I was under the impression the O2k memory bandwidth was limited to
~800MB/s. If so, even if you can read 4GB/s what are you foing to do with
it? It would have to go over the CrayLink "network" and that doesn't do
4GB/s. The only way I can see 4GB/s disk throughput is multiple of the
node accessing "local" drives and adding all the bandwidth together.
