Progress in Performance Portability of the XGC Plasma Microturbulence Codes

Speaker: Dr. Ed D’Azevedo

The XGC plasma microturbulence particle-in-cell code models transport in the edge region of a tokamak fusion reactor. XGC scales to over 18,000 nodes/GPUs on Cray XK7 Titan and over 64000 cores on Blue Gene/Q Mira. XGC is selected as one of the CAAR applications. We present our progress and lessons learned in achieving high performance in porting the collision kernel using OpenACC on GPU.
