Re: 64 bit G5 plans for NAMD

Apple doesn't have a 64-bit operating system for the G5 yet, so I'm not
sure it's even possible to build a 64-bit binary yet. I would expect the
IBM xlC compiler to provide a substantial performance boost, but we don't
have access to a G5 so I can't confirm this. NAMD builds with xlC on AIX,
so it should be possible for someone (e.g., you) to build a Mac G5 binary
from source and see what the actual performance is.

I've added some more material on the NAMD Wiki at
Feel free to add any relevant comments or results there (click EDIT).
