Re: A new algorithm...

Hello,

Notice the backoff mechanism on the pop() side of my algorithm like this,

t:=backoff.delay;
for i:=0 to 40*t do asm pause end;

this backoff mechanism is mandatory cause the lockfree mechanism do 
generate more cache-coherence traffic under high contention, hence
with this backoff mechanism my algorithm will scale better on
more and more cores.


I have tested this backoff mechanism and it is working perfectly.




Thank you,
Amine Moulay Ramsdane.
