Details
An expert group for high performance calculations was officially established on
20 May 2009 at the Max Planck Institute of Plasma Physics (IPP) in Garching near
Munich. The team, named "High-Level-Support-Team" and supported financially
by the European Union, should help researchers in the PPI to adapt their codes
of calculations so that the supercomputers can handle.
The objective of fusion research is to gain energy from the fusion of
nuclei of atoms similar to the Sun. To do this, researchers need to succeed in
confining the fuel in the form of ionized gas called plasma with magnetic
fields, on a stable and isolated, and heat it to over 100 million degrees. The
behavior of plasma complex is subject to numerous experimental facilities in
many of fusion. The next major milestone will be marked by the international
thermonuclear experimental reactor (ITER "the way" in Latin, , being built
in Cadarache.
The description of fusion plasmas by the calculation has changed in recent
years. The longer term objective is to achieve comprehensive computer
simulations of processes occurring in a fusion plasma, including the movement of
turbulence in the plasma processes in the marginal layer and the effect of
various heating procedures gas. To carry out such simulations, supercomputers
are needed: for example, the FF-HPC (High Performance Computer for Fusion),
reaching speeds of 100 teraflop computing / s (100 billion operations per
second), will be made available to researchers in the field of fusion research
center Jülich (FZJ). Pétaflopique a supercomputer, the fruit of cooperation
between Japan and Europe, should then be put at the service of the International
Center for fusion research (International Fusion Energy Research Center, IFERC, in Rokkasho from 2012 .Supercomputers with speeds exceeding the pétaflop /
s would be able to simulate entire volumes of 800 m3 plasma of ITER.
The codes currently used by researchers in the PPI, however, are not adapted to
such massively parallel architectures (or "Massive Parallel Processing). In
order to properly exploit the power of the supercomputer HPC-FF, Garching
specialists must adjust their calculations through ingenious mathematical
methods. "Five members of the group of experts, both with long experience in the
field of physical science, will work within the PPI and the computing center in
Garching (RZG, ). Four other experts work in other European fusion
laboratories, "says Prof. Dr. Sybille Günter, Director of "theory of tokamak at
IPP and Chairman of the HPC.Counsel for the HPC's goal, among others, to ensure
optimum use of the supercomputer in Jülich "With HPC-FF in Jülich and the group
of experts in PPI, European research in the field of Fusion is equipped with the
tools and knowledge necessary to prepare and interpret effectively the
experience of ITER. And we can develop models to design a demonstration power
plant, "says Prof.. Günter. The aim is also to prepare the European scholars
specializing in the field of fusion to the next generation of supercomputers
pétaflopiques computer: "We must begin with the preparation of research and
development of computer codes."
For now, the HPC project is funded under the European Fusion Development
Agreement (EFDA) over a period of 4 years.
