Description

The usage of grid infrastructures for fusion research has provided interesting results that open themselves new lines of research. There is an important number of applications running in the grid with different schemes and structures, which has allowed to gain experience in porting different types of codes. For instance, we can find sequential applications, PIC codes and optimisation procedures based upon genetic algorithms. The use of the grid for data management is totally new in fusion and the results of this pilot experience will be shown in this session. Finally, an experience of a complex workflow between an application that runs in a share memory computer and in the grid will be also presented. This last experience opens a wide range of possibilities for building complex workflows among different types of applications that run in different infrastructures.

Scientific results obtained using grid technology

Oral

New 3 applications were ported in the RFUSION VO within the EGEE-III project. Grid technology was applied for tokamak plasma geometry optimization (earlier the same techniques was used for stellarators), for modeling turbulence behavior near the plasma edge in tokamak T-10 and modeling formation of carbon nanotubes at the surface of vacuum discharge chambers in thermonuclear installations....

Planned or on-going scientific work using the grid

Oral

The ASTRA code, which has been developed at Kurchatov Inst. and IPP-Garching, solves diffusion equations subject to magnetic fusion plasmas. This code is being run on a shared memory machine at CIEMAT, which makes it difficult to scale. To begin with, after analyzing the different external modules called by ASTRA, a Ray Tracing one was chosen for Grid execution. In this way, all jobs related...

Scientific results obtained using grid technology

Oral

The use of evolutionary and genetic algorithms to improve the configuration of nuclear fusion devices is an optimal approach thanks to grid computing, as compared to other approaches such as brute-force algorithms. The computational cost of the application used to improve the equilibrium, one of the characteristics of fusion devices, means that the use of grid becomes fundamental to carrying...
