Is a gigabit backbone really necessary?
It is. With a cluster of machines, network itself can become biggest bottle neck. Clusters normally use Infiniband ethernet, not even gigabit.
Network IS the bottleneck. Particularly in graphics applications. So let's say u have no cpu-mem bottleneck, a node will pump out 200Mbps of data. Next bottleneck is PCI then cpu-mem and finally cpu mips. So with a P4 mobo and 1Gbps network u can have 10 nodes max.
