Right. I wasn't implying it would do harm.

As for the x11 choice: I prefer to keep the change vectors
minimal. Otherwise you go nuts trying to debug things.

But it's good to see that you now understand that you have to start
'at the top' with Intel icc, and once you have a working R with you
can start working towards packages.  It's like a port to a different
platform as you completely switch the toolchain.

Good luck and keep us posted. I have looking at icc on the TODO list
too (for my C++ code, though, given R's interactive nature I think
there are lower hanging fruits elsewhere...)

Lastly, as to the benchmarking: It's difficult. Ripley once snarled
that it is probably the application you want to run the most so
there you go ...

Three out of two people have difficulties with fractions.
