Note that the only xt3 I have used has catamount, and that is what the
configure script options I gave are for. The xt4 was very different with
compute node linux - I hand-developed a script for franklin at nersc for
this which is probably the same thing that Ross has. The only info I have
been able to find on sapphire indicates it is a catamount xt3, but ERDC was
supposed to get an XT4 at some point in 2008. Should you actually have an
xt4, either Ross' script or my old script from franklin would be best
(please just request if you need it).
