Okay, interpid readers.... have we tried this one? Can a process be deliberately halted and a core dumped (kill -3 PID for instance) such that it can be later restarted ? We run lengthy simulations here which I would like to be able to stop, reboot the machine and then restart. Is there a way besides building it into the program itself? Along the same lines, I would like to stop a process running on a 3/50 and restart it on a different 3/50 or a 3/180 (running v3.5).

See volume 6 issue 68. It mentions a library called "chkpt" by Dave Curry, but he implies that it only works on 4.3BSD VAXen. It's an interesting problem. I don't think it can be solved without some co-operation from the program. That co-operation could be as simple as linking against an extra library which "shadows" certain system calls. --wnl ]]
