How to continue running in intel fortran after the computer is abruptly shut off?

maryamsdr · April 20, 2016, 08:41

Hello everybody,
I've been running a transient problem in Intel FORTRAN compiler and my computer was abruptly shut down. I don't want to start the running again. It takes a lot of time. So can anyone tell me what should i do to continue the calculation without starting at initial time?
Is there any settings in Intel FORTRAN to pause the running when the computer
suddenly was shut down?

The old-time solution (say 50 years ago) was check-point dumps. Every so often you wrote out information necessary to restart/continue your computation to tape. If a failure occurred (as it often did in those days) you could go back to the last checkpoint and read in the data to continue. Some years ago when my computer was much slower (and sometimes failed because of heat generated in the cpu in long compute-bound solutions) I used this for long-running benchmark problems, but now that my personal computer is much faster and more reliable I don't do this. Still, it can be a relatively easy addition to a program.
