Virtualization overhead is the main reason for the slow diffusion of virtualization techniques into high-performance computing environments. This paper discusses the issues linked to the performance evaluation of virtual clusters, and presents the implementation of a service that automates the benchmarking and results collection procedure in an existing cloud-on-GRID environment.
The advancement in computer technologies and the transference of these technologies to simulators for medical education continues to be a driving force in medical education. The complexities of surgical training and the emergence of minimally invasive surgery (MIS) as a primary surgical mode have pushed the surgical simulator to the forefront of surgical education. Simulators are now developed by...
The CoMetS workshop aims to bring together leading researchers and practitioners from both the modeling and simulation (M&S) community and the collaborative environments community, in order to focus on innovative research contributions that address both the use of collaborative technologies in the field of M&S and the use of M&S methodologies and tools to address the design of collaborative...
The following topics are dealt with: collaborative enterprises; agent-based computing; cloud computing; cooperative knowledge discovery; data mining; and collaborative peer-to-peer systems.
In this paper we present an hybrid architecture for a computer supported collaborative work in pervasive computing environment simulator. This architecture supports pure simulation mode where all agents are simulated, real deployment where it seamlessly integrates pervasive computing to the computer supported collaborative work and finally an hybrid mode where real devices can interact with simulated...
In this paper a review of the possible applications of Information and Communications Technologies (ICT) to the renewable energy sector is presented. Renewable energies are provided by natural resources (sunlight, wind, water, and geothermal heat) through the use of engineering technologies able to collect the energy and to convert it in a more usable form. ICT can play a significant role in this...
Resource discovery mechanisms are key for distributed computing. Traditional approaches use dedicated servers to store information about the whole system and make all the scheduling decisions. Many mechanisms exist for decentralized environments, based on distributing the information in a certain way over a structured overlay network. This usually creates complex relationships between the distribution...
We present here a brief summary of the works presented this year to the COPS 2010 workshop. The COPS workshop is in its sixth edition and it attracts top researchers from the peer-to-peer field. This year the workshop had an acceptance rate of 40% with 6 full papers accepted from a total of 15 submissions.
The volumetric growth of data complexity is increasing day by day. The computational world is becoming massive and needs scalable and efficient systems. Data management is an important stage to accelerate the petabytes processing. Such environment requires scientific work flows to compose and manage those volumetric data sets. Scientific Workflow is different than general workflow. It deals with scheduling,...
Requirements management and prioritization is a complex process that should take into account requirements value for customers, cost of implementation, available resources, requirements interdependencies, system architecture and dependencies to the code base. In this paper we present how Social Network Analysis can be used in order to improve software requirements management and the prioritization...
Cloud Computing is becoming one of the most important topics in the IT world. Several challenges are being raised from the adoption of this computational paradigm including security, privacy, and federation. This paper aims to introduce new concepts in cloud computing and security, focusing on heterogeneous and federated scenarios. We present a reference architecture able to address the Identity Management...
Grid system is a promising solution for sharing distributed resources of registered participants to perform tasks whose demands may exceed the capacity of individual participating organization. However, the collaborative aspect of Grids is still underdeveloped as they lack features and mechanisms for human interaction and collaboration. This paper presents the design and development of a prototype...
External shocks, negative conjuncture, periods of crisis are known to often constitute turning points for enterprises. On the one hand, managers urge to revise their business model, in order to adapt it to the changes of the external environment and of the competitive scenario. On the other hand, exogenous shocks usually affect collaboration with other players on the market. Such strategies as outsourcing,...
