Default A new scalability mathematical model better than Amdahl's law - 09-18-2010 , 01:27 AM






Hello,


I have wrote an article that speaks about my new scalability
mathematical model that is better than Amdahl's law:

Hello all,

I have thought more about my mathematical model

http://pages.videotron.com/aminer/scalability.htm


I have not take into account a factor, and there is still a problem
with my mathematical model.

I explain:

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
Ringbuffer
or lock-free flqueue under contention, it works, and it does predict
the
retrogade throuput.

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.
