Those look like interesting results. Do we have any idea why we are slow on CUDA on the RHS? Do we have any indication of actual speed compared with peak flops or bandwidth? Regards, David On Friday, July 11, 2014, Rathgeber, Florian <f.rathgeber10@imperial.ac.uk> wrote:
I have now added performance results for advection assembly (matrix + RHS). We can still claim (performance) portability to some degree across sequential, OpenMP and CUDA.

I'm concerned that there are no performance results at all. Do we not even have CPU results?
