job配置
Workflow : 配置了5個step
節點配置:
接下來，基于兩個節點，調整Workflow中的Strategy，配置Thread Count，以及配置Orchestrator中Random Subset進行job的并行測試。
Node First測試
-
Thread count = 1，Orchestrator = None，logout為:
-
Thread count = 1，Orchestrator = 1，logout為:
-
Thread count = 1，Orchestrator = 2，logout為:
-
Thread count = 2，Orchestrator = None，logout為:
-
Thread count = 2，Orchestrator = 1，logout為:
-
Thread count = 2，Orchestrator = 2，logout為:
Parallel測試
-
Thread count = 1，Orchestrator = None，logout為:
-
Thread count = 1，Orchestrator = 1，logout為:
-
Thread count = 1，Orchestrator = 2，logout為:
-
Thread count = 2，Orchestrator = None，logout為:
-
Thread count = 2，Orchestrator = 1，logout為:
-
Thread count = 2，Orchestrator = 2，logout為:
Sequential測試
-
Thread count = 1，Orchestrator = None，logout為:
-
Thread count = 1，Orchestrator = 1，logout為:
-
Thread count = 1，Orchestrator = 2，logout為:
-
Thread count = 2，Orchestrator = None，logout為:
-
Thread count = 2，Orchestrator = 1，logout為:
-
Thread count = 2，Orchestrator = 2，logout為:

job執行線程監控
job配置:
job線程運行情況:
總結
- 在Orchestrator不做選擇時，默認按照節點名排序執行，可選擇排序方式
- 在Orchestrator中Random Subset選擇 <b>1</b> 時，job最終只在一個節點執行，與采用哪種形式的Strategy，和Thread Count無關
- 即使在Node First模式下，調整Orchestrator節點數和Thread Count，可以實現節點的并行執行
- Parallel執行，是job中Step并行執行，即step執行不會按照step順序執行
- Sequential方式，每個Step按照節點順序執行, 當所有節點的上一個job step執行完，才會在所有節點執行下一個job step
