does OpenFoam take advantage of 64bit OS?

I installed the 64bit AMD Ubuntu 11.10.
Will OpenFoam, out of the box, take advantage of the extra power, or is there another version I need to install?

Well, it depends. Technically it is indeed installed the OpenFOAM version for 64bit, because you are using the 64bit version of Ubuntu.
Nonetheless, the compiled version is usually not fully optimized for all processors. Which means that to take full advantage of your machine's CPU features, you should do your own build of OpenFOAM: http://www.openfoam.org/download/source.php
Last but not least: if you have Ubuntu 64bit installed inside a virtual machine, I don't think it will do much difference if you build your own version, because you'll always be missing out on your machine's true power
