Several news sites have reported that the world has a new fastest super computer, capable of performing 200,000 trillion calculations per second (200 petaflops). The new super computer, named Summit, was built by IBM and uses a combination of Power9 processors and NVIDIA graphics cards. The computer's operating system: Red Hat Enterprise Linux. Network World reports: "If you knew that the top ten fastest supercomputers in the world today all run a variant of Linux, Red Hat's role in Summit might not be such a surprise. But don't stop there. The benefit to users of having a familiar OS (many national labs and research centers run Red Hat Enterprise Linux on their systems) makes Summit approachable in a way that older supercomputers have generally not been. The requirements for flexibility and scalability required for IT operations are considerably more important when it comes to supercomputing with its highly specialized components. Red Hat Enterprise Linux provides stability, support, and its open nature."
