MPI pbs輸出文件在運行時間內是否可用？

Question

我正在運行一個程序，並且正在使用調試模式。在調試模式下，程序會打印出一些有用的信息，並且我想在運行過程中檢查它。然而，我無法在輸出目錄中找到輸出文件..在代碼中可用，或者我可以在代碼結束時找到它。

Answer 1

文件的位置取決於扭矩/ PBS的配置方式。有時它們是在作業工作目錄中創建的，有時是在計算節點上創建它們並在作業完成後複製到工作目錄中。如果是這種情況，您應該能夠在PBS/Torque假脫機目錄中找到該輸出。/var/spool/torque/spool和/ var/lib/torque/spool是兩個開始尋找的地方。您也可以解決此通過重定向你的輸出到您指定的文件

mpirun -np 8 ./a.out > /home/neouyghur/job_output 

或

mpirun -np 8 ./a.out &> /home/neouyghur/job_output 

兩全輸出和錯誤。

您可能還想查看qsub手冊頁中的o，e，j和k開關，因爲它們也會影響輸出的處理方式。

Answer 2

如果您的輸出文件常常是網絡安裝位置，那麼你可以問管理員設置

$spool_as_final_name true 

在媽媽的配置文件。這將使輸出直接寫入其最終位置，而不是被其他地方假脫機，然後複製。
