job配置
Workflow : 配置了5个step
节点配置:
接下来，基于两个节点，调整Workflow中的Strategy，配置Thread Count，以及配置Orchestrator中Random Subset进行job的并行测试。
Node First测试
-
Thread count = 1，Orchestrator = None，logout为:
-
Thread count = 1，Orchestrator = 1，logout为:
-
Thread count = 1，Orchestrator = 2，logout为:
-
Thread count = 2，Orchestrator = None，logout为:
-
Thread count = 2，Orchestrator = 1，logout为:
-
Thread count = 2，Orchestrator = 2，logout为:
Parallel测试
-
Thread count = 1，Orchestrator = None，logout为:
-
Thread count = 1，Orchestrator = 1，logout为:
-
Thread count = 1，Orchestrator = 2，logout为:
-
Thread count = 2，Orchestrator = None，logout为:
-
Thread count = 2，Orchestrator = 1，logout为:
-
Thread count = 2，Orchestrator = 2，logout为:
Sequential测试
-
Thread count = 1，Orchestrator = None，logout为:
-
Thread count = 1，Orchestrator = 1，logout为:
-
Thread count = 1，Orchestrator = 2，logout为:
-
Thread count = 2，Orchestrator = None，logout为:
-
Thread count = 2，Orchestrator = 1，logout为:
-
Thread count = 2，Orchestrator = 2，logout为:

job执行线程监控
job配置:
job线程运行情况:
总结
- 在Orchestrator不做选择时，默认按照节点名排序执行，可选择排序方式
- 在Orchestrator中Random Subset选择 <b>1</b> 时，job最终只在一个节点执行，与采用哪种形式的Strategy，和Thread Count无关
- 即使在Node First模式下，调整Orchestrator节点数和Thread Count，可以实现节点的并行执行
- Parallel执行，是job中Step并行执行，即step执行不会按照step顺序执行
- Sequential方式，每个Step按照节点顺序执行, 当所有节点的上一个job step执行完，才会在所有节点执行下一个job step
