Teraflop Computing for Nanoscience
Over the last three decades there has been significant progress in the first principles methods for calculating the properties of materials at the quantum level. They have largely been based on the local density approximation (LDA) to density functional theory (DFT). However, nanoscience places new demands on these first principles methods because of the thousands to millions of atoms present i...
متن کاملA Two Teraflop Swarm
We introduce the Xpuck swarm, a research platform with an aggregate raw processing power in excess of two teraflops. The swarm uses 16 e-puck robots augmented with custom hardware that uses the substantial CPU and GPU processing power available from modern mobile system-on-chip devices. The augmented robots, called Xpucks, have at least an order of magnitude greater performance than previous sw...

متن کاملHierarchical hybrid grids: achieving TERAFLOP performance on large scale finite element simulations
The design of the Hierarchical Hybrid Grids framework is motivated by the desire to achieve high performance on large-scale, parallel, finite element simulations on super computers. In order to realize this goal, careful analysis of the low-level, computationally intensive algorithms used in implementing the library is necessary. This analysis is primarily concerned with identifying and removin...
متن کاملQuantum Computing by Simulations
Quantum computing by simulations is based upon similarity between mathematical formalism of quantum mechanics and phenomena to be computed. It exploits a dynamical convergence of several competing phenomena to an attractor which can represent an extrenum of a function, an image, a solution to a system of ODE, or a stochastic process. In this chapter, a quantum version of recurrent nets (QRN) as...
