Gyrokinetic toroidal simulations on leading multi- and manycore HPC systems
2011
Proceedings of 2011 International Conference for High Performance Computing, Networking, Storage and Analysis on - SC '11
The gyrokinetic Particle-in-Cell (PIC) method is a critical computational tool enabling petascale fusion simulation research. In this work, we present novel multi-and manycorecentric optimizations to enhance performance of GTC, a PIC-based production code for studying plasma microturbulence in tokamak devices. Our optimizations encompass all six GTC sub-routines and include multi-level particle and grid decompositions designed to improve multi-node parallel scaling, particle binning for
