Re: A new scalability mathematical model better than Amdahl's law

I have thought more about my mathematical model
I have not take into account a factor, and there is still a problem with my mathematical model.
When . in the worst case, all threads are waiting for the lock , my equation works.
For physical contention , my mathematical model works, and it does predict the retrogade throuput.
To model for example my lock-free ParallelQueue or lock-free
or lock-free flqueue under contention, it works, and it does predict the
But there still a problem with my mathematical model, if there is contention , and the scheduler schedules threads other than the ones that are waiting on the lock, my mathematical model doesn't work correctly .
But it was a good attempt from my part to try to find a general scalability equation that also predict the retrograde throuput.
