Hello again,

I think i have implemented all types of Locks: Spinlocks with
a backoff mechanism, the array based locks, and distributed locks etc.
and i think i have understood them well: the fair Locks such as
the Ticket spinlock and the Anderson Lock and the MCS lock and
my scalable distributed Lock that is fair when there is contention and 
that avoid starvation all of them do not scale and become slow if the 
number of threads are greater than the number of cores, but the unfair 
locks such as the Spinlock with backoff and my scalable distributed 
Lock(the version that is unfair) will scale even if the number of 
threads are greater than the number of cores.


This is very important to understand.

I have implemented an enhanced version of the scalable Anderson Lock
and i will put it tomorrow on my website.


So be smart please...



Thank you,
Amine Moulay Ramdane.
