Only point above was commercial machines like Sun10000 or SGIOrigin, mostly
runs single operating system for n-proc machine at least end user point of 
view. In Beowulf-type solutions we have to care about n-OS, for instance
if you have heterogeneous environment (iff you have!), at least you have to
compile running program twice. Upgrading and writing automation scripts,
counts as maintenance cost. Isn't it?  Anyway, compare to
gain,boost by linux stability is worth to invest on Beowulf.
