Challenges of Execution Trend in Distributed Exascale System

In computing systems, the execution trend pattern for the application indicates the executing trend of the application based on the application features, as well as the ability of the system elements to reduce the response time. In traditional computing systems, due to the clear nature of the application, system designer is able to determine its implementation pattern when designing the system and to establish this execution pattern at runtime by changing system manager’s constituent elements. In distributed Exascale systems, the occurrence of a dynamic and interactive nature changes the processes and system elements. While investigating the effect of the dynamic and interactive nature of distributed Exascale systems on determining the execution pattern, this paper also discusses the challenges that exist to establish this concept in distributed Exascale systems. It also states why the determinant element of execution pattern is required in system manager and suggests some strategies to manage these challenges in distributed Exascale systems.
