Are you doing this from a checkpoint or from boot? If you're doing it from boot, that's probably nowhere near enough. > And another question is there any way to make that all the CPUs > execute the same number of instructions?. The reason for that is that > I am comparing different algorithms in the cache, and when I run for > example algorithm A, the CPU 3 execute 4e6 instructions and when I run > algorithm B the CPU 3 execute 4.5e6.

A mode like this has been requested many times, but as far as we can tell, this leads to a bogus methodology, so we don't have it. The problem is that to do this, you'd have to stop CPUs which would throw off what is going on. I think the best alternative is to dump statistics each time a CPU hits the cycle count, and then you can compare the statistics dumps for each cpu separately. This way, you're at least maintaining the steady state and not experiencing cool down effects like the thing above would suffer.
