User's Perspective: General Case of Running Linux
We have installed a small foot-print Linux version on a WMWare VM and equipped it with the WRF software and all other tools (e.g. Compilers, Graphical tools, Libraries, etc.) needed to compile and run the system. We have also created some scripts to make the tasks of running a (basic) WRF simulation easy for the beginner. Even this system is able to take advantage of Dual Processor systems.
Finally we have packed everything to a DVD with a reasonable installation program so that the end-user can install it just as any other piece of windows software.
Copyright Issues
At the moment we use this DVD for trainings in various countries. However, it is not possible to release it for the public to download, simply because of the potential license issues. Some of the tools used within the DVD (e.g. VMware player, Intel's compilers for Linux, WRF model itself, etc.) are not freely distributable.
