使用Mandelbrot集測試Linux集羣的問題

Question

我有一個運行Ubuntu 11.04和MPICH2 1.4的六節點集羣。我正在嘗試使用Mandelbrot集測試圖形。假定在MPICH2子目錄中找到的pmandel可執行文件應該使用羣集中的所有節點在屏幕上顯示Mandelbrot分形，並且迄今爲止發現的所有方向都告訴我「使用pmandel exec」爲這個測試。沒有exec - 只有pmandel.c，pmandel.h和pmandel.pd。我想我應該編譯pmandel.c創建EXEC，但我得到以下錯誤，當我嘗試：

cs_lab@daedalus01:~/MPICH2/mpich2-1.4-source/src/mpe2/src/graphics/contrib/mandel$ mpic++ -c pmandel.c

它只是看起來像標準的編譯錯誤給我。但是爲什麼MPICH2會發布錯誤文件？我確定我做錯了什麼，但我無法弄清楚如何運行這個測試。任何幫助將不勝感激。

Answer 1

如果您配置了MPICH2的副本--enable-mpe（或者，更可能的是，沒有--disable-mpe），那麼應該有一個src/mpe2/src/graphics/contrib/mandelMakefile。嘗試從該目錄運行make，看看是否會爲您建立pmandel。

綜上所述，當我運行該程序時，它一開始工作，然後在我嘗試通過拖動一個新框放大時進行分段。因人而異。正如評論中提到的awoodland，這是contrib代碼，所以MPICH2團隊沒有寫它。自述文件中列出的作者似乎已經從阿貢移居，因此你不可能從他那裏得到任何支持。

Answer 2

由於配置問題，您的MPE頭部可能是空的。試試這個：

$ cat <YOUR MPICH DIRECTORY>/include/mpe.h 

這：

$ cat <YOUR MPICH DIRECTORY>/include/mpe_graphics.h 

如果你看到任何警告信息，你應該考慮編制和source重新安裝。
