Hello,

I will compare the Exec() method of my threadpool engine to the bucketsort,
in the bucketsort algorithm, si if in the bucketsort the elements are
uniformly
distributed over an interval [a, b] and buckets have not significantly
different number of elements the scalability will be optimal.
It's the same with the Exec() method of my threadpool engine,
if the load is uniformly distributed over the local lockfree FIFO MPMC
queues the scalability will be optimal, so using multiple lockfree local
queues with work-stealing and using my new Exec() method , my threadpool
engine
used as a scalable FIFO MPMC queue can go up to 3.8x scalability on a
quadcores..

Now when i have used only a global lockfree queue on my threadpool engine,
my threadpool engine used as a scalable FIFO MPMC queue gave a negative
scalability of -2.7x on a quad cores


And using mutiple lockfree local queues with work-stealing
and using the execute() method , my threadpool engine used as
a scalable FIFO MPMC queue gave me 2.5x scalability on a quad cores.


Wha'ts important is that my threadpool engine is useful.
