Well, it's been awhile since I've written anything here... over 3 years! And, yeah, I'm still working on my Ph.D. at UK (U. of KY). I'm at my sister's in Atlanta for the holidays.
The FNN stuff we (myself and my advisor, Hank) started developing in 2000 has lead to all sorts of stuff. Too much to go into right now. As a side note, that little $10K cluster from Oct 2000 was called the KRAA Z-MP and actually turned out to be a real pain... Someday I might write up an article about what not to do when building a PC cluster... It's been decomisioned and several of the nodes are now workstations in one of our labs.
The cluster worth checking out is our new 128+4 node creation KASY0 which we built this summer.
