Hallo,

is there any posibility to suspend some application to disk?

You might want to take a look at Condor. It is designed to allow you
to submit long-running jobs to a batch queue. The jobs are sent to
whatever workstation happens to be available on the local net, where
they are run, periodically saving themselves. All system calls go
through a modified library that routes them over the net to the host
machine, so it's mostly only good for computationly-heavy jobs.

For X apps, though, it's much harder to do it, as you have program
state both in the application process and in the X server. You would
have to somehow save not only the state of the application, but the
state of all socket connections and enough information to reestablish
them.

Where do I find information about Condor?

Reading through the condor specs, I find a lot of information there, but
none regarding my problem. Could you please be more specific?

Condor checkpoints (saves the entire state to disk) processes
periodically. It does this both for reliability and for process
migration. It's probably not exactly what you're looking for, but you
could probably use it as a start if you want to implement something.
