[英]How to remotely run a program with SSH independent of my current computer
So I want to run a program from my Desktop, but I would like to have my Desktop "forget it", so that if my Desktop crashes or shuts down it won't affect the SSH program. 所以我想从我的桌面上运行一个程序,但是我想让我的桌面“忘记它”,这样,如果我的桌面崩溃或关闭,它将不会影响SSH程序。
In other words: I want the task to be executed on the remote computer independent of the computer, with which I'm sending the task. 换句话说:我希望任务可以在与我发送任务的计算机无关的远程计算机上执行。
Why would I wanna do this? 我为什么要这样做? Because I'm executing a huge task on a huge computer (64 cores computer), which should take days to evaluate, but I don't want my current computer to have to wait for it.
因为我正在一台大型计算机(64核计算机)上执行一项巨大的任务,这需要花费数天的时间进行评估,但是我不希望当前的计算机必须等待它。 The last time my Desktop froze, and I lost all the progress I had.
上次我的桌面冻结时,我失去了所有的进度。
I can imagine that this question has been answered a million times already, but I don't know what terminology I have to search for, and I don't know what this process is called. 我可以想象这个问题已经被回答了一百万遍了,但是我不知道我要搜索什么术语,也不知道这个过程叫什么。
Thanks. 谢谢。
nohup
nohup
Ubuntu : sudo apt-get install screen
Ubuntu:
sudo apt-get install screen
screen
then after you lost ssh session. 然后在您失去了ssh会话之后。
login to ssh again and then 再次登录ssh然后
screen -r
This will resume ssh session screen. 这将恢复ssh会话屏幕。
For more info man screen
有关更多信息的
man screen
You could use (on the remote big iron) the batch(1) command since you want batch processing : 您可以使用(在远程大型服务器上) batch(1)命令,因为您要进行批处理 :
local% ssh remotebigmachine
remotebigmachine% batch << EOB
./myprog param1 param2 param3 > output.txt
EOB
remotebigmachine% exit
In the above both local%
and remotebigmachine%
are shell prompts (in practice they are something different). 在上面,
local%
和remotebigmachine%
都是shell提示(实际上它们是不同的)。
BTW, for batch computation running many days, it is worthwhile to program some application checkpointing (because even supercomputers may have power outages or hardware issues). 顺便说一句,对于运行数天的批处理计算,值得对一些应用程序检查点进行编程(因为即使超级计算机也可能会出现断电或硬件问题)。
