CarbonQuant software developed by EPI Tosca aims at pricing carbon dioxyd gas discharge for the european market. The carbon market was launched in the European Union in 2005 as part of the EU’s initiative to reduce its greenhouse gas (GHG) emissions. For industrial actors, this means that they now have to include their GHG emissions in their production costs. CarbonQuant aims at modeling the behavior of an industrial agent who faces uncertainties, and it compares the expected value of optimal production strategy when buying (or not buying) supplementary emission allowances. This allows us to compute the agent’s carbon indifference price. The resulting indifference price is used to study carbon market sensitivity with respect to the shape of the penalty and the emission allowances allocation.

DEDALE-HF is software developed by the Apics research team, permitting the synthesis of equivalent circuits for hyperfrequency filters by solving the problem of electromagnetic coupling matrix synthesis. For a given type of filters, DEDALE-HF makes it possible to find all of the possible electromagnetic coupling values leading to the production of this filter's characteristics. The resolution of this problem is crucial during the development and optimisation of a hyperfrequency filter.

FindSource3D (FS3D++)

FS3D++ is a platform developed by EPI Apics, Athena and by the CMA of Mines-Paritech. It is dedicated to the resolution of inverse source problems in electroencephalogrphy (EEG). From pointwise measurements of the electric potential, numerically obtained or taken by electrodes on the scalp, FS3D++ estimates pointwise dipolar current sources within the brain.


Jean-Antoine Désidéri is launching the MGDA (Multiple Gradient Descent Algorithm) Platform for multi-objective differentiable optimization.
The software will permit you to compute a descent descent common to an (almost) arbitrary family of criteria for which the gradients at a given design-point are provided.
The platform can be used in two different modes:

  • the interactive mode, via a web interface that facilitates the exchange of data between the user and a machine at Inria dedicated to the computation
  • the iterative mode, for which the user downloads the object library (under a free license for usage within an academic environment) to be included in a private optimization program.

The platform num3sis developed by EP Acumes (former Opale) and Nachos is devoted to scientific computing and numerical simulation. It is not restricted to a particular application field, but is designed to host complex multidisciplinary simulations. Main application fields are currently Computational Fluid Dynamics (CFD), Computational Structural Mechanics (CSM), Computational Electro-Magnetics (CEM). Nevertheless, num3sis can be a framework for the development of other numerical simulation tools for new application areas, such as pedestrian traffic modeling for instance.

PRESTO-HF is a toolbox dedicated to the identification of low-pass hyperfrequency filter parameters developed within the Apics research team. It makes it possible to recover the coupling parameters of a low-pass electrical circuit equivalent to the studied filter. PRESTO-HF is therefore involved in adjustment processes making it possible to reduce the hardware cost and optimise computer-aided design (CAD).

TAPENADE is an automatic differentiation engine developed within the Ecuador research team. It makes it possible to obtain the exact derivatives of a function represented by a computer program in order to optimise the performance of this program. TAPENADE operates through program transformation and generates, from the function's code, a new code that computes the derivatives and will need to be executed. The benefit of this model is that the code computing the derivative can be reused in another code, such as an optimiser, for example. TAPENADE is distributed free of charge for academic use and under a paid proprietary licence for industrial use. It is becoming the most used automatic differentiation software in the world.

HOP is a software development kit for Web 2.0 developed by the Indes research team. It permits the programming of varied interactive Web applications: multimedia (photo gallery, music player, etc.), office automation (calendars, e-mail client, etc.), or home automation, for example by optimising use of existing Web tools. The applications thus developed can then be used on numerous architectures (computer, PDA, mobile telephone) and operating systems (Linux, MacOS, Maemo, Windows). Thanks to HOP, the Web is seen as a portable, universal virtual machine. HOP is distributed under an open-source GPL licence.

It can be used for the programming and execution of parallel applications on Linux, Windows and MacOS as well as the management of resources (stations, servers, clusters, grid or cloud). This technology was patented by Inria and Université de Nice-Sophia Antipolis in 2004. The patent and software were the subject of exclusive operating licensing to the start-up ACTIVEEON in 2008. At the same time, ProActive Parallel Suite is distributed under an open-source GPL licence, and collaborative research projects implementing this software are underway with academic and industrial partners.

ODIN is a platform developed by the Biocore research team in order to supervise and optimise bioreactors (controllers, observers, diagnostics). It is the subject of a technology development action to optimise the platform in order to be able to be used within an industrial setting, far from any computing expertise. Although exclusively developed within Inria, ODIN is the subject of a strong collaboration with the Laboratory of Environmental Biotechnologies of INRA-Sarbonne and the Villefranche Oceanography Laboratory (CNRS-Paris 6). In general, ODIN is involved in biotechnology developments mobilising instrumented bioreactors, thus leaving a very broad field of applications. It can therefore be used at the research level as well as at the industrial level for which there are no comparable products, since it involves implementing complex algorithms.


EnaS developed by Biovision enables analysis of neural population in large scale spiking networks. With the advent of new Multi-Electrode Arrays techniques (MEA), the simultaneous recording of the activity up to hundreds of neurons over a dense configuration supplies today a critical database to unravel the role of specific neural assemblies. Thus, the analysis of spike trains obtained from in vivo or in vitro experimental data requires suitable statistical models and computational tools. The EnaS software offers new computational methods of spike train statistics. It also features several statistical model choices and allows a quantitative comparison between them. Eventually, it provides a control of finite-size sampling effects inherent to empirical statistics.


In@lgae is developed by EPI Biocore. Its objective is to simulate the productivity of a microalgae production system, taking into account both the process type and its location and time of the year. A first module (Freshkiss) developed by Ange computes the hydrodynamics, and reconstructs the Lagrangian trajectories perceived by the cells. Coupled with the Han model, it results in the computation of an overall photosynthesis yield. A second module is coupled with a GIS (geographic information system) to take into account the meteorology of the considered area (any location on earth). The evolution of the temperature in the culture medium together with the solar flux is then computed. Finally, the productivity in terms of biomass, lipids, pigments together with CO2, nutriments, water consumption, … are assessed. The productivity map which is produced can then be coupled with a resource map describing the availability in CO2 nutrients and land.

Biological Image Platform (PIB) 

The PIB platform developed by EPI Morpheme provides visual programming framework for the definition of workflows that enable to characterize and model the development and the morphological properties of biological structures from the cell to the supra-cellular scale.
