Abstract:Recently, many educational institutions have had to maintain a large number of PCs (educational PCs). It is common for the administrators of these institutions to use a disk image distribution system to manage them all together. It allows the administrators to keep all of their educational PCs in the same configuration with ease. This method, however, robs them of the flexibility of management. Suppose that use of certain application software is restricted to specific users or sites in those institutions. Suppose also that use of other application software is requested to be prohibited by teachers during classes. It is hard for the administrators to satisfy all of these requirements with the traditional method since it causes heavy administrative burden. This paper proposes a flexible method to manage application software on educational Windows PCs without significant efforts of the administrators even with these requirements. The proposed method controls the execution of individual application software on each educational PC to create the requested environments. Teachers as well as the administrators can directly and dynamically change its configuration during their classes. An execution control system was actually implemented as a prototype to show the feasibility of the proposed method.

“…For this reason, recent advances in distributed computing under the rubrics of grid computing and cloud computing [1] promise significant gains in resource usage efficiency and staff productivity. Scientific and educational computing are two important settings where the above-mentioned advances can apply [2]. For example, research groups in different institutions can contribute their otherwise unused resources to a common pool with the understanding that they would benefit from the common pool when they need additional resources.…”

“…To develop the above ideas further, consider a simple, but real, example of a federated computing environment. Some North Carolina institutions-including NC State University (NCSU: our institution) and NC Central University (NCCU)-federate some of their computing resources through the Virtual Computing Lab (VCL), an open source cloud infrastructure [7], [2], [8]. Their motivation is that they need to provide their respective users (students and faculty) virtual access to hosted applications such as Matlab, and federating resources enables handling peak loads better.…”

Licit: Administering Usage Licenses in Federated Environments

Abstract-We address the problem of usage license administration in federated settings. This problem arises whenever organizations, such as educational or research groups or institutions, share resources for business and scientific reasons. In such settings, each user's usage of a licensed resource is typically supported by the user's organization. License administration involves satisfying legal requirements while applying organizational strategies for effective resource usage, and carrying out suitable accounting and audit controls. We propose an approach, Licit, wherein an agent represents each resource sharing site and administers licenses in collaboration with other agents. We show how to represent a variety of usage licenses formally as executable policies and provide a simple information model using which each party can specify both the attributes involved in its licenses and how to resolve them. Our architecture naturally accommodates a variety of site-specific (i.e., custom) strategies for license administration. Licit has been implemented in a popular open source framework for virtual computing, and yields performance results indicating its practical feasibility.

“…There is previous work such as NCSU VCL model in which the goal is partially achieved with some unresolved issues [3,6]. VDI is good for remote access for limited users who got ids of the service, but it is bounded by the capacity of host server machines on a cloud computing.…”
