The Italian GPS receiver for Radio Occultation has been launched from the Satish Dhawan Space Center (Sriharikota, India) on board of the Indian Remote Sensing OCEANSAT-2 satellite. The Italian Space Agency has established a set of Italian universities and research centers to develop an innovative solution in order to quickly elaborate RO data and extract atmospherical profiles. The algorithms adopted can be used to characterize the temperature, pressure and humidity. In consideration of large amount of data to process, an hybrid infrastructure has been created using both the existing grid environment (fully physical) and the virtual environment composed of virtual machines from local cloud infrastructure and Amazon EC2. This enhancement of the project stems from the need of computational power in case of an unexpected burst of calculation that the physical infrastructure would not be able to respond on its own. The virtual environment implemented guarantees flexibility and a progressive scalability and other benefits derived by virtualization and cloud computing. © 2013 Springer-Verlag Berlin Heidelberg.

TopHat is a fast splice junction mapper for Next Generation Sequencing analysis, a technology for functional genomic research. Next Generation Sequencing technology allows more accurate analysis increasing data to elaborate, this opens to new challenges in terms of development of tools and computational infrastructures. We present a solution that cover aspects both software and hardware, the first one, after a reverse engineering phase, provides an improvement of algorithm of TopHat making it parallelizable, the second aspect is an implementation of an hybrid infrastructure: grid and virtual grid computing. Moreover the system allows to have a multi sample environment and is able to process automatically totally transparent to user. © 2012 IEEE. Source
