These types of questions are the same as "how tall is a building?"
It all depends on what you want to do.
Rather than have Robert rehash his lesson, you can find
a write-up here:
> Hi All,
> Which one of the following two choices are better (assuming both
> clusters have nearly same cost):
> 1) A 4-node cluster having 8 AMD Opteron of 2.6GHz each and 2GB RAM/node
> 1) A 5-node cluster having 10 AMD Opteron of 2.2GHz each and 2GB RAM/node
> Consider GiGE (max 1000mbps) as the interconnect.
> Is there any significant performance difference between the two?
> Does the compasison depends on the MPI communication among nodes, for
> a given application?
> Thanking all in anticipation.
