Hello...


My Universal Scalability Law for Delphi and FreePascal was updated to
version 3.22

I have implemented and enhanced this powerful tool.

I have included a 32 bit and 64 bit windows and linux executables called
usl.exe and usl_graph.exe inside the zip, please read the readme file
to know how to use it, it is a very powerful tool.

Now about the Beta and Alpha coefficients of USL:

Coefficient Alpha is: the contention

And

Coefficient Beta is: the coherency.

Contention and coherency are measured as the fraction of the sequential
execution time. A value of 0 means that there is no effect on
performance. A contention factor of 0.2, for instance, means that 20% of
the sequential execution time cannot be parallelized. A coherency factor
of 0.01 means that the time spent in the synchronization between each
pair of processes is 1% of the sequential execution time.


Also there is something very important to know, and here it is:

So to optimize more the criterion of the cost for a better QoS, you have
to choose a good delta(y)/delta(x) to optimize the criterion of the cost
of your system and you have to balance better between the performance
and the cost. You can read about my powerful tool and download it from:
