Douglas Eadline writes "Read this article and become a cluster design expert! Use a new tool from the aggregate.org to determine price and performance before you buy! Get a handle on everything from Ethernet cables, to GFLOPS, to power and cooling.
Whenever someone asks what hardware to buy for their new cluster, the answer is always, "It depends." It depends on what application the cluster will be used for, it depends on how much space, power, and cooling are available, it depends on the costs of operating the cluster, and it depends on how much the parts that might be used cost. The standard process is to analyze the application and use rules of thumb and experience to guess what hardware will work best. This new tool answers these questions in an analytical way and keeps guessing to a minimum."
