Abstract:

The explosive number of smartphones with ever growing computing and sensing capabilities have brought a paradigm shift to many traditional domains of the computing field. Smartphone users nowadays gain access to unprecedented possibilities, knowledge and power due to a diverse landscape of applications. Developers on the other hand are challenged with a fragmented mobile landscape that is extremely dynamic to changes in both hardware and software. Re-programming smartphones and instrumenting them for application testing and data gathering at scale is currently a tedious and time-consuming process that poses significant logistical challenges.

In this talk, we present the abstractions comprising SmartLab, a Mobile Infrastructure as a Service cloud we have developed and deployed at the University of Cyprus. In SmartLab, an intuitive web-based interface supplies a variety of complex mobile management utilities that provide fine-grained and low-level control over real smartphones, e.g., usage of networking, storage and sensors as well as automated mockup executions. We present our research experiences from using SmartLab in different research settings as well as our envisioned future scenarios for urban-scale deployment, federation issues and security studies. My talk will be succeeded by a summary of related mobile data management research efforts, namely Anyplace, which is our in-house indoor localization and navigation service; and Rayzit, which is our award-winning location-based crowd messaging service.

13:00
Library, Argentinierstrasse 8 / E184-1, 3rd floor

Abstract:

More and more smart energy measurement devices (e.g., smart meters and smart plugs) are being deployed in households and office buildings worldwide to collect fine-grained power consumption data. A wide range of novel energy-based services can be realized based on these data, e.g., emitting recommendations how to save energy or providing means to increase comfort. In this talk, I will outline selected user-centric services based on energy monitoring which are enabled by the availability of high-resolution power consumption data. I will also shed light on how power consumption data can reveal the nature of operating appliances and their mode of operation at high accuracy. A briefly discussion of the resulting threats to user privacy and insights gained from a lightweight local solution to mitigate these threats by eliminating characteristic consumption patterns from the data will conclude my presentation.

Towards a Unified View of Elasticity

Dr. Srikumar Venugopal

University of New South Wales (Sydney)

Date:
Time:
Place:

Friday, Dec 13th 2013
11:00
Library, Argentinierstrasse 8 / E184-1, 3rd floor

Abstract: The defining feature of cloud computing is elasticity, or the ability to add and remove resources at will. Elasticity has created interesting opportunites for research into resource provisioning, fault tolerance, scalability and the like. However, most of the current research into elasticity has focussed on linear scaling of application logic where management of state information is delegated to a persistence layer. There has been less emphasis on the impact of elasticity on the persistence layer and how application state can be effectively managed during elastic operations.

This talk will present some of the recent work in my group in UNSW on elastic scaling, both for application layer and for the persistence layer. I will end the talk with some thoughts on how we can unify elasticity across the application stack.

Date:
Time:
Place:

Friday, Sept 13th 2013
10:00
Library, Argentinierstrasse 8 / E184-1, 3rd floor

Abstract:

With an estimated market volume of US$ 130 billion and double-figure growth rates, cloud computing is on the path to change many aspects of our digital lives. We consider the question of potential benefits and open challenges when bringing BPM into the cloud, such as (i) how can BPM benefit from the cloud, (ii) what should BPM in the cloud look like, and (iii) what can BPM bring to cloud computing practices? In this talk I will present three works around those questions, namely (a.) end-user-friendly process modelling in the cloud, (b.) process-aware auto-scaling of cloud resources, and (c.) process mining for error diagnostics in cloud management processes -- with an emphasis on (c.). The talk will close with a presentation of a number of open challenges

11:00
Library, Argentinierstrasse 8 / E184-1, 3rd floor

Abstract:

The problem of strategic alignment is regarded as one of the grand challenges in management. In this talk, I will argue that an algorithmic approach to the analysis of the alignment of services with organizational strategy is possible, and will demonstrate it via the ServAlign tool. I will argue that the use of such a tool is an important basis for enterprise rationalization via strategic dashboards. I will also argue that a novel take on big data enables the acquisition of strategic know-how.

Library, Argentinierstrasse 8 / E184-1, 3rd floor

This talk has been cancelled

Abstract:

In the presence of limited resources constant computing power growth requires effective utilization of computing resources. The problem of effective scheduling becomes highly relevant. Numerous heuristics (like min-min, xsufferage, genetic algorithms etc.) provide relatively good solution for a NP-hard problem of scheduling. Although most of the published heuristics have two issues. First of all, many of such algorithms do not consider inter-processor communication which becomes highly important in modern computing. Secondly, many scheduling heuristics do not guarantee the quality of scheduling whatsoever. Based on models of C.Leiserson and V.Vl. Voevodin the author builds a new mathematical model of scheduling in distributed systems with active data transfers. The author considers different types of independent tasks and different types of distributed systems and for all the scenarios presents worst case estimates of quality of scheduling as a function of task and distributed environment parameters. These estimates demonstrate the influence of communication and sizes of independent tasks on the quality of scheduling. For instance, the Author shows how the connection latency plays important role in the scheduling. Also the author has deployed a distributed system on small cluster of 20 nodes and demonstrated applications of the method to estimate the quality of scheduling. The methods can be applied to calculate the quality of scheduling for different present cases including 1)scheduling of independent tasks in MapReduce and 2)scheduling in the presence of horizontal scaling (like in elastic cloud EC2).

Talk: Towards Real-Time Control in Complex Logistics Chains

Paul Grefen & Remco Dijkman

Eindhoven University of Technology

Date:
Time:
Place:

Thursday, January 17th 2013
11:00
Library, Argentinierstrasse 8 / E184-1, 3rd floor

Abstract:

In this presentation, we address the topic of support for real-time control in complex, multi-modal logistics chains. We elaborate control models and show how these can be mapped to information system infrastructures. The presentation consists of two parts. In the first part, Paul Grefen presents the development of an information-based control model for supply chains. He shows how this control model can be mapped to shared IT infrastructure, such as service clouds. In the second part of the presentation, Remco Dijkman presents the GET Service European project, which aims at a practical implementation of a specific version of the control model around an integrated service bus. In this project, aggregation of large volumes of diverse real-time, transport-related information is used to provide input for both static and dynamic planning of complex logistics processes. The ultimate goal is to support on-the-fly, drag-and-drop reconfiguration of logistics processes using the parallel availability of multiple transport modalities (i.e., using synchro-modality).

Talk: Kriging based Self-Adaptive Controllers for the Cloud

Alessio Gambi

Univ. of Lugano, Switzerland, [Homepage]

Date:
Time:
Place:

Thursday, January 12th 2012
14:00
Library, Argentinierstrasse 8 / E184-1, 3rd floor

Abstract:

In the context of Cloud computing, Service Providers (SP) can access resources "on-demand" and dynamically scale their elastic applications; in this way, SPs can reduce the need of system over-sizing and provide guarantees about applications QoS. To properly achieve this, SPs must decide on when, what and how to scale their systems.

Dynamic changes in operating conditions, and the complexity of the relations between system behaviors and system configurations may reduce the effectiveness of statically defined solutions. Model based self-adaptive controllers seem to be more promising solutions as they were originally proposed to deal with complex systems, emerging behaviors, and dynamic environments, and because they can autonomously learn from past experience and adapt to the actual operating conditions.

In this talk, I discuss the design of self-adaptive controllers based on a particular black-box surrogate model, named Kriging model. Kriging models are the mathematical tools that controllers use to capture the relations between the QoS of the virtualized systems, the incoming workload and the system configuration, and to support their planning activities; the models are maintained up-to-date by the controllers during the runtime activities.

Guest lecture: Cooperative Infrastructure Provisioning in Social Clouds

Christian Haas

Karlsruhe Institute of Technology (KIT), Germany

Date:
Time:
Place:

Wednesday, October 5th 2011
16:00
seminar room Argentinierstrasse

Abstract:

In order to run a platform like a Social Cloud, a certain quantity of resources is necessary to facilitate the platform itself and the services that enable the basic operation of the platform. For example, because users can share and trade resources using different (economic) protocols, the matching of demand to supply results in the calculation of one or more allocations, and requires a form of computational infrastructure to facilitate this.

Hence, this talk discusses how such infrastructure resources can be provided by the users of the Social Cloud itself, rather than from a central entity. An economic co-operative sharing model of users is formulated, where the platform itself and its functionality are provided and owned by the users. In addition, the efficiency and performance of such a model depending on incentive schemes and users' characteristics is studied.

Guest lecture: Consensus in distributed systems

Rui Oliveira

University do Minho, Braga, Portugal

Date:
Time:
Place:

Thursday, April 14th 2011
14:15
EI1, Gusshausstrasse 25

Abstract:

This guest lecture is part of the master level lecture "Advanced Distributed Systems".

It may be of particular interest for PhD students working on distribution aspects, as consensus is *the* fundamental problem of distributed systems and many proofs exists under what conditions consensus can be deterministically solved - and when not (e.g., two army/coordinated attack problem, byzantine generals, muddy children/jealous amazons, etc...).

The lecture will explain the basic problem, sketch the FLP proof idea and motivate the idea of failure detectors.

Talk Invitation: Process Reliability in Service-oriented Architectures

Dr. Stefan Schulte

TU Darmstadt

Date:
Time:
Place:

Friday, April 1st 2011
13:00
Library, Argentinierstrasse 8 / E184-1, 3rd floor

Abstract:

After a brief description of my research background, this talk will focus on my former work on process reliability in Service-oriented Architectures. The creation of business processes by composing loosely coupled services to (complex) workflows is one of the major application scenarios of Service-oriented Computing. As a result of the ongoing success of Web service technologies, services can be purchased from external providers. In a future "Internet of Services", functionally equivalent services which provide different cost and quality levels will be available and can be selected by a service consumer in order to execute the different steps of a workflow. Furthermore, the existence of functionally equivalent services allows replacing a service if it does not meet its guaranteed service levels. In this talk, I will present work originating from the BMBF-funded project SoKNOS (Service-Oriented ArchiteCtures Supporting Networks of Public Security) which addresses the selection of services based on user-defined constraints, the monitoring of the workflow execution, and the re-planning of service-based workflows (if necessary).
