Java is a very commonly used computer programming language, although its use amongst the scientific and High Performance Computing (HPC) communities remains relatively low. In this thesis, we investigate the use of Java for scientific applications in HPC environments, taking into account modern Java Virtual Machines (JVMs), the tools and libraries available(More)
The Large Observatory For x-ray Timing (LOFT) was studied within ESA M3 Cosmic Vision framework and participated in the final downselection for a launch slot in 2022-2024. Thanks to the unprecedented combination of effective area and spectral resolution of its main instrument, LOFT will study the behaviour of matter under extreme conditions, such as the(More)
The Large Observatory For x-ray Timing (LOFT) is a mission concept which was proposed to ESA as M3 and M4 candidate in the framework of the Cosmic Vision 2015-2025 program. Thanks to the unprecedented combination of effective area and spectral resolution of its main instrument and the uniquely large field of view of its wide field monitor, LOFT will be able(More)
The scientific instruments included in modern space missions require high compression ratios in order to downlink all the acquired data to the ground. In many cases, this must be achieved without losses and the available processing power is modest. Algorithms requiring large amounts of data for their optimum operation cannot be used due to the limited(More)
