我查看了lastcomm输出，发现nvidia-smi当前用户（其名称只是“用户”）大约每 5 秒执行一次命令。我很好奇这是否是正常情况？详细信息如下：
# lsb_release -d

# uname -srvmpio
Linux 5.4.0-26-generic #30-Ubuntu SMP Mon Apr 20 16:58:30 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
然后
# lastcomm nvidia-smi

我在这里删除了大部分输出，因为直到开始为止几乎都是相同的：

当然，用户不会nvidia-smi手动运行。那么，这种情况是否正常？谁又为何如此频繁地运行它？
