I'm trying to start a run of LAMMPS (which takes an input file) with mpiexec on multiple processors. I want to combine this with nohup so that I can log off the node. I've used the syntax below successfully on one cluster, but it doesn't work on the new one I'm using. Any suggestions would be helpful.
First, I have a script:
Now, I call that script with nohup via:
This starts the lammps job just fine, on 8 processors. However, when logging out of the node, the jobs die. Checking the nohup.out, I get the final line:
"mpiexec noticed that process rank 1 with PID 37372 on node whatever exited on signal 1 (Hangup)."
Isn't that what nohup is supposed to be preventing? I've seen the redirecting to /dev/null thing mentioned around the web, but I'm either using it wrong, or it's ineffective. Help!?!

Hello,
I am trying to find a way to send several sequential commands via SSH to a remote box in a single command.
Thoughts so far:
1) Can I put them into a function and call the function within the ssh command?
e.g.
ssh <targetserver> $(functionx)
No - then it calls the function in... (4 Replies)

nohup
NOHUP(1) User Commands NOHUP(1)NAME
nohup - run a command immune to hangups, with output to a non-tty
SYNOPSIS
nohup COMMAND [ARG]...
nohup OPTION
DESCRIPTION
Run COMMAND, ignoring hangup signals.
--help display this help and exit
--version
output version information and exit
If standard input is a terminal, redirect it from an unreadable file. If standard output is a terminal, append output to 'nohup.out' if
possible, '$HOME/nohup.out' otherwise. If standard error is a terminal, redirect it to standard output. To save output to FILE, use
'nohup COMMAND > FILE'.
NOTE: your shell may have its own version of nohup, which usually supersedes the version described here. Please refer to your shell's doc-
umentation for details about the options it supports.
