Hello.
My Parallel Compression version 2.0 is here.
Description:
My Parallel Compress Library supports Parallel Gzip , Parallel Bzip
and Parallel LZMA algorithms, it works on TStreams, that means
it supports TMemoryStreams and TFileStreams etc.. and it uses
my Thread Pool Engine that implements work-stealing and that
uses a lock-free worker queue for each worker thread for more
efficiency.
Please look at test_pgzip.pas , test_pbzip.pas and test_plzma.pas
demos inside the zip file, compile and execute them... -
Language: FPC Pascal v2.2.0+ / Delphi 7+: http://www.freepascal.org/
Note: Parallel Gzip , Parallel Bzip work with both FreePascal and Delphi ,
but Parallel LZMA works only with Delphi 7 and up.
Operating Systems: Win , Linux and Mac (x86).
Note: to be able to port to Linux and Mac OSX you have to compile
the dynamic libraries...
You can download my Parallel Compression LIbrary version 2.0 from:

Hello,
What's next after Parallel Compression Library version 2.0 ?
As i have promised Parallel Compression Libray 2.0 is here..
Now, i have talked about another project that compiles an
Object Pascal Program toPetri Net Model and analyse it automaticly
for deadlock etc. but i think i will start anotherproject before this
one, this projectwill show how to use the Object Pascal language and
Object Pascal compilers to model andresolveOR(operational
research)problems in Linear programming and Integerprogramming
like:
Scheduling problem
Maximum Flow problem
Shortest-Path problem
Minimum cost flow
etc.
Andi will give you the source code in Object Pascal of all those kind of modeling problems...
I am right now working and preparing the article and the source code in Object Pascal..
Regards,
Amine Moulay Ramdane.

>Amine,
>and gzip implementation?
Hello Gennady Fedorov,
I havebenchmarked for examplemy PGzip against pigz.exe, and it gives
the same performanceas pigz.exe.
I think it's the same for PBzip2.exe and my parallel bzip...
You can benchmark IPP compression against pigz.exe and pbzip2.exe and
see what it's the result , it will give you an idea how my parallel compression
library perform..
http://www.zlib.net/pigz/
http://compression.ca/pbzip2/
Note also that pigz.exe and pbzip2.exe do notwork on TMemoryStreams ,
my parallel compression library do work with both TFileStream and TMemoryStreams...
Sincerely,
Amine Moulay Ramdane.
