Computational physics with PetaFlops computers

Computer Physics Communications, 2009
Abstract Driven by technology, Scientific Computing is rapidly entering the PetaFlops era. The Julich Supercomputing Centre (JSC), one of three German national supercomputing centres, is focusing on the IBM Blue Gene architecture to provide computer resources of this class to its users, the majority of whom are computational physicists.

Physical computation

Concurrency: Practice and Experience, 1991
AbstractPhysical computation embraces a variety of physical analogies used to tackle non‐traditional problems. We describe Monte Carlo and deterministic methods, including simulated annealing and neural networks. Applications include economic change in Eastern Europe, the travelling salesman problem, vehicle navigation, track finding, and parallel ...

Computational physics: a perspective

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2002
Computing comprises three distinct strands: hardware, software and the ways they are used in real or imagined worlds. Its use in research is more than writing or running code. Having something significant to compute and deploying judgement in what is attempted and achieved are especially challenging. In science or engineering, one must define a central

Computations in fusion Physics

Applied Mathematics and Computation, 1986
The modern approach to nuclear fusion uses inertial confinement by a high-power laser beam, and the computer codes used to simulate the plasma behaviour now contain a lot of physics. Nonlinear interaction of a laser with a turbulent plasma is a major topic of experimental and numerical study. Simulation can be on either the particle or the hydrodynamic

Simulating physics with computers

International Journal of Theoretical Physics, 1982
This chapter describes the possibility of simulating physics in the classical approximation, a thing which is usually described by local differential equations. But the physical world is quantum mechanical, and therefore the proper problem is the simulation of quantum physics. A computer which will give the same probabilities as the quantum system does.

Physical computing in computer science education

Proceedings of the tenth annual conference on International computing education research, 2014
Physical computing covers the design and realization of interactive objects and installations and allows students to develop concrete, tangible products of the real world, which arise from the learners' imagination. This can be used in computer science education to provide students with interesting and motivating access to the different topic areas of ...

The physical basis of computability

Computing in Science & Engineering, 2002
Simulations work in practice because they exploit higher-level organizing principles in nature. Good code writing requires faithfulness to these principles and the discipline not to exceed their limits of validity. An important exception is the use of simulation to search for new kinds of emergence.

A computing architecture for physics

Proceedings of the 2nd conference on Computing frontiers, 2005
In this paper, we show how a computing architecture, called "Salt", might be able to implement the workings of a particular Discrete Space-Time-State model of Physics (DSTSP). While what is presented is certainly not a correct model of fundamental processes in physics, it illustrates how such models could give us insights into new methods of modeling ...

Physical computing for everyone

2017 IEEE/ACM 39th International Conference on Software Engineering: Software Engineering Education and Training Track (ICSE-SEET), 2017
Thanks to Moore's Law, embeddable microcontroller-based devices continue to get cheaper, faster, and include more integrated sensors and networking options. In 2016, the BBC and a host of technical partners, including Microsoft, delivered such a physical computing device, the micro:bit, to every 5th grader in the UK.

Physics of computing as an introduction to computer engineering

2013 IEEE Frontiers in Education Conference (FIE), 2013
This paper describes a new required course in the Georgia Tech computer engineering curriculum, ECE 3030, Physical Foundations of Computer Systems. Traditional introductory courses take a constructive approach to logic design and computer organization. 3030, in contrast, introduces the major physical concepts underlying computation.
