For support of the world-wide ITER (International Thermonuclear Experimental Reactor) project [1], large scale numerical simulations will be a necessity. Plasma turbulence simulations play a key role for the design, construction and optimization of the necessary fusion devices. The simulations will be so compute and memory intensive that applications must be able to efficiently use tens of thousands of processors. Highly scalable applications are mandatory. In Europe, within the DEISA supercomputing grid project, the DEISA Extreme Computing Initiative supports application enabling work and usage of Europe's most powerful supercomputers for challenging projects. With all support of the DEISA Extreme Computing Initiative and the DEISA Joint Research Activity in Plasma Physics, leading plasma turbulence simulations have been enabled for hyperscaling and for efficient and portable usage in the heterogeneous DEISA grid. Here we report about the large scale applications GENE and ORB5 with high relevance for ITER. GENE, a so-called Vlasov-code, was parallelized to such a high degree that efficient usage on 32,768 processors could be demonstrated. The PIC code ORB5 was enabled for hyperscaling especially through application of the domain cloning concept. Efficient usage of ORB5 code could be demonstrated on 8192 processors. |
