Title : Stochastically Robust Resource Management in Heterogeneous Parallel Computing Systems

Abstract:
What does it mean for a computer system to be "robust"? How can robustness be described? How does one determine if a claim of robustness is true? How can one decide which of two systems is more robust? Parallel computing, communication, and information systems are typically heterogeneous mixtures of machines and networks. They are used to execute collections of tasks with diverse computational requirements. A critical research problem is how to allocate resources to tasks to optimize some performance objective. However, systems frequently have degraded performance due to uncertainties, such as unexpected machine failures, changes in system workload, or inaccurate estimates of system parameters. It is important for system performance to be robust against these uncertainties. To accomplish this, we present a stochastic model for deriving the robustness of a resource allocation. This model assumes that stochastic (experiential) information is available about these parameters whose actual values are uncertain. The robustness of a resource allocation is quantified as the probability that a user-specified level of system performance can be met. We show how to use this stochastic model to evaluate the robustness of resource assignments and to design resource management heuristics that produce robust allocations. The stochastic robustness analysis approach can be applied to a variety of computing and communication system environments, including parallel, distributed, cluster, grid, Internet, cloud, embedded, multicore, content distribution networks, wireless networks, and sensor networks. Furthermore, the robustness model is generally applicable to design problems throughout various scientific and engineering fields.

Title : Market-Oriented Cloud Computing: Vision, Hype, and Reality of Delivering Computing as the 5th Utility

Abstract:
Computing is being transformed to a model consisting of services that are commoditised and delivered in a manner similar to utilities such as water, electricity, gas, and telephony.  In such a model, users access services based on their requirements without regard to where the services are hosted.  Several computing paradigms have promised to deliver this utility computing vision and they include Grid computing, P2P computing, and more recently Cloud computing.  The latter term denotes the infrastructure as a “Cloud” in which businesses and users are able to access applications from anywhere in the world on demand. Cloud computing delivers infrastructure, platform, and software (application) as services, which are made available as subscription-based services in a pay-as-you-go model to consumers. These services in industry are respectively referred to as Infrastructure as a Service (Iaas), Platform as a Service (PaaS), and Software as a Service (SaaS).  To realize Cloud computing, vendors such as Amazon, HP, IBM, and Sun are starting to create and deploy Clouds in various locations around the world.  In addition, companies with global operations require faster response time, and thus save time by distributing workload requests to multiple Clouds in various locations at the same time.  This creates the need for establishing a computing atmosphere for dynamically interconnecting and provisioning Clouds from multiple domains within and across enterprises.  There are many challenges involved in creating such Clouds and Cloud interconnections.

This keynote talk (1) presents the 21st century vision of computing and identifies various IT paradigms promising to deliver the vision of computing utilities; (2) defines the architecture for creating market-oriented Clouds and computing atmosphere by leveraging technologies such as VMs; (3) provides thoughts on market-based resource management strategies that encompass both customer-driven service management and computational risk management to sustain SLA-oriented resource allocation; (4) presents the work carried out as part of our recent initiative in Cloud Computing, called as Megha: (i) Aneka, a software system for providing PaaS within private or public Clouds and supporting market-oriented resource management, (ii) internetworking of Clouds for dynamic creation of federated computing environments for scaling of elastic applications, (iii) creation of 3rd party Cloud brokering services for content delivery network and e-Science applications and their deployment on capabilities of IaaS providers such as Amazon and Nirvanix along with Grid mashups, and (iv) CloudSim supporting modelling and simulation of Clouds for performance studies; and (5) concludes with the need for convergence of competing IT paradigms for delivering our 21st century vision along with pathways for future research.

Title : MediaNets: Application Driven Next Generation IP Networks

Abstract:
Thanks to the explosive creation of multimedia contents, the pervasive adoption of multimedia coding standards, the ubiquitous access of multimedia services, the existing IP network infrastructure, with its best effort packet delivery mechanism, has started to suffer from performance degradation on emerging multimedia networking applications. This inadequacy problem is further deepened by the prevalence of last/first-mile wireless networking, such as Wi-Fi (IEEE 802.11 a/b/g/n), mobile WiMAX (IEEE 802.16e), and many wireless sensors and ad-hoc networks. To overcome the quality of service (QoS) challenges, the next generation IP networks have to be architected in a top-down manner, i.e., application driven layered protocol design. More specifically, based on the application media data, compression schemes are applied, the subsequent Network, MAC and PHY layered protocols are accordingly enhanced to reach the optimal performance. This is the fundamental concept behind the design of MediaNets. In this talk, I will address the QoS challenges specifically encountered in video over heterogeneous wireless broadband networks, and propose several application driven MediaNet solutions based on effective integration of APP and MAC/PHY layers. More specifically, the cross-layer congestion control for achieving airtime fairness of video streaming to maximize the link adaptation performance of Wi-Fi, the effective content wireless broadcasting over large scale distributed surveillance camera networks or vehicular ad-hoc networks, and the opportunistic multicast of scalable video live streaming over WiMAX.

Title : A New Era after the Convergence of Network Centric and Data Centric Computing

Abstract:
The Internet today has grown to an enormously large scale. Devices large and small are connected globally from anywhere on the earth.  Therefore, we can argue that we are in a network centric era. With the rapid advancement of technology, we now also have cheap and small devices like sensors and embedded processors with high computing power and large storage capacity.  These devices are designed to improve our daily life by monitoring our environment, collecting critical data, and executing special instructions. These devices have gradually become an essential and prominent part of our Internet.  Many imaging, audio and video data are converted from analog to digital. As a result, unprecedented amount of data is collected by these devices and are available via Internet. How to manage and look for the desired information becomes a great challenge.  Therefore, we can certainly also say that we are in a data centric era. In this talk, we will examine the challenges in the convergence of both network centric and data centric computing. At the same time, many emerging applications like service-oriented, security and real-time demand much better support than the current Internet can offer. How the future Internet should look like is still undetermined.  In this talk, we will present a vision of a content addressable future Internet that requires integrating the capabilities of networking with storage devices. What are the essential changes in data representation, information retrieval, storage systems and networking design will be discussed.  We believe an object-oriented intelligent storage is an essential part of the solution to this new computing and communication environment. We will also present a number of research projects that are currently carried out in Digital technology center Intelligent Storage Consortium (DISC) at University of Minnesota. These projects include data deduplication, power management in data centers, long-term data preservation, data/storage security/privacy,  and flash memory based solid state drives.
