Hello all,


I have updated Threadpool to version 1.3 - a stable version -

Lock-free ParallelQueuerb and lock-free RingBuffer have been added


Author: Amine Moulay Ramdane


Language: FPC Pascal v2.2.0+ / Delphi 5+:

http://www.freepascal.org/


Operating Systems: Win , Linux and Mac (x86).


Description:


Lock-free Thread Pool Engine.


The following have been added:


-- Lockfree ParallelQueue for less contention and more efficiency
or it can use lockfree_mpmc - flqueue that i have modified, enhanced
and improved... - ...


- It uses a lock-free queue for each worker thread and work-
stealing
- for more efficiency -

- The worker threads enters in a wait state when there no job in the
lock-free queues - for more efficiency -


- You can distribute your jobs to the worker threads and call any
method with the threadpool's execute() method.


Look into defines.inc there is many options:


ParallelQueue: it uses lock-free ParallelQueue - very efficient -
Lockfree_MPMC: it uses lockfree_MPMC
ParallelQueuerb: it uses lock-free ParallelQueuerb (New)
RingBuffer: it uses lock-free RingBuffer (New)
SINGLE_PRODUCER: for a single producer (thread)
MUTIPLE_PRODUCER: mutiple producer (threads)
CPU32: for 32 bits architecture



Required FPC switches: -O3 -Sd -dFPC -dWin32 -dFreePascal

-Sd for delphi mode....

Required Delphi switches: -DMSWINDOWS -$H+

For Delphi 5,6,7 use -DDelphi

For Delphi 2005,2006,2007,2009,2010+ use the switch -DDELPHI2005+

Please look at the examples test.pas,test_pool.pas and
test_thread.pas insode the zip...


Note: test_pool.pas does require Delphi 5+, test.pas and
test_thread.pas works with both FreePascal and Delphi


You can download the new and stable version 1.3 from:
