    Lattice quantum chromodynamics (QCD) calculations were one of the first applications to demonstrate the potential of GPUs in the area of high-performance computing; the nature of lattice QCD calculations matches well with the GPU's computational model. This article discusses ways to effectively use GPUs for lattice calculations using the overlap operator, a discretization that preserves chiral sym... View full abstract»

    Subatomic particles known as hadrons, such as protons and neutrons, are composite objects comprised of elementary particles called quarks that interact via the exchange of massless gluons. The dynamics of quarks and gluons inside hadrons are described by a theory known as quantum chromodynamics. To date, the best approach to calculating hadron properties is to formulate this theory on a space-time... View full abstract»

    Simulations of the entire universe are by definition models of the largest and most complex physical system that exists. In carrying them out, simulators seek to discretize the matter (and radiation) in a model universe and follow their evolution from the Big Bang to the present day. View full abstract»

    The next generation of supercomputers will likely consist of a hierarchy of parallel computers. If we define each supercomputer node as a parameterized abstract machine, then it's possible to design algorithms independently of the hardware. Such an abstract machine can be defined to consist of a collection of vector (SIMD) processors, each with a small fast memory communicating via a larger global... View full abstract»

    For extreme-scale high-performance computing systems, system-wide power consumption has been identified as one of the key constraints moving forward, where DRAM main memory systems account for about 30 to 50 percent of a node's overall power consumption. As the benefits of device scaling for DRAM memory slow, it will become increasingly difficult to keep memory capacities balanced with increasing ... View full abstract»
