Un double constat motive ce travail: la demande en calcul haute performance des chercheurs et la faible utilisation moyenne de la puissance des ressources pédagogiques. Le problème a été de répondre à cette demande, tout en préservant les ressources pédagogiques pour les enseignements. Une solution simple et transparente pour les utilisateurs finaux a été recherchée. Les besoins des utilisateurs ont mené à un cahier des charges dont la plupart des contraintes sont satisfaites par l'utilisation d'une pile logicielle judicieuse. D'autres ne peuvent être résolues par la seule utilisation de solutions existantes et définissent un problème d'ordonnancement, où il faut répartir les processus soumis sur les ressources des salles de TPs. Plusieurs heuristiques ont été proposées pour le résoudre. Elles ont été comparées à l'aide d'un simulateur, puis implémentée sur une plateforme expérimentale. / Two facts are motivating this work: the demand for High Performance Computing of researchers and the low usage of the computing power of the pedagogic ressources. This thesis aims at giving an answer to the demand for HPC, while preserving the pedagogic ressources for the teaching. This work looked for a solution that would be simple and straightforward for the final users. Their needs and wishes lead to the definition of some specifications, in which most of the constraints could be satisfied with the use of a well designed software stack. Some others, however, cannot be satisfied with the use of existing solutions only, they define a new scheduling problem, in which the goal is to schedule the processes on the available ressources. This problem was studied and solved with various heurisitcs, which performances were compared with a simulator before being implemented in an experimental setup.

Charge detection is essential for a large number of commercial and scientific applications. A charge amplifier is one of the most fundamental building blocks for a detector system. This thesis describes the design, circuit implementation, and post-silicon testing of two different charge amplifier designs, analog and digital, that address some commonly seen fundamental challenges in the charge detection application. In particular, the proposed designs can be integrated with an image charge detector (ICD) to study the characteristics of dust on Mars. The proposed charge amplifier design utilizes a small 10 fF feedback capacitor to achieve a high gain. The fully integrated custom differential charge amplifier design improves the accuracy and robustness of its charge gain, and provides a compact method to extract detector capacitance for gain calibration. Conventional charge amplifiers' charge-to-voltage gain is a function of the detector parasitic capacitance. Therefore, a high precision photo-current calibration method is proposed here to enable an accurate gain calibration. In addition, a novel "digital amplifier" with close to rail-to-rail output swing is proposed to realize an infinite equivalent open-loop gain. Consisting of an ADC and charge pump as the amplifier core, this proposed design maintains a consistent closed-loop gain independent of the input parasitic capacitance. The ADC is realized as a single comparator, i.e. a 1-bit ADC, which, together with an SR latch and a differential charge pump, replaces the conventional analog amplifier core.
