It is the world’s No. 1 system with a performance of 33.86 petaflop/s on the Linpack benchmark. Used for government analysis and security applications, each of its 16,000 nodes possess 88 gigabytes of memory (64 used by the Ivy Bridge processors, and 8 gigabytes for each of the Xeon Phi processors). Researchers have criticized Tianhe-2 for being difficult to use, claiming: "It is at the world's frontier in terms of calculation capacity, but the function of the supercomputer is still way behind”. Titan Titan is an upgrade of Jaguar, a previous supercomputer at Oak Ridge National Laboratory, which uses graphics processing units (GPUs) in addition to conventional central processing units (CPUs). Titan is the first such hybrid to perform over 10 petaFLOPS. The upgrade began in October 2011, commenced stability testing in October 2012 and it became available to researchers in early 2013. The initial cost of the upgrade was US$60 million, funded primarily by the United States Department of Energy. Titan will itself be replaced by an approximately 200 petaFLOPS system in the near future. Sequoia Sequoia, at Lawrence Livermore National Laboratory in California, is the most powerful machine that does not use GPU-type accelerators alongside its main processor cores. Record-breaking science applications have been run on Sequoia, including a cosmology simulation framework HACC, which achieved almost 14 petaflops with a 3.6 trillion particle benchmark run. Sequoia will be used primarily for nuclear weapons simulation. It will also be available for scientific purposes such as astronomy, energy, lattice QCD, study of the human genome, and climate change. K Computer Fujitsu’s K Computer operates at Japan’s Advanced Institute for Computational Science, running simulations for weather forecasting, pharmacological research, space science and more. The K computer is based on a distributed memory architecture with over 80,000 computer nodes. It is used for a variety of applications, including climate research, disaster prevention and medical research. The K computer uses a proprietary six-dimensional torus interconnect called Tofu, and a Tofu-optimized Message Passing Interface based on the open-source Open MPI library. Mira Mira has a performance of 8.59 petaflops (LINPACK) and consumes 3.9 MW. It was constructed by IBM for Argonne National Laboratory's Argonne Leadership Computing Facility. The Argonne Leadership Computing Facility, which commissioned the supercomputer, was established by the America COMPETES Act, signed by President Bush in 2007, and President Obama in 2011. Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited super lubricity at the macroscale.
