job配置
Workflow : 配置了5個step
節(jié)點配置:
接下來，基于兩個節(jié)點，調(diào)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(zhí)行線程監(jiān)控
job配置:
job線程運行情況:
總結(jié)
- 在Orchestrator不做選擇時，默認按照節(jié)點名排序執(zhí)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(jié)點執(zhí)行，與采用哪種形式的Strategy，和Thread Count無關(guān)
- 即使在Node First模式下，調(diào)整Orchestrator節(jié)點數(shù)和Thread Count，可以實現(xiàn)節(jié)點的并行執(zhí)行
- Parallel執(zhí)行，是job中Step并行執(zhí)行，即step執(zhí)行不會按照step順序執(zhí)行
- Sequential方式，每個Step按照節(jié)點順序執(zhí)行, 當所有節(jié)點的上一個job step執(zhí)行完，才會在所有節(jié)點執(zhí)行下一個job step
