Hi Tom, Johnathan, Thanks your reply. Hi Marcus, Seems your conclusion is make sense. I think it might relate with buffer size which was allocated in "flat_flowgraph.cc / allocate_buffer" // *2 because we're now only filling them 1/2 way in order to // increase the available parallelism when using the TPB scheduler. // (We're double buffering, where we used to single buffer) int nitems = s_fixed_buffer_size * 2 / item_size But I don't know why do it can increase parallelism? 在 2015年06月19日 22:48, Johnathan Corgan
