Dear Bin,
the xt3 files are to my knowledge for catamount, the old OS, very few
sites use this days. If the machine has been moved (most of them are)
to what is colloquial called "compute node linux" or "CNL" you should
start with the XT architecture files. If that is all cryptic to you,
ask you local guys, whether they are using catamount or CNL. By the
way, which XT3 are you using? Did the support team not put a Namd 2.7b1
out for you?
Hope this helps
Joachim
