Different proposal:

Let's say we have 2 Linux machines. Identical hardware, identical libs.

I'd like to run a simple program on one machine, and then during mid-calculation, would like to transfer the running program to the other machine.

Is this doable?

if you put you program in a qemu/kvm VM then it just works

I was completely blown away when I first experienced it. My code running in a VM never even noticed any downtime. All the network connections are preserved and so on.
