繼伺服器掛掉之後,把之前的資料救回來,在重灌的環境下,並重新安裝 Nvidia Driver,執行效能完全一致。
在 sandbox 上運作則是完全失靈,只好 strace 一次沒有結果,-f 遞迴展開所有 system call,繞了半圈才發現 nvidia-compiler.so 繞了好幾個目錄都找不到,根據版本號命名果然兇狠。
至於為什麼外部可以直接運行 ...

當運行其他裝置的情況下 (如 GPU, MIC),需要使用 strace -f ./sandbox 10 16777216 ./main 查閱調用情況,特別注意到 strace 只開放給有 root 權限的情況下使用。
strace -f ./sandbox 10 16777216 ./main
strace
sudo strace -f ./sandbox ... 2>error.log
sudo
Sorry, something went wrong.
在 strace 輸出 log 檔中,若出現 Too many levels of symbolic links,表示之前使用 ln -s ./pathA ./pathB 相對路徑,改用絕對路徑便能解決此問題。
Too many levels of symbolic links
ln -s ./pathA ./pathB
