Qarnot computing heats buildings with computations. Qarnot Render is a fully-featured renderfarm supporting many applications (V-Ray, Blender, Renderman, Guerilla...), accessible through a super-friendly web interface, a REST API and/or a Python SDK. A distributed cloud made up of computing heaters and boilers using high-end CPUs to heat offices and residential buildings, Qarnot Render is as eco-friendly as performant. "Cosmos Laundromat", short movie by the Blender foundation and Jury Prize award at SIGGRAPH 2016, was entirely rendered with Qarnot.
