Default recovering data after electricity failure (F12).

Hello,

I've F12 installed on my PC.
An electricity cut happened while running a program on the terminal line. A general electricity cut nothing to do with PC hardware failure. Hence PC restarted itself after electricity was back however the program that was runing terminated before completion.


Is it possible to recover the memory and resume the program where it had to terminate unexpectedly.

The program was running for 2-3 weeks, hence don't want to start the program from fresh.

Regards,

NC

Nermin,



That's a hard question to answer without knowing more about "a program". If it was written to "read, compute, write, cycle back", you could probably start it up again at will. On the other hand, if it was one long plug & chug (say, looking for the 30 millionth digit of pi), chalk it up to an object lesson in the value of an UPS and start over at the beginning.

It depends on the design of the program but generally speaking, it's not
possible. Some programs save datafiles and the like as they run so in those
cases it might be possible to recover and carry on from a mid-point in the
program run but unless the program is specifically designed to do that it's
pretty unlikely.

A UPS is your best solution for the future (and a smart thing to have anyway).

Yes it was mainly "read, compute,write" cycle.
It was a perl program, running HMMer (hidden markov model program) on a set of genome data.


I'm not familiar with UPS...???

It's gone when the power goes.

I would check the documentation and see whether the software checkpoints
itself so it can be restarted from a checkpoint. However that is an
application thing.
