Pretend Systems doing real Work
Simulated Systems let some things be done which are not easily possible
using other means. Have you ever wanted to:
- fork an entire running system (where system = hardware + OS)
- so you can follow both branches during decisions in testing runs?
- build a simulated network starting from your existing firewall and
- build a beowulf using just one computer?
- email your whole computer to a friend?
- set breakpoints on your hardware?
- write code for hardware that doesn't exist or you haven't got?
- boot your own personal 32-processor UltraSPARC, S/390
mainframe, Itanium or completely obsolete 16-bit architecture?
- create memory errors in your hardware and observe what the OS does?
There are some interesting problems and questions:
- what about preserving state when crossing over between real and
- licensing... some big companies get upset when free (and non-free)
simulated systems are used to run their OS or other software
- how can we know if the simulated system is a good implementation of
Scripting by James and Bernard.
