From my personal play with icpc, you need to compile a dedicated version
of boost libraries for it (you cannot reuse the one installed for gcc in
/usr/lib : the headers are fine, but the libraries are not)

Then it's only a matter of setting the environment with the icc script
to compile. And it run benchmark in very good time (~130 s vs ~155 s)

More technical details if still needed tonight (about 6 hours away),
once I'm back on the actual system with icc. (but I'm not sure it was in
the 12 serie or not)
