I need to run a long evaluation on my research group machines at university (Scientific Linux 6 , Mathematica 9). I just connect via ssh and work on math text-based environment. I can't find a way to let MathKernel processes go on when I log-out the ssh connection. I tried to put them in background using & and nohup, and I also tried to "daemonize" them, but no one of these attempts worked. Processes start properly, and they generate the output files they are supposed to. I can monitor them using "top" command on a secondary shell, and I can see them die when I close the primary shell or I exit the ssh connection on it. I read about some issues Mathematica has with csh/tsch shells, but i did not find a valid solution to my problem. Can someone suggest a possible solution?
