A major challenge in modelling and simulation is the need to combine expertise in both
software technologies and a given scientific domain. When High-Performance Computing …

Due to energy crisis of the last years, energy waste and sustainability have been brought
both into public attention, and under industry and scientific scrutiny. Thus, obtaining high …

As society's dependence on Information and Communication Technologies (ICTs) grows,
providing efficient and resourceful services entails many complexities that require, among …

Many current applications provide high performance to process large volumes of data.
These applications usually run in highly distributed environments, like cloud and HPC …

For each kind of distributed computing infrastructures, ie, clusters, grids, clouds, data
centers, or supercomputers, storage is a essential component to cope with the tremendous …

In this paper, we present an approach with the goal to improve the underlying architecture of
cloud systems. For this, we propose UML2Cloud, a framework targeted at modeling and …

State-of-the-art cloud simulators in use today are limited in the number of features they
provide, lack real network communication models, and do not provide extensive Graphical …

The generation of test data for state-based specifications is a computationally expensive
process. This problem is magnified if we consider that time constraints have to be taken into …

Cloud computing is a paradigm that provides access to a flexible, elastic and on-demand
computing infrastructure, allowing users to dynamically request virtual resources. However …
