To test the software, Microsoft provided a RocketCalc Saturn four-node personal cluster equipped with eight AMD Athlon64 2GHz CPUs and 8GB of RAM. The Saturn is a cool piece of hardware regardless of the OS, and it highlights the market Microsoft seems to be targeting: the minicluster. Instead of running one large cluster in the datacenter, it's feasible to deploy something like the Saturn to an individual engineer's cube. Could this style of clustering become the eventual core market for CCS? Time will tell.
