While I agree that it's got a bit out of hand, I would assert that
parts of this discussion *have* been relevant to people building and
running Beowulf systems, because these systems are close to useless
unless programmed properly, no matter how smart we've been designing
and building the clusters we provide.
Many of us do have political issues to do with recruitment and skills
balances. It's actually quite useful to discuss these issues, as long
as we don't get too bogged down in flame wars. These issues are very
relevant to successful beowulf computing; as others have said getting
this wrong can cause performance problems of two or more orders of
magnitude, which is much worse than the difference between (say) using
infiniband and GigE for the interconnect. So one could argue that
getting the programming culture right is actually *more* important
than some of the technical details we like to get so bogged down in.
