Re: [Dmtcp-forum] IF a program can use dmtcp to rollback itself to a specialcheckpoint

[Kapil A. <ka...@cc...>]

I think this is doable. All you need is to exec into dmtcp_restart
program with the ckpt-image as the argument?

Do you know the specific point where you would want to do the rollback?

Also, on a related note, we have a reversible debugger FReD (Fast
Reversible Debugger). You can check it out here
https://github.com/fred-dbg. We haven't updated it lately, so it's
possible that it is broken right now. But if there is some interest,
we can talk more about it.
