Note that this option will only have an effect if the warpx.use_Hybrid_QED flag is also triggered. + * ``warpx.do_device_synchronize_before_profile`` (`bool`) optional (default `1`) + When running in an accelerated platform, whether to call a deviceSynchronize around profiling regions. + This allows the profiler to give meaningful timers, but (hardly) slows down the simulation. + * ``warpx.sort_int`` (`int`) optional (defaults: ``-1`` on CPU; ``4`` on GPU) If ``<=0``, do not sort particles. If ``>0``, sort particles by bin every ``sort_int`` iteration. It is turned on on GPUs for performance reasons (to improve memory locality). |
