPI CLUSTER NETWORK LINKS TO THE EXECUTION SPEED OF THE FINITE STRIP METHOD CONSTRUCTION ANALYSIS PROGRAM

Abstract

Communication links between the nodes of the MPI cluster sometimes present a bottleneck in its functioning. This problem is more or less alleviated by speeding up the network links and one of the ways to achieve this is the use of multiple network links. This paper compares finite strip method construction analysis program execution times on MPI cluster when nodes use single network interface, two network interfaces and two aggregated network interfaces, varying the number of nodes types of input and the types of algorithms. Analysis, which is provided at the end, shows advantages and faults of using multiple network links, when is it suitable to use them and when and under which conditions it gives the best results.
