Gcc and even icc are not really good at code vectorisation. IMHA it is a 
better idea to parallel the code manually using the SSE instructions, you 
will get better performances.
I can try to look at the code, and see if there is room for optimisations.
But I'm very new to this project, and I think there is more experimented 
programmers than me on this list.
