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.
