When working on high performance supercomputers, network latency and bandwidth are of utmost importance. If messages cannot be sent quickly enough between compute nodes, a supercomputer may actually perform more poorly than a standard server or workstation. So much time is spent waiting for input from other locations that nothing is actually accomplished. These days, more time is spent optimizing latency than bandwidth since most clusters have all the bandwidth they need (2-4GB/sec).

I've discovered that an analogy can be made with traffic on the highway. Computers keep getting faster, and now maybe traffic can too. I promise you'll notice this the next time you head out on the road.   read more >>
