I come from an HPC background and used beowulf/warewulf and perceus cluster
software for scientific computing. This is linux software and we prefer
FreeBSD for our bro clusters, but I've been laying the ground work for a
memory file system bro cluster (with local scratch). Our next cluster will
likely be built this way. But if you go down this path and want to compare
notes, let me know.
