A Unified Monitoring Framework for Energy Consumption and Network Traffic

International audienceProviding experimenters with deep insight about the effects of theirexperiments is a central feature of testbeds. In this paper, wedescribe Kwapi, a framework designed in the context of the Grid'5000testbed, that unifies measurements for both energy consumption andnetwork traffic. Because all measurements are taken at theinfrastructure level (using sensors in power and network equipment),using this framework has no dependencies on the experiments themselves.Initially designed for OpenStack infrastructures, the Kwapi framework allowsmonitoring and reporting of energy consumption of distributed platforms. Inthis article, we present the extension of Kwapi to network monitoring, andoutline how we overcame several challenges: scaling to a testbed the size ofGrid'5000 while still providing high-frequency measurements; providing long-termloss-less storage of measurements; handling operational issues when deployingsuch a tool on a real infrastructure

The transposable element-rich genome of the cereal pest Sitophilus oryzae

Background The rice weevil Sitophilus oryzae is one of the most important agricultural pests, causing extensive damage to cereal in fields and to stored grains. S. oryzae has an intracellular symbiotic relationship (endosymbiosis) with the Gram-negative bacterium Sodalis pierantonius and is a valuable model to decipher host-symbiont molecular interactions. Results We sequenced the Sitophilus oryzae genome using a combination of short and long reads to produce the best assembly for a Curculionidae species to date. We show that S. oryzae has undergone successive bursts of transposable element (TE) amplification, representing 72% of the genome. In addition, we show that many TE families are transcriptionally active, and changes in their expression are associated with insect endosymbiotic state. S. oryzae has undergone a high gene expansion rate, when compared to other beetles. Reconstruction of host-symbiont metabolic networks revealed that, despite its recent association with cereal weevils (30 kyear), S. pierantonius relies on the host for several amino acids and nucleotides to survive and to produce vitamins and essential amino acids required for insect development and cuticle biosynthesis. Conclusions Here we present the genome of an agricultural pest beetle, which may act as a foundation for pest control. In addition, S. oryzae may be a useful model for endosymbiosis, and studying TE evolution and regulation, along with the impact of TEs on eukaryotic genomes.Funding for this project was provided by the Fondation de l’Institut National des Sciences Appliquées-Lyon (INSA-Lyon), the research direction of INSA-Lyon, the Santé des Plantes et Environnement (SPE) department at the Institut National de Recherche pour l'Agriculture, l'Alimentation et l'Environnement (INRAE), the French ANR-10-BLAN-1701 (ImmunSymbArt), the French ANR-13-BSV7-0016-01 (IMetSym), the French ANR-17_CE20_0031_01 (GREEN), and a grant from la Région Rhône-Alpes (France) to AH.

Generic Hardware Description for Embedded Platforms

On the area of microcontrollers, a firmware is traditionally built for a very specific hardware configuration. Without special design, there is little chance that the same firmware will run on several hardware platforms with a different sets of peripherals. But running the same firmware on different hardware configurations could have some benefits. It could allow a manufacturer or a sensor network manager to deploy the exact same firmware on all its nodes regardless of their hardware. It would greatly simplify the firmware management, and thus the update process. We know that such a system is possible on larger architectures, such as x86 or even ARM, but in this thesis we target smaller architectures. The typical target here is a sensor network node, running on a very low-power microcontroller. No generic system currently exists to allow a firmware to run on several hardware configurations of this type. In this thesis we present a new generic hardware description system that specifically targets small devices. This system can be integrated with existing frameworks or operating systems for embedded systems so that the firmware can adapt to the hardware it is running on. We show that it is possible by presenting a demonstration prototype using our hardware description system
