测试并发执行效率的测试程序，通过修改参数可以观察任务数量、并行传输数据量、并行子任务计算量对整个并发提升效率的影响。(To test the efficiency of concurrent execution, we can observe the influence of the number of tasks, the amount of parallel data transferred and the amount of parallel subtask computation on the efficiency of concurrent promotion by modifying the parameters.)
