Congratulations, well done and well deserved! Your work on the Mac Pro workstation with the WRF is very inspiring. I am now convinced to sell my MacBook Pro and buy a new Mac Pro tower because of your fine work. VMware Fusion is sweet but it would be cool if we could somehow get the WRF to compile and run on bare metal on the host (Mac OS X)! I'd be happy to help you figure this out if you're interested (logically the WRF should run faster than CentOS as a virtual machine). See also my private email correspondence on the WRF forum (I'm also very interested in using GPUs such as for some of the microphysics, per John Michalakes, et al articles).
