A 1024 node CM-5 could sustain 90% or more of its peak bandwidth, which
is 1024 * 4 * 16M * 8 = 512 GB/s. (It can run at over 99% of that, if
you are doing something especially trivial like adding up the entries in
a very large array.) Of course this is just between the vector units
and their local memories.
