About my parallelsort library ...
«

Hello,
If you take a look at the graph of the benchmarks that i did on
my parallelsort library , you will notice that i am getting a superlinear
speed up , look at this:
http://pages.videotron.com/aminer/parallelsort/parallelsort.htm
So a question follows:
How am i getting this superlinear speed up on this example using
10 millions of strings?
My answer:
Cause when you are using mutliple threads and mutiple cores,
my parallelsort library is maximizing BETTER the locality , that means
the caches are used more efficiently when more threads and more cores
are used .
You can download my parallelsort library from:
http://pages.videotron.com/aminer/
Thank you.

Nice.
There are so many interesting things on your page (and I have not enough time to testing).

I mean exploit better the cache locality.
