= 【1.配置】 =
== 【1.1 Haizea Configuration File】 ==
|| 從上圖架構知道，要使用 Haiea 的第一步便是要撰寫一篇好的 Haizea Configuration File，官方文件說可以參考範例檔 /usr/share/haizea/etc/sample_trace.conf 和 sample_trace_barebones (兩個文件內容一樣，只差再第2份沒註解)，文檔中要注意的地方是 option 的設定和配置 ||
* 以下面範例來解說 option，便是'''『模擬』''' '''2006-11-25 下午1點'''開始執行任務在 '''4台有1顆CPU 和1G Ram 的機器'''上執行 ([simulation]->屬性名稱，startime、resources->屬性細部設定)
{{{
#!sh
[simulation]
starttime: 2006-11-25 13:00:00
resources: 4 CPU:100 Memory:1024
}}}
* [[Image(quickstart_leasegraph2.png,width=300px)]]
* [http://haizea.cs.uchicago.edu/manual/node63.html#app:conffile 參考的屬性值]
[[BR]]
== 【1.2 Tracefile File】 ==
|| 而 Tracefile 便是在 Haizea Configuration File 中的 [tracefile] 屬性指定||
{{{
#!sh
[tracefile]
tracefile: /usr/share/haizea/traces/sample.lwf
}}}
* 此 Tracefile 範例檔的格式為 LWF/Lease Workload Format (類似 XML 的格式)
{{{
#!sh
A simple trace where an AR lease preempts a
best-effort lease that is already running.
}}}
* [http://haizea.cs.uchicago.edu/manual/node71.html#app:lwf XML 格式參考]

= 【2.開始模擬】 =
||現在我們使用已寫好的範例 configuration(sample_trace.conf) 和 tracefile(sample.lwf)，便可透過haizea 指令開始執行模擬 (參數 -c 為指定設定檔)||

* 此結果輸出主要有三類：'''RM'''(Resource Manager)、'''TFILE'''(!TraceFile)、'''CLOCK'''
* RM Starting resource manager：啟動資源管理者
* TFILE Loading tracefile /usr/share/haizea/traces/sample.lwf：載入 tracefile
* TFILE Loaded workload with 0 requests ()：此範例檔並無租約要求
* CLOCK Starting simulated clock：開始模擬的 clock
* CLOCK Simulated clock has stopped：停止模擬的 clock
