I've just completed initial installation and startup of a new BioBrew cluster with Marcelo Siero. We both were in Bruce Moxon's Parallel Computing class at UCSC Extension. I'm very pleased with the ease of installation. Almost all the difficulties we've run into so far were hardware problems; we built the cluster from 1U boxes purchased at auction from a defunct dot-com. Anyway looks like things are running well and it's time to start running some benchmarks and other jobs to get familiar with Grid Engine, and the many other packages there. I will agree with Kip's earlier post that it would be advantageous to install frontend nodes with ext3. I agree that compute nodes may as well run ext2.
