I'm trying to compare the performance of threaded programs (on Linux). Since the programs use different thread synchronization methods and different lock granularity, running the programs on a shared server or desktop would not be good, since the other tasks may interfere with the scheduling of my programs. I don't have dedicated hosts, so I thought that using qemu would be a good option.
What I want to know is:
- Are there any alternatives for this task?
- I suppose that there is no way to reproduce scheduling done by guest Linux system on qemu, if I - need to? (Suppose my program goes unusually skow or fast -- I'd like to know if I can run it again, but keeping exactly the same scheduling for its threads). Or is there a way?
