591 TFLOPS Multi-trillion Particles Simulation on SuperMUC,on to make use of Hyperthreading. Finally we present results for weak and strong scaling experiments on up to 146016 Cores of SuperMUC at the Leibniz Supercomputing Centre, achieving a speed-up of 133k times which corresponds to an absolute performance of 591.2 TFLOPS.

Heterogeneous Programming and Optimization of Gyrokinetic Toroidal Code and Large-Scale PerformanceIA M2050 GPUs to Intel Xeon X5670 CPUs. Strong and weak scaling studies have been performed using actual production simulation parameters, providing insights into GTC’s scalability and bottlenecks on large GPU supercomputers.

Improving Performance Portability in OpenCL Programs,We further demonstrate that proper tuning could improve the OpenCL portable performance from the current 15% to a potential 67% of the state-of-the-art performance on the Ivy Bridge CPU. Finally, we evaluate the current OpenCL programming model, and propose a list of extensions that improve performance portability.
