2. nvidia-smi -l SEC, --loop=SEC
Continuously report query data at the specified interval, rather than the default of just once. The application will sleep in-between queries. Note that on Linux ECC error or XID error events will print out during the sleep period if the -x flag was not specified. Pressing Ctrl+C at any time will abort the loop, which will otherwise run indefinitely. If no argument is specified for the -l form a default interval of 5 seconds is used.
以指定的時間間隔連續報告查詢數據，而不是默認的一次。應用程序將在中間查詢之間休眠。請注意，如果未指定 -x 標誌，則在 Linux ECC 錯誤或 XID 錯誤事件將在睡眠期間打印輸出。任何時候按 Ctrl + C 都會中止循環，否則循環將無限期地運行。如果沒有爲 -l 表單指定參數，則使用默認的 5 秒間隔。
使用默認值，每 5 秒間隔刷新一次。
strong@foreverstrong:~$ nvidia-smi -l
每 5 秒間隔刷新一次。
strong@foreverstrong:~$ nvidia-smi -l 5
3. watch -n 2 nvidia-smi
每 2 秒間隔刷新一次。
strong@foreverstrong:~$ watch -n 2 nvidia-smi
每 9 秒間隔刷新一次。
strong@foreverstrong:~$ watch -n 9 nvidia-smi
