Hello,


Distributed Reader-Writer Mutex 1.0


Description:

Distributed Reader-Writer Mutex, ported by Amine Moulay Ramdane
from the Dmitry Vyukov C++ Distributed Reader-Writer Mutex to
 Object Pascal, I have included the following Reader-Writer Mutexes
inside this Distributed Reader-Writer mutex: TOmniMREW a light weight
MREW that is very fast and TMultiReadExclusiveWrite from JCL and
nowboth of them can scale better, and i have modified a little bit
the Dmitry Vyukov Distributed Reader-Writer Mutex, i have not
used GetCurrectProcessor() but i have used  GetCurrectThreadID()
like this: nbr := getcurrentthreadid mod proc_count; i have provided you
with the source code, please take a look at the source code to understand 
better.


Language: FPC Pascal v2.2.0+ / Delphi 7+: http://www.freepascal.org/

Operating Systems: Win and Linux (x86).

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

-Sd for delphi mode....

Required Delphi switches: -DMSWINDOWS -$H+

For Delphi use -DDelphi

And inside defines.inc you can use the following defines:

{$DEFINE CPU32} for 32 bits systems

{$DEFINE CPU64} for 64 bits systems

{$DEFINE TOmniMREW} to use Omnithread MREW

{$DEFINE TMultiReadExclusiveWrite} to use the jcl TMultiReadExclusiveWrite
