The figures cited don't measure the kind of latency that I consider
important in any likely audio system running on Beowulf.
I would be excited about these figures if they were for the *first*
packet after, say, 10ms of no packets at all. If they are, then
whoo-hoo!

well, it depends on whether you're doing production/mixdown, or
real-time performance. most of my interest is in the latter, which is
why, for example, i consider quasimodo to be an instrument rather than
an equivalent to, say, ProTools or Logic.
but sure, if you're mixing down 128 stereo tracks of 32bit/192KHz
audio, a beowulf cluster or three would be mighty handy, and would
work just fine.
