Advanced accelerator simulation research: miniaturizing accelerators from kilometers to meters

Optimizing the Advanced Accelerator Simulation Framework Synergia Using OpenMP

Synergia is an advanced accelerator framework widely used by accelerator community. However, its performance suffers significantly from the high communication requirement. In this paper, we address this issue by replacing the flat MPI programming model with the hybrid OpenMP+MPI programming model. We describe in detail how the code has been parallelized in OpenMP and what the challenges are. Th...

Community petascale project for accelerator science and simulation: Advancing computational science for future accelerators and accelerator technologies

The design and performance optimization of particle accelerators are essential for the success of the DOE scientific program in the next decade. Particle accelerators are very complex systems whose accurate description involves a large number of degrees of freedom and requires the inclusion of many physics processes. Building on the success of the SciDAC-1 Accelerator Science and Technology pro...

An Advanced State Estimation Method Using Virtual Meters

-  Power system state estimation is a central component in energy management systems of power system. The goal of state estimation is to determine the system status and power flow of transmission lines. This paper presents an advanced state estimation algorithm based on weighted least square (WLS) criteria by introducing virtual meters. For each bus of network, except slack bus, a virtual meter...

Theory and Simulation of Plasma Accelerators - Particle Accelerator Conference, 1995., Proceedings of the 1995

We report on some of the recent theoretical and computational results at UCLA and USC on plasma-based accelerator concepts. Topics discussed include beat-wave excitation from short-pulse lasers, self-trapped electron acceleration from self-modulational instabilities and wakefield excitation in preformed channels. INTRODUCTION For some time now plasma structures have been considered as the basis...
