[Beowulf] cluster building for teaching (on the cheap)

I would suggest looking at the LittleFe project.

http://littlefe.net/
http://littlefe.net/index.php/Main_Page

For ~$2,500 you can purchase 8 small boards in a case that is less than 
50 lbs and can be checked as luggage at an airport.  Of course if you 
had $5,000 you could easily double the capacity of the LittleFe cluster 
by purchasing two.  The benefit of the LittleFe project is that it is 
designed with Computational Science in mind. (i.e. Computational 
Physics) I'm positive the coordinators of the project would be happy to 
work with you on curriculum modules for the cluster as well.  They might 
even have some curriculum modules for your physics class already in 
their collection.

If you would like more information or would like to discuss this further 
please let me know.

Thanks,
Eric Shook
