Scheduling Complex Jobs in the Cloud – Challenges and Future Directions

 

Speaker: Helen Karatza

Professor Emeritus, Department of Informatics, Aristotle University of Thessaloniki, Greece

 

Abstract:

 

Cloud computing offers virtually unlimited computing resources on a pay-per-use approach to end users for running complex computationally intensive jobs without the problem of acquiring and maintaining expensive computers.

 However, there are important issues that must be addressed in order to exploit cloud computing full potential. This is mainly due to the scale of the cloud and the increasing number of cloud users and applications deployed in it. Critical issues are effective resource allocation, job scheduling, cost, quality of service, energy conservation. The scheduling algorithms must provide good performance to leasing cost ratio.

 Generally, job scheduling in large scale distributed computing systems is a challenging problem. Particularly important in cloud computing is the effective scheduling of complex real-time applications, taking into account not only the job response time but also the cost of the energy consumption for the cloud providers. Therefore, energy efficient scheduling strategies are required allowing for guarantees that the deadlines of complex jobs will be met.

 In this talk we will present recent research covering various concepts on complex jobs scheduling in the cloud and we will provide research directions and challenges in the cloud computing area.

Distributed Group Control of Autonomous Agents: Collective Robotics Use Case

 

Speaker: Vladimir Gorodetsky

Prof. of Computer Science, InfoWings, Russia

 

Abstract:

 

Despite the conceptual diversity of networked applications determining leading trends in the area of modern intelligent information technologies, the majority of them has many commons generalized within such frameworks as Internet of Things and/or Cyber-physical systems. Indeed, these frameworks were specifically developed to model and control of a wide class of modern applications composed of large number of intensively interacting heterogeneous (e.g. physical, virtual and social) autonomous objects with embedded computing and communication capabilities united in a network. The autonomous components of such applications operate in shared knowledge and data space and use intensive interactions to coordinate their individual behaviors and to conflict free control of shared resources and services. In the talk, this class of coordination and control is referred to as group control. Typical examples of group control applications are collective robotics, space-based distributed surveillance systems composed of small satellites, teams of unmanned aerial vehicles solving various distributed surveillance tasks for a number of customers, and many others.

The talk proposes a classification of group control tasks, analyses the peculiarities and common properties of various related applications and shows that the traditionally used purely knowledge-based (KB) paradigm of Artificial Intelligence (AI) does not quite fit to model the applications in question and needs an extension with some behavior-based (BB) concepts and models.

The first focus of the talk is on the BB group control problem statement, analysis of some BB-related basis concepts, e.g. behavior pattern, group behavior scenario, situation, situation assessment and situation awareness, among others. These concepts and corresponding models are ignored in ontologies of the KB paradigm of artificial intelligence. The second focus is on generic formal model of group control specifying the group behavior of autonomous agents in terms of a network of interacting state machines with inner states implementing predefined group control protocols (distributed algorithms), in typical use cases.

The introduced BB-concepts and proposed distributed algorithms of group control formalized as a network of autonomous agents (state machines) are illustrated by a case study implementing a group of interacting robots performing jointly autonomous assembly production without intervention of a human.

In conclusion, a sketch of a roadmap of future research and development in the area of group control is outlined.
