#2285 — About my threadpool engine...

Hello,

I have used my threadpool engine as a scalable FIFO queue,
and have done some benchmarks on a quad cores using both
the execute() method and my new Exec()  method and here
is the scalability numbers:

Using one global lockfree queue, it gave a negative scalability of  -2.7x

Using mutiple lockfree local queues with work-stealing
and using the execute() method , it can go up to 2.5x scalability

And using multiple lockfree local queues with work-stealing
and using my new Exec() method , it can go up to 3.8x scalability.


Those benchmarks were run under Delphi.

But on Freepascal my threadpool engine is not scaling cause there it's a 
problem with the freepacal compiler.

You can download my threadpool engine and all my parallel libraries from:

Thank you,
