Hello, I have ported my Parallel Sort library to the delphi XE versions on the Win32 and Win64 platforms... Since i have only a computer with a Quadcore, i have tried to do a scalability prediction using the Amdahl equation of my Parallel Sort library and the numbers are good, and since i have completly parallelized the sorting part and the merging part, my Parallel Sort library is more scalable than my Parallel Quicksort library since on the parallel quicksort you can not completly parallelize the partition() procedure and you will still have a serial part in the partition() procedure that is big.. that makes my Parallel Sort library more scalable on multicores, but you have to know that on Quadcore the difference is not by much, but as soon as you use more cores than 4 cores my parallel sort library will be more scalable than my Parallel Quicksort. So all in all i have brought to you a good an interresting parallel library to add to your libraries. You can download my Parallel Sort library from: https://sites.google.com/site/aminer68/parallel-sort-library For the Delphi XE versions you have to download the zipfile called "parallelsort_xe.zip" and for the FreePascal and for Delphi 7 to Delphi2007 you have to download the zipfile called "parallelsort.zip" Thank you, Amine Moulay Ramdane.

Hello, The Quicksort implementation inside my Parallel Sort library uses the median-of-three, and i have also modified its partition() function so that it avoids worst case performance, so it's really fast. Thank you, Amine Moulay Ramdane.
