I, for one, am interested mainly in NUMA and/or message-passing systems
with full ethernet connectivity for adminstration and a HPN for application
data (i.e. Myrinet, cLAN, SCI, etc).

The cluster I operate is described here:

http://www.hcs.ufl.edu/carrier/index.html

Note some of our "interesting" problems:

1) support for just about every HPN type out there (though not simultaneous)
2) heterogeniety (some SMP nodes, some uniprocessor; different clock speeds)
3) mixture of OS (ugh!)

Problem 1) puts me in a position to be able to test all kinds of fun stuff,
but often means I'm maintaining three or four different kernel versions
across the clusted since SCI only works with such-and-such a kernel, Myrinet
with a different version, etc.  

Problem 2) is probably the most interesting one from a load-balancing
standpoint.  Most clusters (esp. shoestring-budget clusters) probably will
"grow" over time, meaning not all processors will be of the same capability.
