If you have a large calculation that you wish to run on another machine unattended, you may want to consider saving your inputs in a plain text file and then run the kernel in batch mode. This archived posting describes this process in greater detail. http://groups.google.com/groups?selm=6hp9f9%24d10%40smc.vnet.net This will allow you to start the computation on a remote machine as a background process and log out. Note that this does not protect you against a situation where someone may reboot the machine while the operation is in progress. There is no way to recover from that kind of problem. -- P.J.
