资源配置参数 task_cores 和 computing_partitions 的含义

从 https://fate-flow.readthedocs.io/en/v1.11.1/fate_flow_resource_management/ 文档上看，其实我只需要配置 task_cores 就能设定任务使用的cpu资源，然而我实测下来发现：

a. task_cores = 12 & computing_partitions = 12 b. task_cores = 24 & computing_partitions = 12 c. task_cores = 24 & computing_partitions = 24

任务耗时 a 约等于 b 大于 c。且从机器监控上看，cpu利用率也是 a 约等于 b 小于 c。

也就是说，仅靠 task_cores 的配置是不够的，还必须同步去配置 computing_partitions 的值才能达到最佳的效果。这个信息与文档中的表述似乎不太一致，不确定到底是为什么。求指教。

总Core：40 Upload指定的分区数：8 OS：CentOS7 FATE：1.11.1 配置方式： "job_parameters":{ "common":{ "computing_partitions":12, "task_cores":24 } }

computing_partitions应该是计算的时候数据的分区数，而task_cores对应的是使用多少个cpu进程去处理这个数据，每个cpu进程每次会拿一个分区的数据去进行计算，直到处理完所有分区。所以task_cores应该是<=computing_partitions的。当不设置的时候，task_cores应该会等于computing_partitions。
