چکیده

With the increasing numbers of Cloud Service Providers and the migration of the Grids to the Cloud paradigm, it is necessary to be able to leverage these new resources. Moreover, a large class of High Performance Computing (hpc) applications can run these resources without (or with minor) modifications. But using these resources come with the cost of being able to interact with these new resource providers. In this paper we introduce the design of a hpc middleware that is able to use resources coming from an environment that compose of multiple Clouds as well as classical hpc resources. Using the Diet middleware, we are able to deploy a large-scale, distributed hpc platform that spans across a large pool of resources aggregated from different providers. Furthermore, we hide to the end users the difficulty and complexity of selecting and using these new resources even when new Cloud Service Providers are added to the pool. Finally, we validate the architecture concept through cosmological simulation ramses. Thus we give a comparison of 2 well-known Cloud Computing Software: OpenStack and OpenNebula.

Dans ce papier, nous introduisons la conception d’un nouveau intergiciel hpc qui permet d’utiliser les ressources qui proviennent d’un environement compos de plusieurs Clouds comme des ressources classiques. En utilisant l’intergiciel Diet, nous sommes capable de dployer une plateforme hpc distribue et large chelle qui s’tend sur un large ensemble de ressources aggrges entre plusieurs fournisseurs Cloud.

Automatic memory-based vertical elasticity and oversubscription on cloud platforms

Hypervisors and Operating Systems support vertical elasticity techniques such as memory ballooning to dynamically assign the memory of Virtual Machines (VMs). However, current Cloud Management Platforms (CMPs), such as OpenNebula or OpenStack, do not currently support dynamic vertical elasticity. This paper describes a system that integrates with the CMP to provide automatic vertical elasticity...
