LARGESCALE SIMULATION OF BEAM DYNAMICS IN HIGH INTENSITY ION LINACS USING PARALLEL SUPERCOMPUTERS
Abstract
In this paper we present results of using parallel supercomputers to simulate beam dynamics in nextgeneration high intensity ion linacs. Our approach uses a threedimensional space charge calculation with six types of boundary conditions. The simulations use a hybrid approach involving transfer maps to treat externally applied fields (including rf cavities) and parallel particleincell techniques to treat the spacecharge fields. The largescale simulation results presented here represent a three order of magnitude improvement in simulation capability, in terms of problem size and speed of execution, compared with typical twodimensional serial simulations. Specific examples will be presented, including simulation of the spallation neutron source (SNS) linac and the Low Energy Demonstrator Accelerator (LEDA) beam halo experiment.

Extensive computing power has been used to tackle issues such as climate changes, fusion energy, and other pressing scientific challenges. These computations produce a tremendous amount of data; however, many of the data analysis programs currently only run a single processor. In this work, we explore the possibility of using the emerging cloud computing platform to parallelize such sequential data analysis tasks. As a proof of concept, we wrap a program for analyzing trends of tropical cyclones in a set of virtual machines (VMs). This approach allows the user to keep their familiar data analysis environment in the VMs, whilemore »

Molecular simulation of rheological properties using massively parallel supercomputers
Advances in parallel supercomputing now make possible molecularbased engineering and science calculations that will soon revolutionize many technologies, such as those involving polymers and those involving aqueous electrolytes. We have developed a suite of messagepassing codes for classical molecular simulation of such complex fluids and amorphous materials and have completed a number of demonstration calculations of problems of scientific and technological importance with each. In this paper, we will focus on the molecular simulation of rheological properties, particularly viscosity, of simple and complex fluids using parallel implementations of nonequilibrium molecular dynamics. Such calculations represent significant challenges computationally because, in ordermore » 
Solving a Large Scale Thermal Radiation Problem Using an Interoperable Executive Library Framework on Petascale Supercomputers
We present a novel methodology to compute the transient thermal condi tion of a set of objects in an open space environment. The governing energy equa tion and the convective energy transfer are solved by the sparse iterative solvers. The average radiating energy on a set of surfaces is represented by a linear system of the radiosity equations, which is factorized by an outofcore parallel Cholesky decomposition solver. The coupling and interplay of the direct radiosity solver us ing GPUs and the CPUbased sparse solver are handled by a light weight software integrator called Interoperable Executive Library (IEL). IEL managesmore » 
On scaling optimization of highintensity, lowbeamloss RF linacs for neutron source drivers
RF linacs providing cw proton beams of 30250 mA at 8001600 MeV, and cw deuteron beams of 100250 mA at 3540 MeV, are needed as drivers for factory neutron sources applied to radioactive waste transmutation, advanced energy production, materials testing facilities, and spallation neutron sources. The maintenance goals require very low beam loss along the linac. Optimization of such systems is complex; status of beam dynamics aspects presently being investigated is outlined.
