The world's cheapest supercomputer, built by a Calvin College CS professor Joel Adams and student Tim Brom is very interesting. They built an 8 core Beowulf cluster using four motherboards and a gigabit network switch for less than $2500. The resulting machine has a price/performance ratio of $100/Gigaflop. That's just plain fun. I think there ought to be a yearly competition of this sort for students. Who can build the fastest supercomputer for $2500? Update: here's Joel Adams' website

Ara T Howard(click to enlarge) Ara T Howard, a research associate at The Cooperative Institute for Research in Environmental Sciences, is speaking about Ruby Queue, a tool for distributing the workload to nodes in a Linux cluster. He wanted something lean and fast and considered the existing packages like openMosix too heavyweight. The queue doesn't do scheduling--the type of work his group does processes long jobs that use lots of nodes. He determined to build something extremely simple, an NFS mounted priority queue that nodes could pull jobs from as needed. NFS has lots of cruftiness, but the truth
