Title: Evaluating unikernels for HPC applications

Abstract: Unikernels are lightweight single-application operating systems. They are designed to run as virtual machines, but some are able to run on bare metal too. They are quite popular in the system research community due to the increase of performance they can provide. By reducing the system call overhead and the OS-noise, they might be a good alternative to containers for HPC applications. This report evaluate the suitability of unikernels for HPC applications. This is done by conducting stability and performance studies with the Bots benchmarks and the Rodinias benchmarks. They are performed on multi-core architectures, on single node.

Title: Optimization of software license placement in the Cloud for economical and efficient deployment

Abstract: Today, the use of software is generally regulated by licenses, whether they are free, paid for and with or without access to their sources. The world of licensing is very vast and poorly understood. Often we only know the version most widely used by the general public (a software purchase is equal to a license). The reality is much more complex, especially for large publishers. In this presentation I will present the impact and importance of managing these licenses when using software in a cloud architecture. I will show a case study to demonstrate the impact of dynamic license management and the need to propose new ways to manage and optimize software assets.

Titre: Optimisation du placement des licences logicielles dans le Cloud pour un déploiement économique et efficient

Résumé: Aujourd’hui, l’utilisation des logiciels est généralement réglementée par des licences, qu’elles soient gratuites, payantes et avec ou sans accès à leurs sources. L’univers des licences est très vaste et mal connu. Souvent on ne connaît que la version la plus répandue au grand public (un achat de logiciel est égale à une licence). La réalité est bien plus complexe surtout chez les grands éditeurs. Dans cette présentation je présenterai l’impact et l’importance de la gestion de ces licences lors de l’utilisation de logiciels dans une architecture Cloud. Je montrerai un cas d’étude pour prouver l’impact de la gestion dynamique des licences et la nécessité de proposer de nouvelles façons de gérer et optimiser un patrimoine logiciel.
