Hello, ParallelSort library has been updated to version 2.12.. In the previous version i have parallelized only the sort part, but in this version i have parallelized also the merge procedure part and it gives better performance. You can download parallelsort library version 2.0 from: http://pages.videotron.com/aminer/ Description: Parallel Sort Library that supports Parallel Quicksort, Parallel HeapSort and Parallel MergeSort on Multicores systems. Parallel Sort Library 2.0 uses my Thread Pool Engine and quicksort many array parts - of your array - in parallel using Quicksort or HeapSort or MergeSort a nd after that it finally merge them - with the merge() procedure - Parallelizing the Sorts One way to parallelize the sorts is: Divide the data among the processors Sort the data on the individual processors. Merge the various data Note that the merge operation is a reduction operation ! And please look at test.pas a parallel quicksort on many cores - compile and execute it... Language: FPC Pascal v2.2.0+ / Delphi 7+: http://www.freepascal.org/ Operating Systems: Win , Linux and Mac (x86). 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+ Thank you. Amine Moulay Ramdane.
