The parallel execution test in gem_exec_nop is unrealistic, and in fact chooses a pessimal distribution of work to multiple engines. The first patch in this sequence adapts it to send multiple batches (currently 64) to each engine, in a round-robin fashion, thus keeping the engines fed adequately with workstreams. The second patch simply changes the output of this same test to make it more obvious what measurements are made and what results can be calculated from them.
