There are many optimization tasks in accelerator physics: for example, fitting twiss parameters or maximizing dynamic aperture. Optimization algorithms can be generalized to encompass a larger class of problems not restricted to accelerator physics. Modern computational methods provide means to do that, allowing us to treat one-dimensional and… (More)
FACETS (Framework Application for Core-Edge Transport Simulations), now in its second year, has achieved its first coupled core-edge transport simulations. In the process, a number of accompanying accomplishments were achieved. These include a new parallel core component, a new wall component, improvements in edge and source components, and the framework… (More)
The FACETS project aims to provide computational tools for whole device simulation of tokamak transport for use in fusion applications. The framework provides flexibility by allowing users to choose the best model for a given physics target. Our goals are to develop accurate transport solvers using neoclassical and turbulent fluxes with varying degree of… (More)
The paper presents a prototype of the NSLS-II high level application environment including key middle layer servers, such as Machine, Online Model and Virtual Accelerator. The proposed environment is developed and evaluated on top of EPICS-DDS, an open source implementation of the DDS standard interface based on the EPICS Channel Access protocol.
Recent advances in computer science have made development and management of large-scale distributed and high-performance applications possible. Examples of such advances are Grid and Component technologies. In this paper we share our experience in bringing Grid and Component technologies into fusion applications.
