In the HPC context, these words are used by the big labs to refer to
of acquisitions. The largest systems (Roadrunner, any Petaflop system)
"capability" systems, the idea being that they can do something that
can't be done with a lesser machine.
"Capacity" machines tend to be run-of-the mill blocks of 10 TF or so,
cores or so, that bulk up the aggregate throughput capacity of the
collection of systems. They are intended for large numbers of medium
So Sandia's "Thunderbird" seems to be viewed as a capacity system,
terribly special about it, but it can get a bunch of work done.
