If the output of the program is sent to the frame buffer, these few bytes of output can be read back with theglReadPixels()function. If the render target is in system memory, the rasterizer will write only a few bytes to system memory, where the CPU can retrieve the ...
The reason for this is to minimize the “tail” effect, where at the end of a function execution only a few active thread blocks remain, thus underutilizing the GPU for that period of time as illustrated in Figure 3. Figure 3. Utilization of an 8-SM GPU when 12 thread blocks with ...
