This is the default operating mode for Nvprof. It outputs a single result line for each instruction such as a kernel function or CUDA memory copy/set performed by the application. For each kernel function, Nvprof outputs the total time of all instances of the kernel or type of memory copy as well as the average, minimum, and maximum time. | This is the default operating mode for Nvprof.
