Qarnot rethinks data centers by breaking up collections of servers and spreading them into buildings (homes, offices, schools...) in the form of computing heaters and boilers embedding high performance processors. We also operate computing clusters in warehouses. The waste heat is reused instantly thanks to our disruptive platform that dispatches automatically the computation where heat (of air or water) is needed. By avoiding data center costs related to infrastructure, maintenance, and cooling, Qarnot offers affordable HPC.
