Load Balancing in Distributed Exascale Computing Based on Process Requirements

Abstract

In distributed Exascale systems, the occurrence of a dynamic and interactive nature changes the workload of the system's computing elements. Because of this, the load balancer needs to collect information on the system state. Activating the load balancer increases the runtime of the scientific application. While analyzing the impact of the dynamic and interactive nature on the load balancer functionality, this paper also attempts to provide a mathematical definition for load balancer based on the concept of dynamic and interactive nature. This makes it possible to describe and examine the load balancer functionality by considering the impacts of the dynamic and interactive nature. As a result, decisions can be made on the behavior of the load balancer when a dynamic and interactive nature occurs. According to the mentioned operational function, this paper has analyzed the load balancer's behavior in processes with a dynamic and interactive nature. The introduced operational function for the load balancer in this paper enables the management element to separate the requests of processes with a dynamic and interactive nature and normal processes that leads to redistribution.

Defining Parameters for the Oscillation Model of Load Flow of Global Activities in a Fully Distributed Exascale System

“…Here the resource space is a union of set of resources of the nodes where the resource can be in following types: File, Memory, I/O, Processor. The process requirement is a requirement of HPC process for resources (Shahrabi, S., Mollasalehi, F., Aliev, A. R., & Mousavi, E., 2018). HPC process scheduling is the overall queue of HPC processes.…”
