Yet a swell in media and analyst coverage, plus a proliferation in cloud computing providers and marketing messages, has resulted in a great deal of confusion about what the term “cloud computing” really means. For example, some providers look at cloud computing as way to provide compute or storage capacity as a service, provi- sioned from a parallel, on-demand processing platform that leverages economies of scale. Others may equate cloud com- puting with software as a service, a delivery model for making applications available over the Internet. IT analysts view cloud computing from the perspective of variable pricing without long-term commitments and massive elastic scaling of services. IT leaders look at cloud as an infrastructure architecture alternative...

...Level 3 and Cloud Computing Level 3 Shapes the Cloud Any Cloud Computing application or service exhibits two characteristics. First it uses virtualization to decouple the end user from the actual service and second it employs a pay-as-you-go business model. Virtualization is the key technology, while pay-as-you-go provides the business flexibility. Virtualization let’s users take advantage of a service without the concern of owning or managing the actual physical resources used to provide the service. From a business perspective this allows IT departments to take advantage of a multitude of technologies to cost optimize the way they deliver services. Regardless of the type of virtualization employed, one simple fact remains, the user must still be connected to the service via a very ‘un-virtual’, real, physical connection. The connection is the ‘cloud’ of cloud computing. Level 3 builds these clouds. Application Performance Enables Network Performance The network is often taken for granted, but in the realm of Cloud Computing, the network has become part of the application. IT managers want to gain the benefits of moving to the cloud, but they must be assured that their customers, the users of the cloud, will have a consistent application experience. By working with Level 3 those IT managers can be assured that we will match their applications to the right type of cloud. We have no vested interest in driving one type of connection over any other. We have no cloud...

...Autonomic Computing: An Overview Manish Parashar1 and Salim Hariri2 The Applied Software Systems Laboratory, Rutgers University, Piscataway NJ, USA 2 High Performance Distributed Computing Laboratory, University of Arizona, Tucson, AZ, USA parashar@caip.rutgers.edu, hariri@ece.arizona.edu 1 Abstract. The increasing scale complexity, heterogeneity and dynamism of networks, systems and applications have made our computational and information infrastructure brittle, unmanageable and insecure. This has necessitated the investigation of an alternate paradigm for system and application design, which is based on strategies used by biological systems to deal with similar challenges – a vision that has been referred to as autonomic computing. The overarching goal of autonomic computing is to realize computer and software systems and applications that can manage themselves in accordance with high-level guidance from humans. Meeting the grand challenges of autonomic computing requires scientific and technological advances in a wide variety of fields, as well as new software and system architectures that support the effective integration of the constituent technologies. This paper presents an introduction to autonomic computing, its challenges, and opportunities. 1 Introduction Advances in networking and computing technology and software tools have resulted in an explosive growth in networked applications and information services that cover all aspects of our life.

...CLOUD COMPUTING – An Overview Abstract Resource sharing in a pure plug and play model that dramatically simplifies infrastructure planning is the promise of „cloud computing‟. The two key advantages of this model are easeof-use and cost-effectiveness. Though there remain questions on aspects such as security and vendor lock-in, the benefits this model offers are many. This paper explores some of the basics of cloud computing with the aim of introducing aspects such as: Realities and risks of the model Components in the model Characteristics and Usage of the model The paper aims to provide a means of understanding the model and exploring options available for complementing your technology and infrastructure needs. An Overview Cloud computing is a computing paradigm, where a large pool of systems are connected in private or public networks, to provide dynamically scalable infrastructure for application, data and file storage. With the advent of this technology, the cost of computation, application hosting, content storage and delivery is reduced significantly. Cloud computing is a practical approach to experience direct cost benefits and it has the potential to transform a data center from a capital-intensive set up to a variable priced environment. The idea of cloud computing is based on a very fundamental principal of „reusability of IT capabilities'. The difference that cloud computing brings compared to traditional concepts of “grid computing”, “distributed computing”, “utility...

...contributions to the kernel co-scheduling. The former is we provide a model to predict the running time of merged kernel. According to experiments, our model predicts accurately in most situations. The latter is we put forward a new method in selecting kernels from pending list to be merged. Comparing to simply merging neighbor kernels, the co-scheduling method presented in this paper could utilize GPU resource more fully and improve the overall performance. 1. Introduction With the rapid advance in IC technology, and the bottleneck of performance improvement in traditional single processor architecture, CMP was proposed as significant approach to make better use of the increasing transistors. With its advantage in exploit of higher level parallelism in DLP, TLP, and less consumption compared with single processor architecture, Multicore processors has become the main stream architecture. However, the performance cannot always be improved by adding cores into a chip because of the memory bandwidth limit. The performance is especially bad for data-intensive programs like informatics applications. Moreover, the function of multicore processors is fixed whose flexibility is not enough for numerable applications. Heterogeneous multicore architecture with specialized accelerator is a more flexibility way for high performance computer. Reconfigurable computer and graphics processing unit (GPU) are considered as two promising approach in this situation. The nature of GPU, which...
