Hi Guys,
First of all, thank you all for responding so quick, it is so
nice to see D having such an active community.
As I said in my first post, I used no other parameters to dmd
when compiling because I don't know too much about dmd
compilation flags. I can't wait to try the flags Daniel
suggested with dmd (-O -release -inline -noboundscheck) and
the other two compilers (ldc2 and gdc). Thank you guys for
your suggestions.
Meanwhile, I created a git repository on github and I put
there all my code. If you find any errors please let me know.
Because I am keeping the results in a big array the programs
take approximately 8Gb of RAM. If you don't have enough RAM
feel free to decrease the size of the array. For java code
you will also need to change 'compile-run.bsh' and use the
right memory parameters.
Thank you all for helping,
Iov

Sorry, forgot about it:

For posix-style threads, a per-thread workload of 200 calls to
log seems rather small. It would interesting to see a graph of
execution-time as a function of workgroup-size.
Traditionally one would use a workgroup size of (nElements /
nCores) or similar, in order to get all the cores working but
also minimise pressure on the scheduler, inter-thread
communication and so on.
