A GRID-BASED E-LEARNING MODEL FOR OPEN UNIVERSITIES
E-learning has grown to become a widely
accepted method of learning all over the world. As a
result, many e-learning platforms which have been
developed based on varying technologies were faced
with some limitations ranging from storage
capability, computing power, to availability or access
to the learning support infrastructures. This has
brought about the need to develop ways to
effectively manage and share the limited resources
available in the e-learning platform. Grid computing
technology has the capability to enhance the quality
of pedagogy on the e-learning platform.
In this paper we propose a Grid-based e-learning
model for Open Universities. An attribute of such
universities is the setting up of multiple remotely
located campuses within a country.
The grid-based e-learning model presented in
this work possesses the attributes of an elegant
architectural framework that will facilitate efficient
use of available e-learning resources and cost
reduction, leading to general improvement of the
overall quality of the operations of open universities
A Pedagogy for Original Synners
Part of the Volume on Digital Young, Innovation, and the UnexpectedThis essay begins by speculating about the learning environment of the class of 2020. It takes place entirely in a virtual world, populated by simulated avatars, managed through the pedagogy of gaming. Based on this projected version of a future-now-in-formation, the authors consider the implications of the current paradigm shift that is happening at the edges of institutions of higher education. From the development of programs in multimedia literacy to the focus on the creation of hybrid learning spaces (that combine the use of virtual worlds, social networking applications, and classroom activities), the scene of learning as well as the subjects of education are changing. The figure of the Original Synner is a projection of the student-of-the-future whose foundational literacy is grounded in their ability to synthesize information from multiple information streams

The Climate Imperative and Innovative Behavior: Encouraging Greater Advances in the Production of Energy-Efficient Technologies and Services
This white paper examines why a larger array of innovative institutions, behaviors, technologies, and servicesis needed â specifically in the context of what we call âthe climate imperative.â We explore possible mechanisms that can encourage the more robust development of innovative programs and policies within the State of California, with special attention to the activities of the California Public Utilities Commission
The OMII Software â Demonstrations and Comparisons between two different deployments for Client-Server Distributed Systems
This paper describes the key elements of the OMII software and the scenarios which OMII software can be deployed to achieve distributed computing in the UK e-Science Community, where two different deployments for Client-Server distributed systems are demonstrated. Scenarios and experiments for each deployment have been described, with its advantages and disadvantages compared and analyzed. We conclude that our first deployment is more relevant for system administrators or developers, and the second deployment is more suitable for usersâ perspective which they can send and check job status for hundred job submissions
HPC Cloud for Scientific and Business Applications: Taxonomy, Vision, and Research Challenges
High Performance Computing (HPC) clouds are becoming an alternative to
on-premise clusters for executing scientific applications and business
analytics services. Most research efforts in HPC cloud aim to understand the
cost-benefit of moving resource-intensive applications from on-premise
environments to public cloud platforms. Industry trends show hybrid
environments are the natural path to get the best of the on-premise and cloud
resources---steady (and sensitive) workloads can run on on-premise resources
and peak demand can leverage remote resources in a pay-as-you-go manner.
Nevertheless, there are plenty of questions to be answered in HPC cloud, which
range from how to extract the best performance of an unknown underlying
platform to what services are essential to make its usage easier. Moreover, the
discussion on the right pricing and contractual models to fit small and large
users is relevant for the sustainability of HPC clouds. This paper brings a
survey and taxonomy of efforts in HPC cloud and a vision on what we believe is
ahead of us, including a set of research challenges that, once tackled, can
help advance businesses and scientific discoveries. This becomes particularly
relevant due to the fast increasing wave of new HPC applications coming from
big data and artificial intelligence.Comment: 29 pages, 5 figures, Published in ACM Computing Surveys (CSUR
