have time to read through all the docs. And i don't know in which PDF i should 
look for
this info. But, my implementation is very easy to tune. Just change the 
Actually it could be even made into static variable so that machines could set 
it before

 And my real HW has 16 CPUs per cluster, but i thought it's 
implementation-specific. Isn't
it ?
