I'm not sure what the max capacity is.  You'll need to look at the Altix
web page[1] for the specifics.  I'd guess that the machine is configured
with 256G of RAM, but a portion of that is reserved for ccNUMA
directories.  

We have numerous changes to the standard kernel.  Most of them are to
support our platform and improve performance.  I don't think any changes
were needed to reach 64p or 256G of RAM, but I'm not an authoritative
source for that information.
