Ecological transition: a central concern of CBPsmn activities and research

Emmanuel Quémener, from CBPsmn, presents his immersion cooling project. When research and transition progress in tandem. Emmanuel Quémener, research engineer at the Centre Blaise Pascal de Simulation et Modélisation Numérique (CBPsmn - Blaise Pascal Centre  for Simulation and Numerical Modeling) at ENS de Lyon, opens the doors of his computer rooms to us. This "computer test pilot" is particularly sensitive to ecological transition issues, which influence his approach to project management. As illustrated by his work on cooling immersion. To find out how research and transition progress in tandem, follow us! When managing a fleet of hundreds of machines, a good way of thinking about the ecological transition is to think in terms of carbon costs. Plural, because there are three of them: production and acquisition, provision and operation, and disposal. To recover manufacturing costs, extend the operating time and recycle equipment. The calculation sounds easy.. but it isn't! Not all machine components age in the same way. So, to scrap (or even recycle) all the components of the same piece of equipment is to throw away components that can be used for many years to come. This is where Emmanuel Quémener comes in. First stop: the machine learning room. This new collaborative room was set up with the help of the region, which financed the screens. The screens, which are difficult to transform and evolve, are the room's highest carbon cost devices. As for the rest, it's all about reuse. Under their hoods, the machines are made from computers deemed obsolete: cases, processors, memory sticks, hard disks. All working components are recovered and then recombined, with the only new component being an additional graphics card. The aim?
