You dont see many supercomputers runing Windows these days though - not because of any scalability limitation - it certainly scales and tends to beat say Linux with say wide band low latency performance such as Mellanox interconnects or 100GBe networking. The main reason is because it's licenced per core, and top end supercomputers can have more than 10 million cores!
